On CAPS, 97.5% of the 849 members who have rated Allis-Chalmers believe the stock will outperform the S&P 500 going forward. These bulls include llgrout and the sixth-ranked member in all of CAPS, UltraLong.

Just last week, llgrout tapped Allis-Chalmers' spill-effected shares as a slick opportunity: "Probably beaten down due to recent events in the gulf, it is at a bargain price right now. Earnings estimates are up going into next [fiscal year], so may have to hold on to it for a little while."

Over the past three months, Allis-Chalmers' stock has been slashed in half, while oilfield services behemoths Schlumberger and Halliburton are down about 10% during the same period. Of course, when you couple Allis-Chalmers' now cheapish forward P/E of 11 (Schlumberger and Halliburton sport forward P/Es of 15 and 14, respectively), with the fact that 60% of its revenue comes from overseas, it's easy to see why so many top-ranked Fools are high on the stock. CAPS All-Star UltraLong elaborates:

I don't often go this speculative in my long pick selection, but I can't turn down Allis-Chalmers Energy with it already trading well below its liquidation value. ... Gulf of Mexico revenue will be affected, but shouldn't be too detrimental to revenues. [Allis-Chalmers] is continually moving operations overseas so that should help to diversify their revenue stream. Short-term margins will be hurt, but long-term revenues will be more stable. Right now I see them trading around 10 times my 2012 EPS figures and as I said 0.55-0.60 times liquidation value. ...To me there's just too much value to overlook.
