On November 3, 2015, an Illinois federal jury convicted Michael Coscia, a high-frequency commodities trader, of six counts of commodities fraud and six counts of spoofing—entering a buy or sell order with the intent to cancel before the order’s execution. Coscia’s conviction was the first under the criminal anti-spoofing provisions added to the Commodity Exchange Act (CEA) by the 2010 Dodd-Frank Wall Street Reform and Consumer Protection Act. In the press release touting its victory, the prosecution announced: “The jury’s verdict exemplifies the reason we created the Securities and Commodities Fraud Section in Chicago, which will continue to criminally prosecute these types of violations.” High-frequency traders should take note that the conviction on all six counts of spoofing charged in Coscia’s case may embolden prosecutors across the nation to pursue other spoofing cases with vigor. Given the real possibility of a felony indictment and conviction for spoofing—the latter of which exposes a defendant to imprisonment for up to ten years and significant monetary fines—high-frequency traders should carefully evaluate their strategies and conduct.
