Part 10 Attempt 1/1 What is the annual Sharpe ratio of a portfolio with 80% invested in the stock and 20% in the S&P 500? The T-bill yield is still 2%. Assume that the stock has an expected return of 12% and the S&P 500 of 7% (both EARS), and that the annualized variances and covariance stay the same as in the past. Hint: The covariance of returns over N weeks is N times the weekly covariance. Hint: Since we're looking at only one period (of one year), the distinction between rebalancing and not rebalancing is irrelevant here. 3+ decimals Save Part 11 What is the annual Sharpe ratio of the optimal risky portfolio? 3+ decimals Save Attempt 1/1
