Problem 3: Evaluating portfolio performance
Assume you have two investment opportunities.
1. Corporate Disasters (CD) has expected returns E(RcD) = 4% and standard deviation of
returns 9%.
2. Nevada beach front properties (NBF) has expected returns E(RygF) = 10% and standard
deviation of returns 18%
Risk free rate is R; = 1%.
a) Calculate Sharpe ratios of these two portfolios.
b) Assume you can invest only in one of those companies (and a risk free rate). Assume
your target rate of return is 6%. Calculate portfolios with CD&RF and NBF&RF which
would deliver this return. Which portfolio has smaller standard deviation and why?
c) Assume you have a portfolio which is not efficient. Assume Corporate Disasters have
market beta of ßep = 0.5 and Nevada beach front properties have market beta
BNef = 4. Calculate Treynor measures for those securities. Which one should you add to
your portfolio to increase the Sharpe ratio.
