The commons converted to JPM commons on a one-to-one basis, we all sell in the 40.00's, the stock takes a hit anyway due to the dilution, then we all use our gigantic proceeds from our sales, to massively short the ever-loving bejeesus outta JPM, thus crashing them big-time and causing the largest bear-raid in history. This causes a massive run on deposits as customers get wind of JPM's shaky financial situation, the FDIC steps in and seizes them because they are a significant risk to the system, and sells them to Goldman for a penny on the dollar.
That would be karma of the finest sort.
