JP Morgan 'loss' - too much ado about nothing?

The reported 'loss' that JP Morgan took on its investment account may appear to be large but in the context of a portfolio size of $ 300+ billion and a total balance sheet of more than $ 2000 billion it really is small beer. Every investor or trader worth his salt will know that no investment goes up in a straight line. Daily fluctuations of one percent are the norm. That would mean that the investment book could be up or down three billion dollars on any given day. Hedging is no panacea. If you fully hedge all risk out of a portfolio you may as well stay in treasury bills as the cost of the hedge will eat up all the expected profit. I am sure that some aspects of the portfolio could probably have been handled better but loan books - even surrogate ones - are usually meant to be held to maturity so the mark-to-market loss should not have been of any consideration. That various busy-bodies (media, various officials like the department of justice or the New York Auditor) should feel competent to be backseat drivers for JP Morgan's investment department adds a twist of absurdity to the whole affair. Jamie Dimon also made a mistake to preemptively excuse himself in front of a baying media crowd rather than calmly explain the realities of the investment game.
