Questions raised about whether the bets made by trader Iksil of the CIO at JP Morgan Chase were made to hedge risk, or to simply engage in proprietary trading for the bank in the hope of making large speculative profits. Bets made earlier by Iksil made large profits, but were simply speculative trades that increased bank profits. In late 2011 Iksil made a $1 billion bet that some companies would default on their debt in a few months. When American Airlines filed for bankruptcy protection Iksil's trades made about $450 million for Chase. But the trade had little to do with hedging risk.
