I guess in the market, the two camps of TA (technical analysis) and FA (fundamental analysis) works the same too. They are different; they see different things and do different things. You can even say they are opposite, but I think they are complementary to each other. One just have to look at how successful AK applies his knowledge of both to his positions to know that it can be done. I guess each camp can learn a little from the other, if you keep your mind open and receptive to new ideas. It's really like two blind men trying to figure out how an elephant feels like by touching different parts of it - you are really only seeing one perspective of the bigger picture.
I think I did a post on this topic before. It's found here. Must be getting old and naggy.
