Derivatives Level 4 (Investment Advice Diploma) Quiz Exam Quiz 30

The question assesses the understanding of exotic derivatives, specifically barrier options, and their sensitivity to market movements near the barrier. A knock-out call option ceases to exist if the underlying asset’s price reaches the barrier level before the option’s expiration. The value of such an option is highly sensitive to the proximity of the underlying asset’s price to the barrier, especially as the expiration date approaches. The scenario involves a fund manager, Sarah, who uses a knock-out call option to hedge a portion of her portfolio. The underlying asset is trading close to the barrier level, and the option is nearing expiration. The question explores how different market events will affect the option’s value and, consequently, Sarah’s hedging strategy. The correct answer focuses on the gamma and theta effects. Gamma represents the rate of change of delta with respect to the underlying asset’s price, and theta represents the rate of change of the option’s value with respect to time. As the option nears expiration and the underlying asset’s price is close to the barrier, the gamma and theta become very large. A small price movement can significantly impact the option’s delta, and the time decay accelerates. For instance, imagine the knock-out barrier is set at £110. Currently, the underlying asset trades at £109.90. If the price jumps to £110.01, the option is immediately knocked out and becomes worthless. Conversely, if the price drops to £109.80, the option still exists, but its value might not increase linearly because the likelihood of it being knocked out soon is still high. This non-linear behaviour around the barrier is due to high gamma. The closer the expiration, the faster the option loses value if the barrier isn’t breached, illustrating the theta effect. The incorrect options present plausible but flawed reasoning. One option focuses on vega, which measures sensitivity to volatility, but it is less critical than gamma and theta in this scenario. Another option highlights rho, which measures sensitivity to interest rates, but it has a minimal impact in this short-term, barrier-sensitive situation. The last incorrect option discusses delta, which measures sensitivity to price changes, but it doesn’t capture the accelerated impact of gamma and theta near the barrier as expiration nears.

Let’s consider a scenario where a UK-based agricultural cooperative, “Green Fields Collective,” aims to hedge against potential price drops in their upcoming wheat harvest using futures contracts listed on the ICE Futures Europe exchange. They anticipate harvesting 5,000 tonnes of wheat in three months. The current futures price for wheat with delivery in three months is £200 per tonne. The cooperative decides to sell 50 wheat futures contracts, each representing 100 tonnes of wheat (50 contracts * 100 tonnes/contract = 5,000 tonnes). Three months later, at harvest time, the spot price of wheat has fallen to £180 per tonne. Green Fields Collective sells their wheat in the spot market for £180 per tonne, receiving £900,000 (5,000 tonnes * £180/tonne). Simultaneously, they close out their futures position by buying back 50 wheat futures contracts. The futures price at this time is also £180 per tonne. The profit from the futures contracts is calculated as follows: Initial selling price – Final buying price = £200 – £180 = £20 per tonne. Total profit from futures contracts = £20/tonne * 5,000 tonnes = £100,000. The effective price received by Green Fields Collective is the spot market price plus the profit from the futures contracts: £900,000 (spot market revenue) + £100,000 (futures profit) = £1,000,000. The effective price per tonne is £1,000,000 / 5,000 tonnes = £200 per tonne. However, basis risk exists because the futures price and the spot price may not converge perfectly at the delivery date. If, for example, the futures price had been £185 instead of £180 at the delivery date, the profit from the futures contracts would have been £15 per tonne (£200 – £185), totaling £75,000. The effective price received would then be £900,000 + £75,000 = £975,000, or £195 per tonne. This difference illustrates basis risk. A key aspect of hedging effectiveness is the correlation between the asset being hedged (wheat) and the hedging instrument (wheat futures). If Green Fields Collective had used a less correlated futures contract (e.g., corn futures), the hedging effectiveness would be significantly reduced, increasing the basis risk. Regulatory frameworks, such as those outlined by the FCA, require firms advising on derivatives to ensure clients understand these risks and the suitability of the hedging strategy. The Markets in Financial Instruments Directive (MiFID II) also emphasizes the need for firms to assess the appropriateness of complex financial instruments like derivatives for their clients.

Let’s break down the valuation of a cliquet option, particularly focusing on the ratchet and participation rate. A cliquet option, also known as a ratchet option, consists of a series of consecutive options with strike prices that are reset at the beginning of each period. The overall payoff is the sum of the payoffs of each individual option. A key feature is the ratchet, which sets a floor for the overall return, and a cap, limiting the maximum return. The participation rate dictates the percentage of the underlying asset’s gains that the option holder receives. Consider an initial investment of £1,000,000 in a cliquet option with annual resets, a participation rate of 80%, a floor of 2% per annum, and a cap of 10% per annum. We will analyze the first three years. Year 1: The underlying asset increases by 15%. However, due to the 10% cap, the cliquet option only gains 10%. With an 80% participation rate, the gain is 80% of 10%, which is 8%. Thus, the gain is £1,000,000 * 8% = £80,000. The new value is £1,080,000. Year 2: The underlying asset decreases by 5%. The floor is 2%, so the cliquet option guarantees a 2% gain. Thus, the gain is £1,080,000 * 2% = £21,600. The new value is £1,101,600. Year 3: The underlying asset increases by 3%. With an 80% participation rate, the gain is 80% of 3%, which is 2.4%. Thus, the gain is £1,101,600 * 2.4% = £26,438.40. The new value is £1,128,038.40. The total gain over the three years is £80,000 + £21,600 + £26,438.40 = £128,038.40. The percentage return on the initial investment is (£128,038.40 / £1,000,000) * 100% = 12.80384%. This example demonstrates how the participation rate, floor, and cap interact to determine the overall return of a cliquet option. The ratchet feature (floor) protects against losses, while the cap limits gains, and the participation rate adjusts the extent to which the investor benefits from the underlying asset’s performance. The reset mechanism ensures that each period’s gains are calculated based on the new value of the investment.

Let’s break down how to approach this exotic option pricing problem, which involves a barrier option with a twist. We’ll use a simplified binomial model for illustration, although in practice, more sophisticated models are needed for accurate pricing. This specific barrier option is a “knock-out” option, meaning it ceases to exist if the underlying asset’s price hits a predetermined barrier level. Furthermore, the barrier level changes over time, adding another layer of complexity. First, we need to model the potential price movements of the underlying asset (in this case, shares of “TechFuture”). We’ll assume a simplified two-period binomial model. Let’s say the current price of TechFuture is £100. In each period, the price can either go up by 10% or down by 10%. The barrier starts at £85 and increases by £2 each period. Period 1: * Up move: £100 * 1.10 = £110 * Down move: £100 * 0.90 = £90 Period 2: * Up-Up move: £110 * 1.10 = £121 * Up-Down move: £110 * 0.90 = £99 * Down-Up move: £90 * 1.10 = £99 * Down-Down move: £90 * 0.90 = £81 Now, let’s consider the barrier. It starts at £85 and increases by £2 each period. So, in period 1, the barrier is £85, and in period 2, it’s £87. * If the price goes down to £90 in period 1, the option is still alive because £90 > £85. * If the price goes down-down to £81 in period 2, the option is knocked out because £81 < £87. Next, we determine the payoff of the option at expiration (period 2). This is a European call option with a strike price of £105. * Up-Up: £121 – £105 = £16 * Up-Down: £99 – £105 = -£6 (Since the payoff cannot be negative, it's £0) * Down-Up: £99 – £105 = -£6 (Since the payoff cannot be negative, it's £0) * Down-Down: Knocked out, payoff = £0 Now, we need to discount these payoffs back to the present value. We'll assume a risk-neutral probability of 0.5 for both up and down moves and a risk-free rate of 5% per period. Period 1: * Value after Up move: \( \frac{0.5 \cdot 16 + 0.5 \cdot 0}{1.05} = 7.62 \) * Value after Down move: \( \frac{0.5 \cdot 0 + 0.5 \cdot 0}{1.05} = 0 \) Period 0: * Value of the option: \( \frac{0.5 \cdot 7.62 + 0.5 \cdot 0}{1.05} = 3.63 \) Therefore, the approximate price of the exotic barrier option is £3.63. The key here is understanding how the barrier impacts the option's value at each step and how the knockout feature affects the final payoff calculation.

The question assesses the understanding of exotic derivatives, specifically a cliquet option, and how its payoff structure affects its valuation and suitability for different investment objectives. A cliquet option is a series of options, where each option’s strike price is determined by the performance of the underlying asset in the previous period. This creates a path-dependent payoff, making it more complex than standard options. The investor’s risk aversion and investment horizon are crucial factors in determining the suitability of such a derivative. The payoff of a cliquet option is calculated by summing the returns of the underlying asset over discrete periods, subject to a cap and a floor. For example, if an investor holds a one-year cliquet option with quarterly resets, a 5% cap, and a 0% floor, the payoff is the sum of the quarterly returns, each capped at 5% and floored at 0%. Consider an asset with the following quarterly returns: Q1: 8%, Q2: -3%, Q3: 6%, Q4: 2%. The cliquet option payoff would be 5% (capped) + 0% (floored) + 5% (capped) + 2% = 12%. The suitability of a cliquet option depends on the investor’s risk profile and investment goals. A risk-averse investor might prefer the capped gains and floored losses, while a risk-seeking investor might find the capped gains limiting. The investment horizon also plays a role. A short-term investor might be more sensitive to the volatility of the underlying asset, while a long-term investor might be more interested in the potential for compounded returns. Furthermore, regulations like MiFID II require firms to assess the suitability of complex instruments like cliquet options for their clients. This assessment must consider the client’s knowledge and experience, financial situation, and investment objectives. Failure to conduct a proper suitability assessment can result in regulatory penalties.

The core of this question lies in understanding how regulatory frameworks like MiFID II impact the suitability assessment process for complex financial instruments like exotic derivatives. The scenario presented requires the advisor to not only understand the client’s risk profile but also to navigate the specific regulatory requirements surrounding the sale of such products. First, we need to ascertain the core principle: MiFID II mandates a higher level of scrutiny for complex instruments. This scrutiny is reflected in the detailed information gathering required to determine suitability. Second, we need to analyze the provided options. Option (a) correctly identifies the need to obtain explicit confirmation that the client understands the potential for significant losses *beyond* the initial investment. This is a critical aspect of suitability for leveraged instruments and exotic derivatives. MiFID II emphasizes the need for clients to fully comprehend the risks they are undertaking, especially when those risks are not immediately apparent. Option (b) is incorrect because, while assessing the client’s overall portfolio diversification is important, it is not the *most* critical aspect in this specific scenario. The focus is on the client’s understanding of the derivative itself. Option (c) is incorrect because, while past performance can be an indicator, it’s not a guarantee of future results and shouldn’t be the primary factor in determining suitability, especially for derivatives. Derivatives are inherently volatile, and relying solely on past performance is a flawed approach. Option (d) is incorrect because, while the client’s net worth is a factor, it’s not the *most* crucial element. A wealthy client can still be unsuitable for a complex derivative if they lack the necessary understanding of the risks involved. MiFID II prioritizes client comprehension over simply having the financial means to absorb potential losses. Therefore, the advisor’s primary responsibility is to ensure the client fully understands the potential for losses exceeding the initial investment. This understanding must be explicitly confirmed and documented. This aligns with the core principles of MiFID II, which aims to protect investors by ensuring they are fully informed about the risks associated with complex financial products. A suitable analogy is a surgeon explaining the risks of a complex operation: even if the patient can afford the procedure, the surgeon must ensure they understand the potential complications before proceeding. Similarly, the advisor must ensure the client understands the potential downsides of the exotic derivative. This ensures the client is making an informed decision and not simply speculating based on incomplete information. The advisor should explain how the derivative works, how its value is derived from the underlying asset, and how various market conditions could impact its value.

The question assesses the understanding of how early termination clauses in swap agreements are valued, specifically considering the impact of market volatility and correlation between underlying assets. The calculation involves estimating the potential future exposure (PFE) and netting it against the market value of the swap. The PFE is derived from the volatility and correlation of the underlying assets. Here’s the step-by-step calculation: 1. **Calculate the Potential Future Exposure (PFE):** The PFE is estimated based on the volatility of the underlying assets and their correlation. The formula to approximate PFE is: \[PFE = Notional \times \sqrt{\sigma_1^2 + \sigma_2^2 – 2 \rho \sigma_1 \sigma_2} \times Multiplier\] Where: * \(Notional = £50,000,000\) * \(\sigma_1 = 0.15\) (Volatility of Asset A) * \(\sigma_2 = 0.12\) (Volatility of Asset B) * \(\rho = 0.6\) (Correlation between Asset A and Asset B) * \(Multiplier = 2.5\) (Given Multiplier) Plugging in the values: \[PFE = 50,000,000 \times \sqrt{0.15^2 + 0.12^2 – 2 \times 0.6 \times 0.15 \times 0.12} \times 2.5\] \[PFE = 50,000,000 \times \sqrt{0.0225 + 0.0144 – 0.0216} \times 2.5\] \[PFE = 50,000,000 \times \sqrt{0.0153} \times 2.5\] \[PFE = 50,000,000 \times 0.12369 \times 2.5\] \[PFE = £15,461,250\] 2. **Calculate the Net Exposure:** The net exposure is the difference between the PFE and the current market value of the swap. \[Net \ Exposure = PFE – Market \ Value\] \[Net \ Exposure = 15,461,250 – 2,500,000\] \[Net \ Exposure = £12,961,250\] Therefore, the estimated exposure under the early termination clause is £12,961,250. Analogy: Imagine two ships (Assets A and B) sailing in the ocean. Their paths are somewhat correlated (0.6). The volatility of each ship’s course represents how much they deviate from their intended path. The higher the volatility and the lower the correlation, the wider the potential spread between the ships. The notional amount is like the size of the ships, and the multiplier amplifies the potential exposure. The market value is like an existing insurance policy that offsets some of the potential losses. The net exposure is the remaining risk after considering the insurance. A portfolio manager must understand these calculations to assess the true risk exposure of their derivative positions. It is not just about the current market value but also the potential future changes, especially when early termination clauses are involved. The manager must also consider the legal and regulatory implications under UK law, such as the Financial Collateral Arrangements (No. 2) Regulations 2003, which governs the enforceability of such clauses. Understanding these regulations is vital for ensuring the enforceability of the early termination and close-out netting provisions in the event of counterparty default.

The question assesses the understanding of exotic derivatives, specifically barrier options, and their valuation implications under different market conditions. A down-and-out call option becomes worthless if the underlying asset’s price touches or falls below the barrier level. The initial premium reflects the probability of the barrier being hit before expiration. A significant drop in implied volatility reduces the likelihood of the barrier being breached, thus increasing the option’s value. A decrease in the risk-free rate generally increases the value of call options, as the present value of future payoffs rises. However, this effect is usually smaller than the impact of volatility changes, especially for barrier options close to the barrier. An increase in the underlying asset’s price moves it further away from the barrier, decreasing the probability of the option being knocked out and thus increasing its value. The initial value is £5. A 20% decrease in implied volatility significantly reduces the probability of hitting the barrier. Let’s assume this increases the value by £3. A 0.5% decrease in the risk-free rate provides a smaller boost, say £0.50. A £2 increase in the underlying asset’s price moves it further from the barrier, adding another £1 to the value. New Value = Initial Value + Volatility Effect + Risk-Free Rate Effect + Price Effect New Value = £5 + £3 + £0.50 + £1 = £9.50 Therefore, the estimated new value of the down-and-out call option is £9.50. This illustrates how changes in market conditions impact the valuation of exotic derivatives, requiring a nuanced understanding beyond simple delta calculations. The scenario emphasizes the combined effect of volatility, interest rates, and underlying asset price on barrier option pricing.

Let’s break down this complex swap scenario. The core concept here is the calculation of the fixed rate in an interest rate swap. We need to determine the rate at which both legs of the swap have the same present value. The floating leg payments are based on the LIBOR forward curve, and we discount these expected future cash flows using the spot rates to arrive at their present value. The fixed leg is a series of payments discounted at the same spot rates. The present value of the floating leg is calculated by discounting each of the expected future LIBOR payments. The 6-month LIBOR rate applicable at each reset date is given. We use these rates to determine the expected interest payment for each period. We then discount these payments back to time zero using the corresponding spot rates. For example, the first payment is calculated as follows: The 6-month LIBOR rate is 5.00%, so the interest payment on a notional principal of £1,000,000 is £1,000,000 * 0.0500 * (180/360) = £25,000. This payment is discounted back to time zero using the 6-month spot rate of 4.75%, so the present value is £25,000 / (1 + 0.0475 * (180/360)) = £24,414.63. This process is repeated for each of the subsequent periods. The present value of the fixed leg is calculated similarly, but we are solving for the fixed rate. Let the fixed rate be denoted by ‘r’. The fixed payment for each period is £1,000,000 * r * (180/360). We discount these payments back to time zero using the corresponding spot rates. The goal is to find the fixed rate ‘r’ such that the present value of the fixed leg is equal to the present value of the floating leg. This can be done iteratively or using a numerical solver. In this case, the fixed rate that equates the present values of the two legs is approximately 5.35%. Therefore, the fixed rate the bank should quote is 5.35%. This rate ensures that the present value of the fixed payments matches the present value of the expected floating payments, making the swap fair at inception. A higher rate would favor the bank, while a lower rate would favor the counterparty.

The question revolves around the concept of a variance swap and its valuation, particularly focusing on the impact of realized variance exceeding the variance strike. A variance swap pays the difference between the realized variance of an asset and a pre-agreed variance strike. The payoff is typically calculated at the maturity of the swap. Realized variance is the actual volatility observed over the life of the swap, while the variance strike is the level agreed upon at the start. The notional amount scales the payoff. The formula for the payoff is: Notional Amount * (Realized Variance – Variance Strike). In this scenario, realized variance is 280 basis points squared, and the variance strike is 250 basis points squared. The difference is 30 basis points squared (0.0030). The notional amount is £50,000 per variance point. Since the variance is expressed in basis points squared, each basis point is 0.0001. Therefore, one variance point is (0.0001)^2 = 1e-8. So the notional amount is £50,000 / (1e-8) = £5e12 per variance unit. The payoff is then £5e12 * 0.0030 = £15,000,000. Now, let’s consider the impact of the counterparty’s default after only 6 months. Since the swap has a one-year term, there are still 6 months remaining. The party that is “in the money” (i.e., the party to whom money is owed) becomes a creditor in the defaulting counterparty’s bankruptcy. In this case, the party that benefits from the variance swap (due to realized variance exceeding the strike) is owed money. The amount owed is the present value of the expected payoff at maturity. The present value is calculated by discounting the payoff back to the valuation date using the appropriate discount rate. Assuming a discount rate of 5% per annum, the discount factor for 6 months (0.5 years) is \(e^{-0.05 \times 0.5}\) = \(e^{-0.025}\) ≈ 0.9753. The present value of the payoff is £15,000,000 * 0.9753 = £14,629,500. This represents the estimated loss due to the counterparty default.

The correct answer is (a). The question assesses the understanding of how margin requirements work in futures contracts, specifically the impact of price fluctuations on the margin account and the resulting actions (margin calls or withdrawals). The initial margin is the amount required to open the position, and the maintenance margin is the level below which the account cannot fall. Here’s how to solve the problem: 1. **Initial Margin:** £8,000 2. **Maintenance Margin:** £6,000 3. **Price Drop:** 10 points, each point worth £200, so a total loss of 10 * £200 = £2,000. 4. **Margin Account Balance After Drop:** £8,000 (initial) – £2,000 (loss) = £6,000. 5. **Margin Call?** The balance is now at the maintenance margin level (£6,000). No margin call is triggered *yet*, because the balance is *equal* to the maintenance margin. 6. **Price Increase:** 5 points, each point worth £200, so a total gain of 5 * £200 = £1,000. 7. **Margin Account Balance After Increase:** £6,000 (previous) + £1,000 (gain) = £7,000. Therefore, the margin account balance is £7,000, and no margin call is issued because the balance is above the maintenance margin. The incorrect options present plausible scenarios that might arise from misunderstanding the timing of margin calls or the impact of price changes. Option (b) incorrectly assumes a margin call is triggered when the balance hits the maintenance margin, and then a withdrawal occurs after the price increase. Option (c) incorrectly calculates the total change in the margin account. Option (d) incorrectly assumes a margin call is triggered immediately when the balance hits the maintenance margin and then a withdrawal occurs after the price increase. This question requires understanding not just the definitions of initial and maintenance margin but also the dynamic process of how margin accounts are adjusted in response to price movements and when margin calls are triggered. The example uses specific numerical values and a scenario to test this deeper understanding.

Let’s analyze the scenario. A gold mining company wants to protect itself from a potential decrease in gold prices. They enter into a forward contract to sell gold at a predetermined price. However, their gold mine unexpectedly yields significantly less gold than anticipated. This shortfall creates a situation where they cannot fulfill the entire forward contract obligation with their own production. They must source the remaining gold from the spot market to meet their contractual commitments. The key is to calculate the financial impact of this shortfall, considering the forward contract price, the spot market price at the time of settlement, and the quantity of gold they need to purchase on the spot market. First, determine the amount of gold the company needs to source from the spot market: 100 kg (contracted) – 60 kg (produced) = 40 kg. Next, calculate the cost of purchasing this 40 kg on the spot market: 40 kg * £1,850/kg = £74,000. Then, calculate the revenue the company receives from the forward contract: 100 kg * £1,700/kg = £170,000. Finally, calculate the net financial outcome: Revenue from forward contract – Cost of spot market purchase = £170,000 – £74,000 = £96,000. The company still makes a profit, but it is significantly less than if they had produced the full 100 kg. This example illustrates the risks associated with forward contracts when actual production deviates from expected levels. It also highlights the importance of carefully estimating production capacity and considering potential supply chain disruptions. Unlike a futures contract, which is standardized and traded on an exchange, a forward contract is customized and privately negotiated, making it less flexible in situations like this. This scenario underscores the critical difference between hedging strategies and speculative trading, and how unexpected events can impact the effectiveness of a hedge. A swap, in contrast, would involve exchanging cash flows based on gold prices over a period, and an option would give the company the right, but not the obligation, to sell gold at a specific price. This forward contract commits them to a sale, regardless of their production shortfall.

The optimal hedge ratio in this scenario aims to minimize the variance of the hedged portfolio. This involves understanding the correlation between the asset being hedged (the shares of BioTech Innovators Inc.) and the hedging instrument (the FTSE 100 futures contract). The hedge ratio is calculated as: Hedge Ratio = (Correlation * (Volatility of Asset / Volatility of Futures)) First, we need to calculate the volatility of both the BioTech Innovators Inc. shares and the FTSE 100 futures contract. Volatility is represented by the standard deviation. Volatility of BioTech Innovators Inc. = 25% = 0.25 Volatility of FTSE 100 futures = 15% = 0.15 Correlation between BioTech Innovators Inc. and FTSE 100 futures = 0.7 Hedge Ratio = 0.7 * (0.25 / 0.15) = 0.7 * 1.6667 = 1.1667 This means that for every £1 of BioTech Innovators Inc. shares, approximately £1.17 of the FTSE 100 futures contract should be used to hedge the portfolio. The number of futures contracts needed is then calculated by dividing the total value of the shares to be hedged by the value of one futures contract and multiplying by the hedge ratio. Total value of BioTech Innovators Inc. shares = 50,000 shares * £10/share = £500,000 Value of one FTSE 100 futures contract = £10 * Index Level = £10 * 7500 = £75,000 Number of contracts = (Total Value of Shares / Value of One Futures Contract) * Hedge Ratio Number of contracts = (£500,000 / £75,000) * 1.1667 = 6.6667 * 1.1667 = 7.7778 Since futures contracts can only be traded in whole numbers, we round this to the nearest whole number. In this case, rounding 7.7778 gives us 8 contracts. Therefore, the portfolio manager should short 8 FTSE 100 futures contracts to hedge the portfolio effectively. This approach minimizes the portfolio’s exposure to market fluctuations by offsetting potential losses in the BioTech Innovators Inc. shares with gains in the shorted FTSE 100 futures contracts, and vice versa. The hedge ratio is a crucial element in achieving this balance. The use of correlation and volatility ensures that the hedge is tailored to the specific relationship between the asset and the hedging instrument.

The core of this question revolves around understanding how different derivative types react to volatility and time decay (theta), and how these factors influence hedging strategies. A straddle involves buying both a call and a put option with the same strike price and expiration date. This strategy profits from significant price movements in either direction. However, it is negatively impacted by time decay and, depending on the initial cost, may require a substantial price move to become profitable. The question further incorporates the concept of delta-hedging, which aims to create a portfolio that is neutral to small price movements in the underlying asset. A delta-neutral portfolio has a delta of zero, meaning that the portfolio’s value is not expected to change if the price of the underlying asset changes slightly. To maintain delta neutrality, the investor must continuously adjust the hedge ratio as the delta of the options changes with price movements and time. In this scenario, increased volatility benefits the straddle because it increases the likelihood of a large price movement that will make one of the options profitable. However, the higher volatility also increases the rate at which the options’ deltas change, requiring more frequent adjustments to the delta hedge. Time decay (theta) hurts the straddle, as both the call and put options lose value as they approach expiration. To offset this, the investor must profit from the delta hedge. If the underlying asset price remains relatively stable, the delta hedge will generate small profits as the investor buys low and sells high (or vice versa) to maintain delta neutrality. However, if the price moves sharply and frequently, the costs of adjusting the delta hedge may outweigh the profits. The key to answering this question is recognizing the interplay between volatility, time decay, and delta-hedging in the context of a straddle. High volatility requires more frequent delta adjustments, while time decay erodes the value of the options. The investor’s ability to profit depends on the balance between these factors.

The question assesses the understanding of exotic derivatives, specifically a cliquet option, and its sensitivity to correlation between underlying assets. A cliquet option is a series of options whose strike prices are determined by the performance of the underlying asset during the previous period. The overall return is capped, limiting potential gains, but also protects against significant losses. In this scenario, the correlation between the two assets is a crucial factor. Higher correlation generally reduces the volatility of a portfolio of assets, while lower or negative correlation increases it. In the context of a cliquet option on a portfolio, a higher correlation means the assets tend to move together, leading to less variability in the ratchet (periodic reset) strike prices. This decreased variability reduces the potential for large gains from the cliquet, as the strike prices are less likely to reset at significantly higher levels. Conversely, lower correlation increases the potential for larger gains, as the individual assets may experience more divergent movements, leading to higher ratchet strike prices in some periods. However, it also increases the risk of losses. The cap on the overall return is a key feature of cliquet options, mitigating the risk of extreme gains due to high volatility. Therefore, in a low correlation environment, the cap becomes more likely to be reached, limiting the upside potential. The value of the cliquet option is influenced by these dynamics, with higher correlation typically decreasing the option’s value and lower correlation potentially increasing it, up to the point where the cap is reached. The question also touches on the suitability of such products for different risk profiles. While cliquet options offer some protection against downside risk, the capped upside and the complexity of the product make it unsuitable for all investors. The investor’s understanding of correlation and its impact on portfolio volatility is essential before investing in such derivatives.

The optimal hedge ratio in futures contracts seeks to minimize the variance of the hedged portfolio. This is achieved by determining the number of futures contracts required to offset the price risk of the underlying asset. The formula for the optimal hedge ratio is: \[Hedge\ Ratio = \rho \cdot \frac{\sigma_s}{\sigma_f}\] Where: * \( \rho \) is the correlation between the spot price changes and the futures price changes. * \( \sigma_s \) is the standard deviation of the spot price changes. * \( \sigma_f \) is the standard deviation of the futures price changes. In this scenario, we are given \( \rho = 0.75 \), \( \sigma_s = 0.02 \) (2%), and \( \sigma_f = 0.03 \) (3%). The size of the gold holding is 100 kg, and each gold futures contract is for 1 kg. First, we calculate the optimal hedge ratio: \[Hedge\ Ratio = 0.75 \cdot \frac{0.02}{0.03} = 0.5\] This means that for every unit of the spot asset, we need 0.5 units of the futures contract to minimize risk. Since the investor holds 100 kg of gold, they need: \[Number\ of\ Contracts = Hedge\ Ratio \cdot Quantity\ of\ Gold = 0.5 \cdot 100 = 50\] Therefore, the investor should short 50 gold futures contracts to minimize the variance of their hedged position. The concept behind this calculation lies in minimizing the overall portfolio volatility. A perfect hedge (which is rarely achievable in practice) would completely eliminate price risk. The correlation factor adjusts the hedge ratio to account for the degree to which the spot and futures prices move together. If the correlation is low, the hedge ratio is reduced, indicating that futures contracts are less effective at offsetting spot price movements. Conversely, a high correlation results in a higher hedge ratio, implying a more effective hedge. The ratio of standard deviations adjusts for the relative volatility of the spot and futures prices. If the futures price is more volatile than the spot price, the hedge ratio is reduced to avoid over-hedging. Conversely, if the spot price is more volatile, the hedge ratio is increased to provide adequate protection against price fluctuations. In the real world, transaction costs, margin requirements, and basis risk (the risk that the spot and futures prices do not move perfectly in tandem) can impact the effectiveness of the hedge. Understanding these factors is crucial for implementing a successful hedging strategy.

Let’s break down how to determine the payoff of a knock-out barrier option and its implications for a portfolio. First, understand the core mechanics. A knock-out barrier option ceases to exist if the underlying asset’s price touches the barrier level before the option’s expiration. This feature makes them cheaper than standard options, but also riskier. In this scenario, we have a knock-out call option. The payoff is calculated as the maximum of zero and the difference between the asset’s price at expiration and the strike price, *only if* the barrier has not been breached. If the barrier has been breached, the option expires worthless, regardless of the asset’s price at expiration. Here’s the step-by-step calculation: 1. **Check for Barrier Breach:** The FTSE 100 started at 7500 and the knock-out barrier is at 7000. The FTSE 100 did not touch or go below 7000 at any point during the option’s life. Therefore, the barrier was *not* breached. 2. **Calculate Standard Call Option Payoff:** The FTSE 100 expired at 8200, and the strike price is 7800. The intrinsic value of a call option is calculated as: `Payoff = max(0, Spot Price at Expiration – Strike Price)` `Payoff = max(0, 8200 – 7800)` `Payoff = max(0, 400)` `Payoff = 400` 3. **Account for Option Premium:** The investor paid a premium of 50 for the option. The net profit is the payoff minus the premium: `Net Profit = Payoff – Premium` `Net Profit = 400 – 50` `Net Profit = 350` Therefore, the investor’s net profit is 350. Now, consider a different scenario: Suppose the FTSE 100 *had* briefly touched 6950 during the option’s life. Even if it rebounded to 8200 at expiration, the knock-out barrier would have been triggered, and the option would have expired worthless. The investor would have lost the entire premium of 50. This illustrates the significant risk associated with barrier options. Barrier options are often used in structured products to lower the cost of providing a specific payoff profile. For example, an investor might use a knock-out call option to gain leveraged exposure to the FTSE 100, but with the understanding that their upside is capped if the market experiences a significant downturn. This can be beneficial if the investor has a strong directional view but wants to limit their potential losses. However, it’s crucial to understand the “cliff edge” risk – the sudden and complete loss of the option’s value if the barrier is breached. This contrasts with a standard call option, where the investor only loses the premium if the underlying asset price is below the strike price at expiration.

The question tests the understanding of how different types of exotic options, specifically barrier options, are affected by market volatility and the specific structure of the barrier. A down-and-out call option becomes worthless if the underlying asset’s price hits the barrier level *before* the option’s expiration. Increased volatility raises the probability of the barrier being hit, thus decreasing the option’s value. The rebate is paid *only* if the barrier is breached. The rebate amount partially offsets the loss of the option’s intrinsic value when the barrier is hit. The initial value of the down-and-out call is calculated using a binomial or trinomial tree model, or Monte Carlo simulation, considering the barrier level, volatility, time to expiration, and rebate. Let’s assume, for simplicity, that the initial option value is £5. Now, consider the impact of increased volatility. With higher volatility, the probability of the underlying asset hitting the barrier increases. This reduces the value of the down-and-out call. Let’s say the volatility increase causes the option value to drop to £2. However, the rebate mitigates this loss. If the barrier is hit, the investor receives the rebate. The value of the rebate is contingent on the barrier being breached. The net effect on the investor’s position is the sum of the adjusted option value (due to volatility) and the expected value of the rebate. If the barrier is unlikely to be hit, the rebate has minimal impact. If the barrier is very likely to be hit, the rebate becomes a significant component of the position’s value. In this scenario, a £1 rebate provides some compensation for the loss in option value. The investor’s position is now worth £2 (remaining option value) + the expected value of the rebate. If the barrier is almost certain to be hit, the expected value of the rebate approaches £1. Therefore, the approximate value of the investor’s position is £3. The crucial point is that the rebate partially offsets the negative impact of increased volatility on the down-and-out call option.

Let’s break down this problem step-by-step. This question explores the interplay between implied volatility, time decay (theta), and the gamma of an option. We need to determine how these factors interact to affect the option’s price. First, consider the impact of the implied volatility decrease. A drop in implied volatility generally reduces the price of both call and put options because it reflects a decreased expectation of future price fluctuations in the underlying asset. This is because options derive their value from the potential for the underlying asset to move significantly. Second, theta, the time decay, is the rate at which an option’s value erodes as it approaches its expiration date. Theta is usually negative for options, meaning they lose value as time passes. However, the rate of decay accelerates as the option nears expiration. Third, gamma measures the rate of change of an option’s delta with respect to a change in the underlying asset’s price. Options that are at-the-money (ATM) have the highest gamma. A high gamma means the option’s delta is highly sensitive to price changes in the underlying asset. In this scenario, the option is ATM, meaning it has a high gamma. The implied volatility decreases, which lowers the option’s price. Simultaneously, the option is approaching expiration, so the theta (time decay) is accelerating, further reducing the option’s price. The high gamma means that even small changes in the underlying asset’s price could cause significant changes in the option’s delta. Since the implied volatility decrease already reduced the option price, and the time decay is accelerating, the combined effect is a notable decrease in the option’s value. Therefore, the value of the option will decrease more than if only one of these factors were at play. Let’s say the option was initially priced at £5. The volatility decrease might reduce it by £1, and the accelerated theta decay could reduce it by an additional £1.50. The combined effect results in a price decrease of £2.50. The high gamma magnifies the effect of any price changes, and the option value will decrease more than if only one of these factors were at play.

The question explores the concept of delta hedging a short call option position, focusing on the practical adjustments needed in a volatile market environment. Delta, representing the sensitivity of the option price to changes in the underlying asset’s price, is crucial for maintaining a hedged position. A short call option has a positive delta, meaning that as the underlying asset’s price increases, the option’s value also increases, resulting in a loss for the option writer. To hedge this, the option writer buys shares of the underlying asset. The number of shares to buy is determined by the delta. However, delta is not static; it changes as the underlying asset’s price fluctuates and as the option approaches its expiration date. This necessitates dynamic hedging, where the hedge is continuously adjusted to maintain a delta-neutral position. In a highly volatile market, large price swings can significantly alter the delta, requiring more frequent and substantial adjustments to the hedge. In this scenario, the fund manager initially establishes a delta hedge by buying 5,000 shares. When the underlying asset’s price increases, the delta of the short call option increases, meaning the option becomes more sensitive to further price increases. To maintain the hedge, the fund manager needs to buy additional shares. The new delta of 0.65 indicates that for every £1 increase in the underlying asset’s price, the option’s value will increase by £0.65 per share. To offset this, the fund manager needs to increase their long position in the underlying asset. The calculation is as follows: The delta increased from 0.50 to 0.65, a change of 0.15. This means the fund manager needs to buy an additional 0.15 shares for each option written. Since the fund manager wrote 100 contracts of 100 options each (10,000 options total), the additional shares required are 0.15 * 10,000 = 1,500 shares. Therefore, the fund manager needs to buy an additional 1,500 shares to rebalance the hedge. This ensures that the portfolio remains delta-neutral, mitigating the risk associated with the short call option position in a volatile market. This example illustrates the dynamic nature of delta hedging and the importance of continuous monitoring and adjustment in derivative strategies, especially when managing options portfolios.

Let’s break down how to value this bespoke Asian option and determine the closest approximation from the given choices. An Asian option’s payoff depends on the average price of the underlying asset over a specified period. This contrasts with standard European or American options, where the payoff is based solely on the price at expiry. Since we are dealing with discrete averaging and the path dependency of the average, a closed-form solution is generally unavailable. Therefore, we must use approximation methods. The most appropriate method here is Monte Carlo simulation. We simulate numerous possible price paths for the FTSE 100, calculate the average price for each path over the observation period (daily for 3 months), and then determine the option’s payoff for each path. The average of these payoffs, discounted back to the present, gives us an estimated option value. Here’s the conceptual approach: 1. **Simulate Price Paths:** Generate a large number (e.g., 10,000) of possible FTSE 100 price paths over the 3-month period, using a model like Geometric Brownian Motion. This model requires the risk-free rate (given as 5%) and the volatility (given as 20%). Each path will have daily prices. 2. **Calculate Average Price:** For each simulated path, calculate the arithmetic average of the daily FTSE 100 prices over the 3-month period. 3. **Determine Payoff:** For each path, the payoff of the Asian call option is max(Average Price – Strike Price, 0). The strike price is 7800. 4. **Discount Payoffs:** Discount each payoff back to the present using the risk-free rate. The discount factor for each path is \(e^{-rT}\), where \(r\) is the risk-free rate (0.05) and \(T\) is the time to maturity (3 months, or 0.25 years). 5. **Average Discounted Payoffs:** Average all the discounted payoffs. This average is the estimated value of the Asian option. Given the parameters (FTSE 100 at 7700, strike at 7800, 3-month maturity, 5% risk-free rate, 20% volatility), and recognizing that the FTSE 100 is currently below the strike price, the Asian option will likely have a lower value than a standard European option. The averaging effect reduces the volatility of the payoff. A reasonable estimate, considering these factors, is around £150. The other options are less likely: £50 is probably too low, given the volatility. £250 and £350 are likely too high because the current index level is below the strike price, and the averaging reduces the potential for large payoffs.

Let’s analyze the combined impact of margin requirements and the time value of money on the effective cost of a futures contract. We’ll consider a scenario involving a copper futures contract and illustrate how the opportunity cost of margin deposits influences the overall return. Suppose an investor enters a long copper futures contract at a price of £7,500 per tonne. The contract size is 25 tonnes, making the total contract value £187,500. The initial margin requirement is £9,000, and the maintenance margin is £6,500. The investor funds the margin account by liquidating a portion of their bond portfolio, which was yielding 4% annually. If the futures price rises to £7,700 per tonne after 90 days (approximately 0.25 years), the profit is (£7,700 – £7,500) * 25 = £5,000. However, we must account for the opportunity cost of the margin. The investor lost potential interest income on the £9,000 margin deposit. The opportunity cost is calculated as £9,000 * 0.04 * 0.25 = £90. This reduces the net profit to £5,000 – £90 = £4,910. Now, let’s examine the return on the initial margin. The return is £4,910 / £9,000 = 0.5456, or 54.56%. This demonstrates the leverage inherent in futures trading. Consider an alternative scenario where the investor had to deposit additional margin due to adverse price movements. If the price fell to £7,300 per tonne, the loss would be (£7,500 – £7,300) * 25 = £5,000. This would reduce the margin account balance to £9,000 – £5,000 = £4,000, below the maintenance margin of £6,500. The investor would need to deposit £2,500 to restore the initial margin level. The opportunity cost would then be calculated on the average margin balance over the 90 days. Furthermore, regulatory considerations, such as MiFID II, require firms to disclose all costs and charges associated with derivative transactions, including the impact of margin requirements and financing costs. This transparency helps clients make informed decisions and understand the true cost of trading derivatives. The FCA also mandates that firms assess the suitability of complex products like derivatives for retail clients, considering their knowledge, experience, and risk tolerance.

The question assesses the understanding of exotic derivatives, specifically barrier options, and their sensitivity to the underlying asset’s price movements in relation to the barrier level. The scenario involves a “knock-out” barrier option, where the option becomes worthless if the underlying asset’s price touches the barrier before the expiration date. To answer correctly, one must understand how the delta of a knock-out option changes as the underlying asset price approaches the barrier. Let’s consider a down-and-out call option. If the underlying asset price is far above the barrier, the option behaves similarly to a regular call option, and its delta is positive and relatively stable. However, as the underlying asset price approaches the barrier from above, the probability of the option being knocked out increases significantly. This causes the delta to decrease, eventually becoming negative as the price gets very close to the barrier. This is because a small upward movement in the underlying price increases the likelihood of the barrier being hit, thus decreasing the option’s value. Conversely, a small downward movement away from the barrier decreases the likelihood of being knocked out, thus increasing the option’s value. The concept can be analogized to a tightrope walker nearing the edge. Initially, their movements have a predictable impact on their stability. But as they get closer to the edge, even a small step towards the edge dramatically increases the risk of falling, making their balance increasingly sensitive to each step. In the case of a knock-out option, the “edge” is the barrier, and the “tightrope walker” is the underlying asset price. Therefore, the delta of a down-and-out call option decreases and can become negative as the underlying asset price approaches the barrier from above. This reflects the increased sensitivity of the option’s value to small price changes near the barrier.

The question assesses the understanding of exotic derivatives, specifically barrier options, and their sensitivity to volatility changes near the barrier. A down-and-out call option becomes worthless if the underlying asset’s price touches or falls below the barrier level. The closer the asset price is to the barrier, the more sensitive the option’s value becomes to changes in volatility. This is because increased volatility raises the probability of the barrier being hit, thus knocking out the option. We need to consider the combined effect of the asset price approaching the barrier and increased volatility. If the spot price is already near the barrier, a small increase in volatility dramatically increases the probability of the option being knocked out, causing a significant decrease in its value. A standard call option’s value generally increases with volatility, but for a down-and-out call near its barrier, the knock-out effect dominates. The magnitude of the decrease will depend on factors like the time to maturity and the specific barrier level relative to the current asset price. However, given the proximity to the barrier, the negative impact of increased volatility will be substantial. A down-and-out call option near the barrier is like a tightrope walker close to the edge. Even a slight gust of wind (increased volatility) dramatically increases the chance of them falling (the option being knocked out). Conversely, if the option were far from the barrier, the effect of volatility would be more similar to a standard call option. This question requires understanding the interplay between volatility, barrier proximity, and the knock-out feature of the exotic derivative. It also tests the ability to apply theoretical knowledge to a practical scenario.

The question assesses the understanding of exotic derivatives, specifically barrier options, and their behavior under different market conditions. A down-and-out call option becomes worthless if the underlying asset’s price touches or falls below the barrier level. The calculation involves understanding the probability of the barrier being hit before the option’s expiration. Let’s consider a scenario where a fund manager, Alice, wants to hedge her portfolio of tech stocks using a down-and-out call option. The current stock price is £100, and the barrier is set at £80. The option expires in 6 months. Alice believes there’s a significant chance the stock price might dip below £80 due to upcoming regulatory changes in the tech sector. If the barrier is breached, the option is extinguished, and Alice loses the premium paid. However, if the stock stays above £80 and rises, Alice benefits from the call option’s payoff. Now, imagine another fund manager, Bob, who is less risk-averse and believes the regulatory changes are already priced into the market. He might choose a standard call option without a barrier. If the stock price falls below £80 and then recovers, Bob still benefits from the potential upside. This highlights the trade-off: the down-and-out call is cheaper due to the barrier feature, but it carries the risk of becoming worthless if the barrier is hit. The decision depends on the investor’s risk tolerance, market outlook, and hedging strategy. The pricing of a barrier option is more complex than a standard option, as it involves estimating the probability of hitting the barrier. Models like Monte Carlo simulation are often used to estimate this probability and adjust the option’s price accordingly. The closer the barrier is to the current price, the higher the probability of it being hit, and the lower the option’s price.

Let’s consider a scenario where a UK-based agricultural cooperative, “Green Fields Co-op,” needs to hedge against fluctuating wheat prices. They are considering using futures contracts listed on the ICE Futures Europe exchange. Green Fields Co-op expects to harvest 5,000 tonnes of wheat in three months. The current futures price for wheat with a three-month expiry is £200 per tonne. The co-op wants to lock in a minimum selling price but also benefit if wheat prices rise. Therefore, they decide to implement a “fence” or “risk reversal” strategy using options on wheat futures. The co-op buys put options with a strike price of £190 per tonne to protect against a price decrease. This provides a floor for their selling price. Simultaneously, they sell call options with a strike price of £210 per tonne to partially offset the cost of buying the put options. This limits their potential profit if wheat prices rise significantly. The put options cost £5 per tonne, and the call options generate a premium of £3 per tonne. To calculate the effective price range, we need to consider the initial futures price, the strike prices of the options, and the net premium paid or received. Lower bound: If the futures price falls below £190, the put option will be exercised, guaranteeing a minimum selling price of £190. Considering the net premium received (£3 from selling calls minus £5 for buying puts = -£2), the effective lower bound is £190 – £2 = £188 per tonne. Upper bound: If the futures price rises above £210, the call option will be exercised, limiting the selling price to £210. Considering the net premium received (-£2), the effective upper bound is £210 – £2 = £208 per tonne. Therefore, the effective price range for Green Fields Co-op is between £188 and £208 per tonne. This fence strategy allows them to participate in some upside potential while protecting against significant downside risk. This is a common risk management strategy for agricultural producers who want to mitigate price volatility. The strategy’s effectiveness depends on accurately predicting price movements and understanding the costs and benefits of the options used. Regulations such as MiFID II would require the co-op to demonstrate that this strategy is suitable for their risk profile and investment objectives.

The value of a European call option is influenced by several factors, including the spot price of the underlying asset, the strike price, the time to expiration, the risk-free interest rate, and the volatility of the underlying asset. This question focuses on the combined impact of changes in volatility and time to expiration. According to options pricing theory, an increase in volatility generally increases the value of a call option because it increases the potential upside for the option holder. Similarly, an increase in time to expiration also generally increases the value of a call option, as it provides more time for the underlying asset to move favorably. However, the magnitude of these effects can vary. In this scenario, the volatility decreases from 25% to 20%, which, all else being equal, would decrease the option’s value. Simultaneously, the time to expiration increases from 3 months to 6 months, which, all else being equal, would increase the option’s value. To determine the overall impact, we need to consider the relative sensitivity of the option’s price to changes in volatility (vega) and time to expiration (theta). Since the decrease in volatility is substantial (20% relative change), and the time to expiration only doubles (100% relative change, but starting from a low base), the decrease in volatility is likely to have a greater impact than the increase in time to expiration. Therefore, the option’s value is most likely to decrease.

The correct answer involves understanding the combined effects of delta, gamma, and theta on a short call option position. Delta measures the sensitivity of the option price to changes in the underlying asset price. Gamma measures the rate of change of delta with respect to the underlying asset price. Theta measures the time decay of the option. In this scenario, the investor is short a call option, meaning they will profit if the option expires worthless or if the price of the underlying asset stays below the strike price. A negative delta (-0.40) indicates that if the underlying asset price increases, the option price will also increase, resulting in a loss for the short position. A positive gamma (0.05) indicates that as the underlying asset price increases, the negative delta will become less negative (moving towards zero), reducing the rate of loss. A negative theta (-0.03) indicates that the option loses value each day due to time decay, benefiting the short position. To determine the profit or loss, we need to calculate the change in the option price due to the change in the underlying asset price, adjust for gamma, and then account for theta. 1. **Delta Effect:** The underlying asset price increases by £2. The delta is -0.40, so the initial change in option price is -0.40 * £2 = -£0.80. This represents an initial loss of £0.80 per option. 2. **Gamma Effect:** The gamma is 0.05. This means that for every £1 increase in the underlying asset price, the delta changes by 0.05. Since the underlying asset price increased by £2, the delta changes by 0.05 * 2 = 0.10. The new delta is -0.40 + 0.10 = -0.30. The average delta during the £2 move is (-0.40 + -0.30) / 2 = -0.35. The change in option price due to delta, adjusted for gamma, is -0.35 * £2 = -£0.70. 3. **Theta Effect:** The theta is -0.03 per day. Over 5 days, the change in option price due to theta is -0.03 * 5 = -£0.15. This represents a profit of £0.15 per option. 4. **Total Profit/Loss:** The total change in the option price is the sum of the delta-adjusted change and the theta change: -£0.70 + (-£0.15) = -£0.55. Since the investor is short the option, a decrease in the option price results in a profit. Thus, the profit is £0.55 per option. For 100 options, the total profit is £0.55 * 100 = £55.

The question assesses the understanding of exotic derivatives, specifically a barrier option, and how its payoff is affected by the underlying asset’s price breaching a pre-defined barrier level. The problem requires calculating the payoff of a down-and-out call option, considering the spot price, strike price, barrier level, and whether the barrier was breached during the option’s life. First, determine if the barrier was breached. The barrier was set at 90, and the asset price touched 85 during the option’s life. Since 85 < 90, the barrier *was* breached. Because it is a "down and out" call option, the option is now worthless. Therefore, the payoff is 0. A regular call option gives the holder the right, but not the obligation, to buy an asset at the strike price. A barrier option adds another layer of complexity. In this case, a "down-and-out" call means the option only exists (has value) if the underlying asset price *doesn't* fall below the barrier. Imagine a steel manufacturer who only needs to hedge against rising iron ore prices if those prices stay above a certain level. If iron ore prices crash, their business is likely failing anyway, and the option is useless. Conversely, a "down-and-in" call option would *activate* if the price fell below the barrier. These are used in scenarios where hedging is only necessary if a price level is breached. The key to understanding barrier options is realizing their path dependency. The option's payoff isn't solely determined by the final asset price relative to the strike price, but also by the asset's price movement *during* the option's life relative to the barrier. This makes them cheaper than vanilla options, as there's a higher chance they'll expire worthless.

The question assesses understanding of swap valuation and the impact of credit risk. The swap’s value is the difference between the present values of the fixed and floating legs. The fixed leg’s present value is calculated by discounting each fixed payment by the appropriate discount factor (derived from the LIBOR curve). The floating leg’s present value is approximated by the next floating payment plus the notional amount, discounted back to the valuation date. Credit risk adjustment involves considering the probability of default by the counterparty and the potential loss given default. The expected loss is then subtracted from the swap’s value. First, calculate the present value of the fixed leg: Payment 1: £50,000 / 1.05 = £47,619.05 Payment 2: £50,000 / (1.05 * 1.06) = £44,830.43 Payment 3: £50,000 / (1.05 * 1.06 * 1.07) = £42,103.21 Payment 4: £50,000 / (1.05 * 1.06 * 1.07 * 1.08) = £39,432.84 Total PV of fixed leg = £47,619.05 + £44,830.43 + £42,103.21 + £39,432.84 = £174,000 (approx.) Next, calculate the present value of the floating leg: Floating payment = £55,000 PV of floating leg = (£1,000,000 + £55,000) / 1.05 = £1,004,761.90 Swap Value = PV of Fixed Leg – PV of Floating Leg = £174,000 – £1,004,761.90 = -£830,761.90 Credit Risk Adjustment: Expected Loss = Probability of Default * Loss Given Default Expected Loss = 0.02 * 0.40 * £1,000,000 = £8,000 Adjusted Swap Value = Swap Value – Expected Loss = -£830,761.90 – £8,000 = -£838,761.90
