Examples of Alpha Formula (With Excel Template)
Let’s take an example to understand the calculation of the Alpha in a better manner.
Explanation of Alpha Formula
Firstly, determine the risk-free rate of return for the case. Typically, the annual yield of government bonds or treasury bills are considered to be risk-free and as such is used as the risk-free rate of return.
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.

Alpha is the difference between the returns of a stock vs the expected returns based on its Beta. If a stock has a high Beta value then it has more risk and so the expected returns are higher . If Alpha is zero then it is returning as expected. If Alpha is negative it is underperforming for its risk level.

Origin of Alpha
Capital Assets Pricing Model
- The CAPM is used to calculate the amount of return that investors need to realize to compensate for a particular level of risk. It subtracts the risk-free rate from the expected rate and weighs it with a factor – beta – to get the risk premium. It then adds the risk premium to the risk-free rate of return to get the rate of return an investor expects as compensation for the risk. The CAPM form…
Limitations of Alpha
- Alpha comes with a few limitations that investors should consider when using it. One of these limitations relates to various types of funds. Some investors use the ratio to compare different types of portfolios, such as portfolios that invest in different asset classes, and this can result in misleading numbers. The diverse nature of the different funds will affect metrics such as alpha. …

- Mathematically speaking, Alpha is the rate of return that exceeds a financial expectation. We will use the CAPM formula as an example to illustrate how Alpha works exactly: r = Rf + beta * (Rm – Rf) + Alpha Thus, Alpha = r – Rf – beta * (Rm – Rf) where: r = the security’s or portfolio’s return Rf = the risk-free rate of return beta = systemic risk ...
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…
