Fundamental analysis is very helpful but I agree with you that it is sometimes misleading that will guide your funds to losses. That is why technical analysis is here to support those decisions in trading. When I am doing my research with trading, it is always advisable to combine TA and FA which will give you better view what is going on with the market. What I usually do is trading only 10% to 15% of my funds and the rest will act as a support for buy backs.
