Just Ask Icahn: Transocean Undervalued and Cruising

Tickers in this article: BP CAM GS NOV RIG

NEW YORK (TheStreet) -- It wasn't that long ago that offshore drilling giant Transocean was regarded as one of the better energy-related companies on the market, if not the best. Then the Macondo disaster occurred, which, alongside BP , cast Transocean for villain status after a rig explosion spilled 200 million gallons of crude oil into the Gulf of Mexico.

Transocean also has dealt with several operational issues that impacted efficiencies, not least of which involve unplanned downtime eating into the company's profits. Still, Transocean shares, now trading around $54 per share, have gained 26% year to date, though not because investors are surfing Transocean waves of excitement.

Although the stock looks healthy against rivals such as Cameron International and National Oilwell Varco , 24% of Transocean's rise has come in the past month. In fact, since the stock reached its 2013 high of $59.50 on Feb. 14, shares had fallen by as much as 26%, suggesting investors are still struggling with what to make of this company. If my suspicions are correct, things are about to change.

Namely, activist investor Carl Icahn (who currently owns roughly 5.6% of the company) is bullish. Icahn has an estimated stake approaching $1 billion. I'm not suggesting that Icahn's involvement suddenly makes Transocean a better investment, just that he has not lost many bets.

With better-than-expected results already in hand from National Oilwell Varco and Cameron, it wasn't an issue of whether Transocean would beat estimates, but by how much? Counting third-quarter revenue climbing more than 5% year over year to $2.56 billion, Transocean didn't disappoint. Not only did Transocean beat revenue estimates by $90 million, but the growth in the quarter more-than doubled the performance of National Oilwell Varco, a stock the Street loves to no end.

Goldman Sachs , on the other hand, was not impressed. While citing a variety of concerns, analyst Waqar Syed downgraded Transocean stock to "sell" and set a $50 price target, almost 10% below the current trading value. Among Syed's concerns has been the sudden increase in the stock, something he believes has climbed solely on the basis of the announcement that Transocean will be added to the S&P 500 index.
