A portfolio manager's portfolio earned 15% in a year, the risk-free rate was 6%, and the portfolio's standard deviation was 18%. What is its Sharpe ratio?

The Sharpe ratio is 0.50. Excess return over the risk-free rate is 9% (15% minus 6%), and dividing by the total risk of 18% standard deviation gives 0.50 of excess return per unit of total risk.

  1. A0.50Correct
  2. B0.83
  3. C0.33
  4. D1.50

Explanation

Sharpe ratio = (Rp − Rf) / standard deviation = (15 − 6) / 18 = 9/18 = 0.50. Using 15/18 ignores the risk-free rate and gives 0.83. The other values come from incorrect arithmetic.
