IBM is piloting its Jeopardy-winning Watson technology as a tool for catching rogue traders at large financial institutions, executives said in an interview Monday. From a report: Referred to as Watson Financial Services, the new product will become a monitoring tool within companies to search through every trader's emails and chats, combining it with the trading data on the floor. The objective? To see if there are any correlations between suspicious conversations online and activity that could be construed as rogue trading.
