Frequent increasing positions and leverage are not very friendly to retail investors, as small orders generally yield about 1% profit, but switching positions often incurs a 0.1% slippage, plus a 10% dividend. One-tenth of the profit goes to slippage, one-tenth goes to the big players, leaving less than 80% of the profit for retail investors. Retail investors need to have positions about 20% higher than the big players to barely ensure that their daily earnings, after accounting for these losses, are on par with the big players. However, on the other hand, this is still because they lack the ability to trade independently and rely on following others, making some profit is enough.
