Just last month, one of those Fools, troym72, succinctly summed up the bull case for our community:

With a P/E just over 10 and incredible growth in their Natural Gas engine division, [Cummins] is well-positioned. Fleet vehicles with NG engines are on the road already with more coming. NG fueling stations are being built. Even if NG is a flop, Cummings is still a top-notch and well respected diesel engine builder.

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, Cummins may not be your top choice.
