J.P. Morgan's $2 billion blunder

The bank, betting on a continued economic recovery with a complex web of trades tied to the values of corporate bonds, was hit hard when prices moved against it starting last month, causing losses in many of its derivatives positions. The losses occurred while J.P. Morgan tried to scale back that trade.

The bank’s strategy was “flawed, complex, poorly reviewed, poorly executed and poorly monitored,” Mr. Dimon said Thursday in a hastily arranged conference call with analysts and investors after the stock-market close. He called the mistake “egregious, self-inflicted,” and said: “We will admit it, we will fix it and move on,” he said.

The CEO emphasized that the bank remains profitable despite the trading loss. “While we don’t give overall earnings guidance and we are not confirming current analyst estimates, if you did adjust current analyst estimates for the loss, we still earned approximately $4 billion after-tax this quarter give or take,” he said on the call. The bank earned $5.38 billion in the first quarter.
