over 8% of pxupa now owned by a hedge fund., page-4

My opinion, if PPX survives, then PXUPA at current price has a prospect of good (capital)returns, albeit perhaps over a longer period than many would want.
Tough for those who bought it at $40's, $50's and $60's, but at current less than $10, it looks like a no brainer - if your assessment is that PPX is going to either survive or be bought out.
