If the above is true, why would a fund not just allocate a small amount of resources to trade on OP's strategies. Either:
(1) OP's strategy performs worse than the alternative
(2) They already do this, and have resources that allow them to outperform OP at their own strategy
If the returns are really meaningful, i.e. better Sharpe ratio than just holding $SPY or some dead simple strategy like that, then (2) must be true at least _somewhere_.
