By technical analysis (TA), I mean those candle charts, wave theory etc. Those are techniques day traders use frequently to make small profit out of price fluctuation. Nothing against it, but I feel those techniques are not useful for long term investors. Actually from I read, Buffett also learned all those stuff before, but obviously he did not make his fortune from TA.
The interesting point is, Ba Shu Song (巴曙松), the rising Chinese economist, seems also believed in this. From his blog post 投資港股有用網站連結, he listed some TA web sites in the end.
