I am curious why unusual whales did not compare performance to market performance over set periods. I looked around for some papers and was unable to find anything recent. CATO published a report showing there is weak performance difference between senators and their stock portfolio [1]. If they are outperforming this should 100% be remedied but I'd be open if anyone has comments that would contradict this report?
