The researchers found that more aggressive high frequency traders accounted for the largest share of trading volume and made the biggest profits. The most aggressive scored an average profit of $1.92 for every futures contract they traded with big institutional investors, and made an average $3.49 with a smaller, retail investor. Passive traders, on the other hand, saw a small loss on each contract traded with institutional investors, but they made a bigger profit against retail investors, of $5.05 a contract.
Large investors can trade thousands of contracts at once to bet on future shifts in the S.& P. 500 index. The average aggressive high-speed trader made a daily profit of $45,267 in a month in 2010 analyzed by the study.
