The winner algorithm is short live. I.e. to be a winner in the stock market, you must have a loser that took the other side. Since the marginal trade is done by sophisticated players, as soon as they realized that they are losing, they will either stop trading or switch algorithms. This would render the winning algorithm as ineffective. Note that buffet succeeded in a different market (1970), today buffet mainly run companies, not trade. Also, HFT today are about providing liquidity, not trading.
