TradingSports Exchange Systems, the Aim-listed betting systems group, improved 1p to 72 1/2p. It launched BetonSports, where punters bet against each other rather than with a bookmaker, at the weekend to coincide with the Super Bowl. It handled more than £980,000 of match bets on that game alone and signed up 500 customers. Evolution says buy and has a target price of 100p.
