Just last week, one of those bulls, rdub76, touched on the tailwinds working in Westport's favor:

The exponential increase in recoverable natural gas combined with the ever increasing eco awareness will drive the desire for vehicles to run natural gas. Electric vehicles just aren't viable for most people and the technology isn't developing fast enough to change that. The geopolitical disaster that is the [Middle East] is driving people and politicians to decrease and eventually eliminate our dependence on foreign oil and [Westport's] technology is one way to begin to solve all of these problems.

If you want market-topping 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 its five-star rating, Westport may not be your top choice.
