On CAPS, 96.9% of the 870 members who have rated Clean Energy believe the stock will outperform the S&P 500 going forward. These bulls include MikeLCT and All-Star marc64, who is ranked in the top 3% of our community.

Less than two months ago, MikeLCT tapped the stock as one of two natural ways to gas up:

Natural Gas is in the cards for America. [Clean Energy] and [Westport Innovations] are top plays for NG Trucking and Bussing. These are the ['Apples'] of the near future.

In a pitch from last month, marc64 also pushed Fools to come clean:

Maybe I missed something but I think natural gas is going to be the cheapest, relatively clean energy source, around. It's going to be produced domestically in huge quantities, and in tough times those parts of the country with any are going to trip over themselves to cash in. ... The economics case for natural gas cars and trucks is going to be made pretty compellingly ... an expanded gas-dispensation infrastructure is going to make other gas fuels viable, like methane from industrial farm production. I think nirvana would be a natural gas/methane blend, plug-in hybrid.
