Technical Analysis

[RiverRider]

Im new to stock investing and I try to improve my knowledge in that area. I listen sometimes to a tv program where a guy who is supposely a technical analysis professionnal says he can predict the future evolution of a stock by ONLY looking at the stock graph of that company and by looking at the graph of others similar companies in the same area.

I must say that im sceptical about this method and I would like to know what you guys think about this.
