A person is interested in constructing a portfolio. Two stocks are being considered. Letx = percent return for an investment in stock 1, and y = percent return for an investment instock 2. The expected return and variance for stock 1 are e(x) = 8.45% and Var(x) = 25.The expected return and variance for stock 2 are e(y) = 3.20% and Var(y) = 1. Thecovariance between the returns is sxy = −3.a. what is the standard deviation for an investment in stock 1 and for an investment instock 2? Using the standard deviation as a measure of risk, which of these stocks isthe riskier investment?

A person is interested in constructing a portfolio. Two stocks are being considered. Let
x = percent return for an investment in stock 1, and y = percent return for an investment in
stock 2. The expected return and variance for stock 1 are e(x) = 8.45% and Var(x) = 25.
The expected return and variance for stock 2 are e(y) = 3.20% and Var(y) = 1. The
covariance between the returns is sxy = −3.
a. what is the standard deviation for an investment in stock 1 and for an investment in
stock 2? Using the standard deviation as a measure of risk, which of these stocks is
the riskier investment?
