Experienced trader in the equity markets. However, I take a different viewpoint. I trade people rather then stocks. I firmly believe that to be a successful trader it is far more important to understand human psychology then to understand finance. By taking smart contrarian positions - while giving respect to the idea that the market can be wrong longer then you can stay solvent - we try to pinpoint the areas where either of the two market emotions (fear and greed) have decoupled the price from the reality. If we understand these, we can exploit huge inefficiencies in the market.
Should be noted I am NOT a trading professional. My background is in behavioral sciences, not finance, and this allows me to "think outside the box" and avoid the groupthink that permeates ANY homogenous group, no matter how smart or well intentioned they may be. Always good to have a fresh set of eyes attacking a problem.
