Help me understand Alpha and Beta

[dinorocks]

To my naive eyes, it looks like Alpha and Beta aren't calculated correctly. I did a test where I just buy and hold the equity, and the Beta (which should measure correlation to the underlying) was basically 0 (0.02) and Alpha was some large number proportional to my total return %. I would think that just buy and hold would result in a Beta close to 1, and an Alpha close to 0, but maybe I'm not understanding this correctly?

I see on the README.md, the example also shows this phenomenon.

Any answers are much appreciated
