High-Speed Trades Hurt Investors, a Study Says

The chief economist at the Commodity Futures Trading Commission, Andrei Kirilenko, reports in a coming study that high-frequency traders make an average profit of as much as $5.05 each time they go up against small traders buying and selling one of the most widely used financial contracts.

The agency has not endorsed Mr. Kirilenko’s findings, which are still being reviewed by peers, and they are already encountering some resistance from academics. But Bart Chilton, one of five C.F.T.C. commissioners, said on Monday that “what the study shows is that high-frequency traders are really the new middleman in exchange trading, and they’re taking some of the cream off the top.”

Mr. Kirilenko’s work stands in contrast to several statements from government officials who have expressed uncertainty about whether high-speed traders are earning profits at the expense of ordinary investors.

The study comes as a council of the nation’s top financial regulators is showing increasing concern that the accelerating automation and speed of the financial markets may represent a threat both to other investors and to the stability of the financial system.

The Financial Stability Oversight Council, an organization formed after the recent financial crisis to deal with systemic risks, took up the issue at a meeting in November that was closed to the public, according to minutes that were released Monday.

The gathering of top regulators, including Treasury Secretary Timothy F. Geithner and Ben S. Bernanke, the Federal Reserve chairman, said in its annual report this summer that recent developments “could lead to unintended errors cascading through the financial system.” The C.F.T.C. is a member of the oversight council.

The issue of high-frequency trading has generated anxiety among investors in the stock market, where computerized trading first took hold. But the minutes from the oversight council, and the council’s annual report released this year, indicate that top regulators are viewing the automation of trading as a broader concern as high-speed traders move into an array of financial markets, including bond and foreign currency trading.

Mr. Kirilenko’s study focused on one corner of the financial markets that the C.F.T.C. oversees, contracts that are settled based on the future value of the Standard Poor’s 500-stock index. He and his co-authors, professors at Princeton and the University of Washington, chose the contract because it is one of the most heavily traded financial assets in any market and is popular with a broad array of investors.

Using previously private data, Mr. Kirilenko’s team found that from August 2010 to August 2012, high-frequency trading firms were able to reliably capture profits by buying and selling futures contracts from several types of traditional investors.

The study notes that there are different types of high-frequency traders, some of which are more aggressive in initiating trades and some of which are passive, simply taking the other side of existing offers in the market.

The researchers found that more aggressive 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.

Industry profits have been falling, however, as overall stock trading volume has dropped and the race for the latest technological advances has increased costs.
