Since Cramer has a large audience, his picks function as a magnet that aligns the beliefs of some subset of that audience. If the effect is large enough, then trading against that effect can be worthwhile. It's exploiting the same alignment effect as companies that buy order flow from retail investor apps. Retail investors typically do not generally buy large amounts of a single stock over time to get the best price. By buying Robinhood's order flow, Citadel can trade against a counterparty whose behavior is generally known. The theory behind exploiting the gradient created by alignments caused by factors other than fundamental business performance is better than random.
