Suppose that the S&P 500, with a beta of 1.0, has an expected return of 11% and T-bills provide a risk-free return of 6%.
a. What would be the expected return and beta of portfolios constructed from these two assets with weights in the S&P 500 of (i) 0; (ii) 0.25; (iii) 0.50; (iv) 0.75; (v) 1.0? (Leave no cells blank - be certain to enter "0" wherever required. Do not round intermediate calculations. Round your answers to 2 decimal places.)
b. How does expected return vary with beta?
