'Siri, catch market cheats': Wall Street watchdogs turn to artificial intelligence - The Economic Times

NEW YORK: Two exchange operators have announced plans to launch artificial intelligence (AI) tools for market surveillance in the coming months and officials at a Wall Street regulator tell Reuters they are not far behind. Executives are hoping computers with humanoid wit can help mere mortals catch misbehavior more quickly. The software could, for instance, scrub chat-room messages to detect dubious bragging or back slapping around the time of a big trade. It could also more quickly unravel complex issues, like "layering," where orders are rapidly sent to exchanges and then canceled to artificially move a stock price. AI may even sniff out new types of chicanery, said Tom Gira, executive vice president for market regulation at the Financial Industry Regulatory Authority (FINRA).
