On CAPS, 97% of the 479 members who have rated Natural Gas Services believe the stock will outperform the S&P 500 going forward. These bulls include All-Stars dcrednek and Diagoras.

Last year, dcrednek listed several of the company's positives: "Very healthy operating margin, cash reserves exceed total debt. ... Given the strong and rising demand for natural gas, looks like NGS will be a solid bet to outperform a sideways moving market over the next several years."

Currently, Natural Gas Services even sports a cheapish price-to-cash flow of 7.5. That represents a clear discount to much larger energy service plays like Baker Hughes (33.9), Schlumberger (NYSE: SLB) (21.6), and Weatherford (NYSE: WFT) (14.9).

CAPS All-Star Diagoras expands on the outperform argument:

Right now, the ratio of oil price to natural gas price is at a relative high, and will likely fall given the various advantages of natural gas as a fuel coupled with increased de-hedging of natural gas production starting in 2012. This company, which fundamentally is fairly strong, should benefit from rising natural gas prices.
