Problem 18-02 An analyst wants to evaluate Portfolio X, consisting entirely of U.S. common stocks, using both the Treynor and Sharpe measures of portfolio performance. The following table provides the average annual rate of return for Portfolio X, the market portfolio (as measured by the Standard and Poor's 500 Index), and U.S. Treasury bills (T-bills) during the past eight years. Portfolio X S&P 500 T-bills n/a = not applicable Annual Average Rate of Return Portfolio X S&P 500 Based on the Treynor measure Portfolio X-Select- measure for the S&P 500. 11% 13 6 Based on the Sharpe measure Portfolio X-Select- for the S&P 500. Standard Deviation of Return 19% 16 a. Calculate both the Treynor measure and the Sharpe measure for both Portfolio and the S&P 500. Round your answers for the Treynor measure to one decimal place and for the Sharpe measure to three decimal places. Treynor measure Sharpe measure n/a % % Beta 0.40 1.00 n/a Briefly explain whether Portfolio X underperformed, equaled, or outperformed the S&P 500 on a risk-adjusted basis using both the Treynor measure and the Sharpe measure. the market index because Treynor measure for Portfolio X is-Select-than Treynor the market index because Sharpe measure for Portfolio X is-Select-than Sharpe measure b. Based on the performance of Portfolio X relative to the S&P 500 calculated in Part a, briefly explain the reason for the conflicting results when using the Treynor measure versus the Sharpe measure. As Treynor measure considers -Select- risk while Sharpe measures considers -Select- risk so a -Select- diversified portfolio could show better performance relative to the market if the Treynor measure is used but lower performance relative to the market if the Sharpe measure is used. As a result, Portfolio X has a large amount of -Select- risk
