On CAPS, 99% of the 364 members who have rated Westport so far believe the stock will outperform the S&P 500 going forward. These bulls include craigt111 and All-Star TMFthump, who is ranked in the top 5% of our community.

Earlier this month , craigt111 touched on the tailwinds working in Westport's favor:

The intn'l natural gas market -- already ahead of the United States in implementation -- will sustain this company's stock, regardless of America's commitment. Recently, UPS (NYSE: UPS) made a large commitment to public-access LNG stations, plus 1,100 fleet trucks powered by Westport.

Over the next five years, in fact, Westport is expected to grow its bottom line at a brisk rate of 30% annually. That's faster than other clean energy plays like Fuel Systems Solutions (Nasdaq: FSYS) (15%) and Tesla Motors (Nasdaq: TSLA) (20%).

CAPS All-Star TMFthump expands on Westport as an overlooked opportunity:

I've been building positions in natural gas believing that it's only a matter of time until we choose some tangible way of distancing ourselves from war and turmoil in the Middle East. My oversight was that the stocks I've been adding are exclusively focus on the exploration and delivery side of this natural resource. With [Westport] I'm acknowledging that mistake and trying to look at opportunities beyond just energy companies.
