JP Morgan Derivative/Props Desk 3+ Billion Losses. WHY did they release this info on a Thursday after market not Friday after market, as normal bad financial news is? Worse news to come?

UPDATE 5/17/12 - here is what I was looking for- the bigger story that was revealed last week that needed to be covered up immediately, in my opinion. Naked Illegal Short Selling by Goldman Sachs.

Update 5/21/12 - JPM losses eclipse 30+ Billion including stock value loss.
