Mr. Gensler told a House hearing that federal regulators were closely examining the trading activity in the Standard & Poor’s 500 E-Mini futures contract, which is by far the largest stock index futures contract. Meanwhile, Mary L. Schapiro, the Securities and Exchange Commission’s chairwoman, said that “we recognize the pressing need to move rapidly” on the agencies’ investigation of the market plunge.
But Ms. Schapiro cautioned that the S.E.C. and the C.F.T.C. still had much work ahead of them. “We should recognize that it will take time to fully analyze the data,” she told the House Financial Services subcommittee on capital markets.
According to Mr. Gensler, the C.F.T.C. staff issued “special call” requests to 10 traders with the largest positions in the June 2010 S.& P. 500 E-Mini contract, requesting

The C.F.T.C. has learned that there were about 250 participants in the S.& P. E-Mini futures contract during the period when the market sold off. Of the 250, the agency is focused on the Top 10 largest longs and Top 10 shorts. Mr. Gensler said the majority of these traders traded on both sides of the market, meaning they both bought and sold during that period — acting, essentially, as liquidity providers.
But one of these accounts was using the E-Mini contract to hedge and only entered sell orders, meaning that the trader was betting that prices would fall.
“That trader entered the market at around
It is unusual for one trader to command such a large portion of a huge market like the S.& P. 500 E-Mini. Those futures contracts account for more than 80 percent of the notional value of American stock index futures open interest and trade on the CME Globex electronic trading system. This trader sold on the way down and continued to do so even as the price level recovered. It could be that this trader was actually a computer of some sort going haywire.
In later testimony, Terrence A. Duffy, executive chairman of the CME Group, which runs the Chicago Mercantile Exchange, questioned the role the E-Mini futures might have played in Thursday’s plunge. He told the House subcommittee that futures by design are meant to lead the market, so it was not unusual that the drop in the E-Mini futures occurred prior to when the stock market reached its lows.
“Futures contracts, by design, provide an indication of the market’s view of the value of the underlying stock index,” Mr. Duffy told the panel. “Casual observation may lead to the conclusion that the E-Mini S.&P. futures prices appeared to lead the decline in the cash market.”
Mr. Duffy noted that the cash (equity) market continued to fall when the Chicago Mercantile Exchange halted trading in the E-Mini for five seconds. The E-Mini rallied when trading resumed but some individual stocks continued to fall. After a few seconds the market corrected, following the E-Mini back up.
