Relevance and Uses
From the perspective of a portfolio analyst, the concept of alpha is very important as it is used to assess the ability of a portfolio manager to generate a risk-adjusted return. Alpha is the excess return generated vis-à-vis the risk of the portfolio and it is purely seen as the portfolio manager’s credit.

How does capital asset pricing work?
The Capital Assets Pricing Model calculates what return investors need to compensate for a specific level of risk. It defines a risk-free rate of return Krf, usually the rate on U.S. government Treasury bonds, and an expected rate of return Km. It subtracts the risk-free rate from the expected rate and weights it with a risk factor Beta to get a risk premium. It adds the risk premium to the risk-free rate of return to get Ks, the rate of return an investor requires as compensation for the risk.
What do stock market analysts do?

First Market Scenario
- The excess returns on the fund are plotted against the excess returns on the market as shown above. The regression line in the first scenario has a positive intercept. This is the abnormal performance. Interpretation:the funds (represented as dots) above the line performed better than the market.
Second Market Scenario
- The second scenario shows what is known as market timing. If the portfolio manager knows when the stock market is going up, s/he will shift into high beta stocks. If the portfolio manager knows the market is going down, he will switch to low beta market. In the high beta stocks, these stocks will go up even further then the market and in the case of low beta stocks, these stocks …
Third Market Scenario
- The third scenario assumes that the fund manager has an outstanding sense of market timing as in this case his portfolio does not have negative returns at all. In this case, the fund goes up by more than the market, yet the Jensen measure/Alpha, in this case, is negative. Even though the manager has shown strong market timing skills, the performance evaluation criterion reveals th…
