What does R2/R-Squared measure?

A measure of the percentage of a funds movements that can be accounted for by changes in its benchmark index. An R-squared of 100 indicates that a funds movements are perfectly correlated with its benchmark. Thus index funds that invest only in S&P 500 stocks typically could have an R-squared close to 100. Conversely, a low R-squared indicates that little of the funds movements can be explained by movements in its benchmark index. An R-squared measure of 35, for example, means that only 35% of the funds movements can be explained by movements in the benchmark index. R-squared can be used to ascertain the significance of a particular Beta. Generally, a higher R-squared will indicate a more reliable Beta. If the R-squared is lower, then the beta is less relevant to the funds performance.
