Thanks! The data is being pulled directly from Yahoo Finance. GitHub Actions runs the grading algorithm automatically weekly during earnings season, and monthly otherwise.
Yeah, COWZ is essentially doing this at the fund level. The difference here is seeing individual company grades and balance sheet breakdowns behind each one rather than just holding the big basket.
Mostly to see through company earning manipulation.Not making a direct claim that the A grades will outperform, that'll need backtesting that I haven't done yet but will attempt to do. Its more of a fundamental health screener than a trading signal.
AWS alone would probably be an A but you can't separate them in the cash flow statement. Take away the retail aspect and it would be a different story.
