This is a good idea but the problem is the APIs for getting historical earnings data only work for a brief period of time before the fickle software developers change it or take it offline. I find that this is by far the biggest obstacle to writing financial software.

I will say though that a few years ago I wrote a simple script for valuing stocks using basically just the PE ratio with net assets factored in, and this resulted in me buying a stock that has more than doubled in value since I bought it in 2020. So I do think that it is possible to write software that beats the market without being a scholar of finance.
