>My point was that if you call apple increasing over the course of 1 year, you might double your money if you're lucky. It's much more likely that the HFT operators will outperform you, as they have over the past decade.
These results don't seem related at all. You buy stock at price A and sell and price B (B = A+X, hopefully). What does it matter to you that other parties made money (perhaps more than X) while the stock was going to B? Institutional investors have always been more savvy about the market than retail ones. I don't see how them making money around the edges changes the calculus for "the rest of us."
