A couple of months ago , one of those bulls, MidwestThales, succinctly summed up the bull case for our community:

Westport appears to be an innovator and a successful collaborator. Investing in [natural gas] is bound to be a turbulent ride, especially if petrol prices continue stable or fall. But I look at [natural gas] as I look at solar and wind: it's only a matter of time before we wise up and switch to sustainable sources of energy, and I'll be glad to have entered on the ground floor. As an investor, I have the time.

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 a strong five-star rating, Westport may not be your top choice.
