Cool website. Percentage is a good place to start, but if you want to get closer to the alpha of a given idea, dividing the percentage return by its beta to the benchmark, then subtracting the return of the benchmark over the same period will get you closer.

I did consider beta adjusting performance and may do this in the future -- it does require more infra set up (ex. computing historical betas for these posts back in time).

Since my target demographic in this case was people on Reddit following trading advice I wanted to keep things straightforward first and slowly over time introduce those educational components to get it closer to how the industry thinks about it.

I find this formula unintuitive (for starters I had to google what alpha and beta was). Does it have a name so I can look it up?
