On CAPS, 95% of the 437 members who have rated GMX believe the stock will outperform the S&P 500 going forward. These bulls include DannyNOLA and Charlie1368.

Late last year , DannyNOLA tapped GMX as a natural selection:

Currently, we have a huge natural gas excess supply and a crappy economy, but I think over the long term natural gas will play a bigger role. [GMX] is cheap and small so I am hoping one of the bigger players is willing to buy it soon while natural gas prices are still dirt cheap.

In fact, GMX currently trades at a paltry price-to-book of 0.5. That represents a clear discount to competitors BP (1.6), Cabot Oil & Gas (2.3), and Southwestern Energy (4.4).

CAPS member Charlie1368 elaborated in December on the bargain opportunity:

GMX Resources has amassed a body of assets that give it a solid competitive moat for at least the next few years. Trading at a discount to these assets which can produce long-term earnings potential, GMX Resources is a great value. Add in a decent balance sheet, solid cash flow, lots of insider buying, and bullish options sentiment, and you have a great buy.
