Market police deploy new weapons

London

THE day after the Federal Reserve raised interest rates, volume was so heavy on the Nordic stock exchanges that Joakim Strid's team of analysts identified 500 instances of possible fraudulent trading - and that was before lunch. "It's been a very busy morning," said Mr Strid, the head of European surveillance at Nasdaq Inc.

Mr Strid's Stockholm-based staff was keeping an eye on trading with Smarts, a software Nasdaq uses to unearth suspicious behaviour on 13 exchanges in Europe and the tech-driven exchanges it manages in the US.
