Attempt 1/1 Part 10 What is the annual Sharpe ratio of a portfolio with 60% invested in the stock and 40% in the S&P 500? The T-bill yield is still 2%. Assume that the stock has an expected return of 14% and the S&P 500 of 5% (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 Attempt 1/1 Part 11 What is the annual Sharpe ratio of the optimal risky portfolio? 3+ decimals Save Intro You must complete this assignment in the next 2 hours.
