Here are the performance of the three external funds that are run by Renaissance Technologies (the father of AI/ML investing). Despite the fact that Renaissance Technologies employs more than 100 PhDs and equipped with high- end supercomputers. All three funds underperform the market by a signficant margin.
Just want to point out that AL/ML is not an automatic ticket to out-of-sample performance (especially without basic cross validation/walk forward - The impact of overfitting multiples by 10 folds with AI/ML.)
