Happy Halloween! So the kids in your neighborhood are putting together their Harry Potter costumes, but what about you? It's been a rough year all around, and you deserve a little fun this cavity-inducing holiday.

Well, how about some Trick or Treating, Fool-style? In lieu of candy, our writers are handing out their thoughts on stocks this Halloween. We've got a bowlful of Treats (stocks they like), Tricks (stocks they love to hate), and we've sprinkled in a few scary investing tales, too.

Remember, Fools: Investing can be a nightmare if you don't do your homework. These Tricks and Treats are not recommendations of any kind, but simply the opinions of Fool writers. Before even thinking about investing in one of these stocks, do your research and make your own decisions.
