re: EXXI - hitting new lows everyday

We watched a video on the housing bubble in my finance class at LSU, and it had a small bit in Bass. It talked about how he purchased insurance on mortgage backed securities after he figured out the crash was coming. Forgot exactly how much he made on that, but I remember hearing something like 600% ROI. So what's his play on this now? This stock is nose diving today.

Eta: Here's that video I was talking about. It's a bigger documentary, but here is the section on Bass. LINK
