Over on CAPS, fully 669 of the 694 members who have rated Clean Energy -- some 96% -- believe the stock will outperform the S&P 500 going forward. These Foolish bulls include OSTATEBOY and Itpage.

Just last week, CAPS All-Star OSTATEBOY kept the bullish case simple: "T.Boone pickens company. Don't really need to say much more than that. This company is destined for greatness and is trading well below what it will be in the next few years. Big growth here."

An earlier pitch from Itpage shares that sentiment, noting that although Nancy Pelosi's stake in Clean Energy is nice, the stock has plenty more tailwinds working in its favor:

Regardless of the Speaker of the House's position in CLNE, America needs the infrastructure to capitalize on cheaper, cleaner fuel for the nations public transportation. This should bode well for CLNE's growth over the next several years. Compressed Natural Gas is the way to go.
