Yasmin is a mean-variance optimising investor with risk-aversion A = 2. She has 100 to invest. There are two stocks that Yasmin can choose for her investment portfolio. The first stock has an expected return of 14% with a standard deviation of 20%. The second stock has an expected return of 8% with a standard deviation of 10%. The returns on the two stocks have a correlation coefficient of = 0.75 ANSWER QUESTION B Now suppose Yasmin can invest in both stocks. Construct the optimal portfolio of the two stocks, i.e. work out the mean-variance maximisation problem maxw{E[Rp]21Ap2} for a portfolio p consisting of stock 1 and stock 2. How should Yasmin optimally allocate her budget of 100 ? [22pts].

1. Yasmin is a mean-variance optimising investor with risk-aversion A = 2. She has 100 to
invest. There are two stocks that Yasmin can choose for her investment portfolio. The first
stock has an expected return of 14% with a standard deviation of 20%. The second stock has
an expected return of 8% with a standard deviation of 10%. The returns on the two stocks
have a correlation coefficient of = 0.75.
(a) Suppose Yasmin can only invest in one of the two stocks. Should she choose stock 1 or
stock 2?
