An alpha of less than 0 indicates that the investment returned less than the benchmark, adjusted for their respective volatility. R-squared R 2 is a method an investor or analyst can use to see how well alpha and beta capture the relationship between the return on a security and the return on the overall market.
R 2 is also called the coefficient of determination, or the proportion of the variation in the security's return that is determined by the market return given the estimated values of alpha and beta. As an investor, you want to know how your holding is doing over time against the benchmark index shown by the size of alpha and beta , but you also want to know how reliable the relationship expressed by alpha and beta is between that security and the overall market.
R 2 defines the practical value of alpha and beta on a scale from 0 to 1. A high R-squared number from. A low R 2 anything below. Instead the returns on the security may be more random, or may be explained by unobserved factors other than the market index return. You can determine R 2 by using a standard formula. Some mutual fund companies report the R 2 of their funds in their advertising literature, but others do not.
Yahoo Finance and Morningstar calculate and publish R 2 data as well as beta figures daily. In general, investments with a high beta reading are seen as relatively risky. Stocks with a high beta will tend to rise more quickly than their benchmarks in bull markets and fall more quickly in bear markets. However, one should also consider R 2 , because it indicates the reliability of alpha and beta, because high or low beta with a low R 2 may not be all that meaningful, or may even be deceptive to the unwary.
On the other hand a high R 2 suggests that the given estimates of alpha and beta should be taken more seriously. Tools for Fundamental Analysis. Investing Essentials. Risk Management.
