A portfolio has a correlation of 0.40 with the overall market and produces a Sharpe Ratio of 0.2. If the market's volatility is 20%, what is portfolio's *Trevnor ratio* ?

Consider a long-short portfolio. Beta of this portfolio is zero and its volatility is 20% . What is the portfolio-specific (unsystematic) variance of this portfolio

Suppose risk-free rate of return = 2%, market return = 7%, and Stock B’s return = 11%. Calcuate Stock B’s beta. If Stock B’s beta were 0.80, what would be its new rate of return?

Assume the CAPM holds and consider stock X, which has a return variance of 0.09 and a correlation of 0.75 with the market portfolio. The market portfolio's Sharpe ratio is 0.30 and the the risk-free rate is 5%. (a) What is Stock X's expected return? (b) What proportion of Stock X's return volatility (i.e. standard deviation) is priced by the market? Explain why this number is less than 1.

Suppose the risk free rate is 5% and the market portfolio has an expected return of 10%. Portfolio Z has a correlation coefficient with the market of 0.1 and a variance of 0.16. The market portfolio has a variance of 0.09. According to the CAPM, what is the beta of portfolio Z?

What must be the beta of a portfolio with E(rP) = 18%, if rf= 6% and            E(rM) = 14%?

E(FAssume that using the Security Market Line (SML) the required rate of return (RA) on stock A is found to be half of the required return (Rs) on stock B. The risk-free rate (R;) is one-fourth of the required return on A. Return on market portfolio is denoted by RM. Find the ratio of beta of A (BA) to beta of B (BB). a o
