Chicago Mercantile Exchange (CME) used to be the greatest thing since sliced bread for the bulls. It climbed about 1,000% from the end of 2003 to the end of 2007.
Since then, it's been a free-fall. I wish I could say I had a position on this, but I don't; I haven't traded it in a while. But it's a spectacle, and evidence of what kind of damage can befall a highflier.
