Answer: USD 23,316
## Explanation To calculate the maximum possible daily 95% VaR, we need to consider the worst-case scenario for portfolio diversification, which occurs when the correlation between the two funds is +1 (perfect positive correlation). ### Step 1: Calculate daily volatilities - Alpha daily volatility = 20% / √252 = 20% / 15.8745 = 1.2599% - Omega daily volatility = 25% / √252 = 25% / 15.8745 = 1.5749% ### Step 2: Calculate portfolio weights Since the portfolio is equally invested: - Weight in Alpha = 0.5 - Weight in Omega = 0.5 ### Step 3: Calculate portfolio volatility with ρ = +1 When correlation is +1, portfolio volatility is simply the weighted sum: σ_portfolio = w₁σ₁ + w₂σ₂ = 0.5 × 1.2599% + 0.5 × 1.5749% = 1.4174% ### Step 4: Calculate daily 95% VaR Given μ = 0 (as specified), and using z-score for 95% confidence level = 1.645: VaR = Portfolio Value × σ_portfolio × z-score VaR = 1,000,000 × 1.4174% × 1.645 = 1,000,000 × 0.014174 × 1.645 = USD 23,316 ### Verification The maximum possible VaR occurs when correlation is +1 because there is no diversification benefit. If correlation were less than +1, the portfolio volatility would be lower, resulting in a smaller VaR. Therefore, the maximum possible daily 95% VaR is **USD 23,316**.

Consider a USD 1 million portfolio with an equal investment in two funds, Alpha and Omega, with the following annual return distributions:
| Fund | Expected Return | Volatility |
|---|---|---|
