Look on the bright side.....if you're long in the market and they catch Bin Laden, you're laughing.......

If something contrary to your position, long or short, happens; you just have to hope that your stop-loss is tight and gets filled promptly (which is in doubt if the market 'spikes' in either direction... )

edit - and if your position is 'in the money' use a trailing-stop to protect profits.
