FYI: Stan Lee, legendary creator of countless Marvel comic book superheroes, didn't follow the crowd. He was unconventional. Unlike other comic book heroes, Lee's protagonists--Spiderman, Iron Man, and the Incredible Hulk, among them--had flaws. Lee's heroes overcame their flaws to do great things.
When it comes to investing, few of us are like Stan Lee. It's tough to go against the crowd when your money's on the line. Herding--or following said crowd--is much easier to do. Buying what others aren't, or when others aren't, takes a special constitution: the constitution of a contrarian.
