That's a couple months old, was posted before, and is as of 3/31/09. Goldman just announced a big 2nd quarter profit based on huge trading profits so Goldman obviously knows how to trade.
It will speak volumes how much holdings Goldman still has of Chemtura at end of June, considering this went to .48. But then again don't know at what prices Goldman bought in, but based on their trading acumen I would not be surprised if they increased it after Chemtura filed for Bankruptcy.
