The portfolio has proved to be riskier

"The portfolio has proved to be riskier, more cheap burberry outlet online and less effective as an economic hedge than we thought," CEO Jamie Dimon told reporters. "There were many errors, sloppiness and bad judgment." RELATED: Stock market tumbling? Four ways to control your risk. The trading loss is an embarrassment for a bank that came through the 2008 financial crisis in much better health than its peers. It kept clear of risky investments that hurt many other banks. The loss came in a portfolio of the complex financial instruments known as derivatives, and in a division of JPMorgan designed to help control its exposure to risk in the financial markets and invest excess money in its corporate treasury. Bloomberg News reported in April that a single JPMorgan trader in London, known in the bond market as "the London whale," was making such large trades that he was moving prices in the $10 trillion market. Dimon said the losses were "somewhat related" to that story, but seemed to suggest that the problem was broader. Dimon also said the company had "acted too defensively," and should have looked into the division more closely. The Wall Street Journal reported last month that JPMorgan had invested heavily in an index of burberry sunglasses credit-default swaps, insurance-like products that protect against default by bond issuers. Hedge funds were betting that the index would lose value, forcing JPMorgan to sell investments at a loss. The losses came in part because financial markets have been far more volatile since the end of March. Partly because of the $2 billion trading loss, JPMorgan said it expects a loss of $800 million this quarter for a segment of its business known as corporate and private equity. It had planned on a profit for the segment of $200 million. The loss is expected to hurt JPMorgan's overall earnings for the second quarter, which ends June 30. Dimon apologized for the losses, which he said occurred since the first quarter, which ended March 31. "We will admit it, we will learn from it, we will fix it, and we will move on," he said. Dimon spoke in a hastily scheduled conference call with stock analysts. Reporters were allowed to listen. Among other bank stocks, Citigroup was down 3.3 percent in after-hours trading, Bank of America was down 2.9 percent, Morgan Stanley was down 2.4 percent, and Goldman Sachs was down 2.2 percent. JPMorgan is trying to unload the portfolio in question in a "responsible" manner, Dimon said, to minimize the burberry bags yellow beige 2012 fashion discount cost to its shareholders. Analysts said more losses were possible depending on market conditions.
