A mutual fund’s “alpha” is not something that investors should obsess over. It is nothing more than the intercept of a linear-regression fit and when applied to investment portfolios, it is extremely noisy and unstable. Also, alpha doesn’t mean excess returns.

Do have a look at the website that updates the metrics discussed in the post here.
