Document Summary
Chapter 21 : 8,9,11 to 15,17 to 20,22 to 25,27,33 to 43: performance evaluation. Generally, the geometric average is preferable for calculation of historical returns while the arithmetic average is more appropriate for forecasting future returns. The concept of abnormal performance is critical to the process performance evaluation. As indicated above, it is more common to benchmark or market adjusted returns reported in industry. The measure of abnormal return using this risk-adjusted technique assumes the managed and the benchmark or market portfolio have the same level of risk. The market model or indexed model approaches are theoretically superior since they explicitly adjust for different levels of systematic risk. Factors that lead to superior performance include selection of undervalued stock and the ability to time general movements in the market. The sharpe measure is also widely accepted in industry. The slope measure is based on the portfolio risk premium and the total risk of the portfolio as measured by standard deviation.
