About $US2 billion was lost by JPMorgan Chase, US’ largest bank, in a trading portfolio, according to the company. The same portfolio was designed to protect the company against the risks it takes in relation to its money.

After the loss was announced on Thursday, a plunge of more than 6 percent in the company’s stocks in the late electronic trading was recorded. It was not only the JPMorgan Chase that felt the losses. Other companies also felt the same like Citigroup and the Bank of America.
