On CAPS, 98% of the 462 members who have rated GulfMark believe the stock will outperform the S&P 500 going forward. These bulls include Ritio and Fool Rising Star Jason Moser (TMFJMo).

Just last week, Ritio tapped GulfMark as a particularly slick selection: "As relief in the gulf occurs, the safer way of looking for resources should give a positive aspect to our future in [A]merica with oil. ... [F]or the time at hand this stock is sure to show promising results."

Thanks to its young fleet of offshore support vessels and cheapish valuation, GulfMark is becoming an increasingly popular deepwater drilling play. Currently, GulfMark even trades at a slight price-to-book (0.96) discount to rivals SEACOR (1.04) and Tidewater (1.15), as well as energy-services giants like Baker Hughes (NYSE: BHI) (1.81), Halliburton (NYSE: HAL) (3.64), and Schlumberger (NYSE: SLB) (3.63).

Fellow Fool Jason Moser elaborates on the bargain opportunity:

This is the time to get in ... oil and natty gas supplies are high and people are sour on drilling in the Gulf at all. That will fade eventually and oil and natural gas will pop. [GulfMark] helps make it all happen and is trading well below historical tangible book levels. Solid management makes this one you can hang on to for a while.
