Professional portfolio managers calculate alpha as the rate of return that exceeds the model’s prediction, or comes short of it. They use a capital asset pricing model (CAPM) to project the potential returns of an investment portfolio. That is generally a higher bar.
An alpha generator is any security that, when added to an existing portfolio of assets, generates excess returns or returns higher than a pre-selected benchmark without additional risk. … New alpha generators can also occur from the expansion of investments into a new category.
Moreover, What is Alpha in CAPM?
Mathematically speaking, alpha is the rate of return that exceeds what was expected or predicted by models like the capital asset pricing model (CAPM). To understand how it works, consider the CAPM formula: r = Rf + beta * (Rm – Rf ) + alpha.
Secondly, What does a positive alpha mean in CAPM?
Alpha shows how well (or badly) a stock has performed in comparison to a benchmark index. Beta indicates how volatile a stock’s price has been in comparison to the market as a whole. A high alpha is always good.

What is alpha and beta in stock market?
Alpha and beta are two different parts of an equation used to explain the performance of stocks and investment funds. Beta is a measure of volatility relative to a benchmark, such as the S&P 500. Alpha is the excess return on an investment after adjusting for market-related volatility and random fluctuations.
How do you calculate market return in CAPM?

Rm = Expected return of the market. Note: “Risk Premium” = (Rm – Rrf) The CAPM formula is used for calculating the expected returns of an asset.
