The question every budding trader should ask themselves, according to Société Générale, is: "Are you a superhero or a supervillain?"

The French bank today kicks off a four-week competition in real-time virtual warrant trading, promising great prizes to the top performers. Players will have £10,000 of pretend money to trade each week. The winner will walk away with a state-of-the-art plasma TV, while the rest of the top five players will receive the more serious-minded prize of an annual subscription to a financial website. And for those lower down the rankings? An SG cycling top and a pair of sgwarrants.com rugby shorts, as worn by the Saracens rugby team. Village reckons the question every trader should be asking is: "When was the kit last washed?"
