JPMorgan Reaped Up to $300 Million Gain On Swiss-Franc Turmoil

``The bank netted $250 million to $300 million on the day of the Swiss National Bank's surprise decision to scrap the franc ceiling of 1.20 against the euro, said the people, who asked not to be identified because they weren't authorized to speak publicly. A JPMorgan spokesman declined to comment. The SNB's surprise decision on Jan. 15 to remove the three-year-old cap sent the franc soaring as much as 41 percent against the euro that day. JPMorgan is one of the few to emerge from the turmoil with a profit.''
