Considering overall Risk Reward ratio of the strategy and smooth equity curve, Zero is a good stock trading strategy. So far I rate it as "Very Good" because I am not sure how it will perform in bear markets. For example, during Nov 08, it performed badly when Nasdaq dropped 372 points from high to low whereas in Feb 09, it performed well when Nasdaq dropped 200 points. So I need more evidence re. how the system is performing during those times as this is a long only system. If it passes that test, too, then it certainly deserves five star rating.
