The Wall Street Journal reported on March 18, 2013 that U.S. Regulators, including the Commodity Futures Trading Commission (CFTC) and the Financial Industry Regulatory Authority (FINRA) are reviewing trading of high-frequency firms to determine if they are engaging in prohibited transactions, such as “wash” trades. The Article stated that the Regulators are reviewing records of primarily two exchanges, the CME Group, where the majority of wash trades have occurred, and the InterncontinentalExchange, Inc.
The Article identified that regulators are concerned that the exchanges do not have appropriate systems in place to identify or stop wash trades, especially in light of recent technical glitches leading to pronounced losses, including the Knight Capital Group and Facebook debacles in 2012.
Wash trades are when the same party places bids and asks for the same security, which causes there to appear increased activity in the security, which may affect its value, causing gains or losses to other investors who may be legitimately interested. In this way, a market participant manipulates the price of the security, prompting other participants to enter the market.
