CHK had a market cap of about $4B as recently as 18 months ago when it was struggling with a huge amount of debt and reporting losses .... so you'd think it should be at least $4B now given that over 85% of the debt has been eliminated, though I believe some properties were spun off as part of the restructuring so production will be lower.
So if the stock starts trading at $40 tomorrow, implying a market cap of $4B, then I'll probably pick up a few shares and then see how it trades.
