On CAPS, 89% of the 387 members who have rated Rentech believe the stock will outperform the S&P 500 going forward. These bulls include mspracticality and khomeboy.

Earlier this month, mspracticality tapped the stock as a potent way to go green: "US Air Force has already approved Rentech's jet fuel and several airlines in Los Angeles and Houston have committed to using their bio-diesel when it becomes available. A potential takeover candidate but future looks bright as a stand alone."

Over the past three quarters, in fact, Rentech has posted solid average revenue growth of 37.2%. Naturally, that's much faster than larger listed rivals like BP (11.8%), Exxon (19.5), and Sasol (16.3%).

CAPS member khomeboy elaborates on the Rentech bull case:

Middle East turmoil make alt fuels attractive. Also, if larger oil companies see opportunity, they may make a run at small independents ... military is also looking at alt fuel should supplies be limited and of course there is the Green movement that could support some upward pricing. I am buying and holding.
