In the spring of 2012, JPMorgan Chase & Co.'s (NYSE: JPM) not-so-rogue trader, Bruno Iksil, better known as the London Whale, made a series of derivatives trades on credit default swaps that only appeared to be unauthorized.
In reality, those trades were just one side of JPMorgan betting against the other in a doom struck hedging strategy.
We're talking about trades so big they made waves across a $10 trillion market.
