trader accused of fraud says he wasn't acting as a rogue trader
when he lost $2.3 billion.  Kweku Adoboli took the stand for a
second day in his trial at London's Southwark Crown Court,
telling the jury the losses came after senior traders persuaded
him to change from a bearish to a bullish point of view in July
2011.  He testified Monday that he studied the market to "reduce
the number of things that are going to be surprises." But he
says that "if that is just a calculated gamble, then all
investment banking is a calculated gamble."  Prosecutors say
Adoboli lied, invented clients and breached safeguards against
high-risk trading to make money for the Swiss bank and boost his
bonus. He denies the charges.
