A few months ago, one of those Fools, All-Star TMFBoomer, touched on the tailwinds working in the company's favor:

Clean Energy's bet on natural gas fueling station for fleets will payoff for long haul truckers just as it has for waste management companies and behind-the-fence operations. Even without government incentives, the price of upgrading existing tractor trailers has decreased substantially in recent years, and the fuel price discrepancy remains attractive as diesel prices have spiked. I do not think diesel will dip substantially even with an economic downturn because the cost of discovering/refining a barrel of oil has practically doubled in the past couple years. Companies seem more than willing to get into the natural gas game, and studies have shown that natural gas prices will not surge even with export plans in place.

If you want market-beating returns, you need to put together the best portfolio you can. Owning exceptional stocks is a surefire way to secure your financial future. Of course, despite a strong four-star rating, Clean Energy may not be your top choice.
