Can't tell if that is sarcasm or not, but in case it's not, SAC doesn't really trade illiquid holdings. They often own significant chunks (>5%) of stock in large companies, but this is in no way comparable to a Bears Stearns event. Bears' assets were illiquid, leveraged, and there were not enough buyers of the esoteric securities they were trying to get rid of. In the worst case scenario where SAC had to liquidate in a short time frame, they are doing so with the markets at peak levels and they trade mostly common stocks which are highly liquid. On top of that, they are not too leveraged, especially compared to banks and other hedge funds.
