Over on CAPS, fully 607 of the 642 members who have rated Alpha Natural -- some 94% -- believe the stock will outperform the S&P 500 going forward. These bulls include lloyd70mb and Jgrowth1.

Late last month, lloyd70mb tapped Alpha Natural as a natural turnaround play:

A real gem. ... Currently trading in the 12-14% range of last years high. I expect this stock to take off as oil increases in price this spring. [Alpha Natural] also has low long term debt and a favorable cash basis.

In a pitch from November, Jgrowth1 cited the company's cash position (which is even stronger today) as good reason to get involved:

First, they have approximately $600 million in the bank. So that means they have about $8.50 per share in cash. They still should generate good cash flows even in a slow economy. Coal contracts are pretty clean (no pun intended). ...

My opinion, [Alpha Natural] is undervalued and very attractively priced. Remember, the yield curve is very steep. Every central bank in the world is printing money like wild men. We could see a huge rebound in commodities and selling prices.
