On CAPS, 98% of the 1,306 members who have rated Westport believe the stock will outperform the S&P 500 going forward.

A few weeks ago, one of those Fools, asprice81, succinctly summed up the bull case for our community:

With the price of natural gas continuing to go lower and the price of oil staying above $100 I see the shift toward natural gas powered vehicles becoming a reality. Westport has made strategic business alliances with some of the top players in business, such as Cummins and Caterpillar. America will use its own resources to break its reliance on OPEC. ... [Current price] will seem like a gift when you look at the price of this in 2013.

If you want to retire rich, 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 five-star rating, Westport may not be your top choice.
