Call me a conspiracy theorist but I believe that the debate over this is a good thing. I firmly believe that the market must consist of largely fundamentalists in order to facilitate technicians existence. After all, how could all things be discounted by the market if everyone was a technician?
All it takes is to read something like Market Wizards and you'll see that both work very well. Its mastering something you do poorly that makes the difference. If one side of the fence was wrong then half of the people in that book would not have been able to do what they did.
I guess if you think about property, some like to buy and rent out, some like to develop and sell on, some like to renovate. Master any discipline and you're ahead.
