‘Siri, catch market cheats’: Wall Street watchdogs turn to A.I.

Artificial intelligence programs have beaten chess masters and TV quiz show champions. Next up: stock market cheats.

Two exchange operators have announced plans to launch artificial intelligence 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.

A.I. may even sniff out new types of chicanery, said Tom Gira, executive vice president for market regulation at the Financial Industry Regulatory Authority (FINRA).

“The biggest concern we have is that there is some manipulative scheme that we are not even aware of,” he told Reuters. “It seems like these tools have the potential to give us a better window into the market for those types of scenarios.”

FINRA plans to test artificial intelligence software being developed in-house for surveillance next year, while Nasdaq Inc (NDAQ.O) and the London Stock Exchange Group (LSE.L) expect to use it by year-end.

The exchange operators also plan to sell the technology to banks and fund managers, so that they can monitor their traders.
