An AI analyst made 30 years of stock picks – and outperformed human investors

This article doesn't mention what the yoy return is (bizarrely), but just buying the S&P 500 outperforms human investors, so just buying stocks randomly, which would have about the same expected return as buying the S&P would beat human investors. So as far as I can tell from the article, it might as well be buying randomly.

Fudging history is a lot easier than predicting the future.
