The split between the camps of technical and fundamental analysis is quite clear.
Fundamental analysts believe they are right, while technicians believe the market is right.
To wit, fundamentalists prepare their analysis and forecasts and check the market to see if the market's valuation differs from theirs. If it does they sell if the market's valuation is higher and buy if it is lower. Technicians, like fundamentalists, prepare their analysis and forecasts. The material is different, market data versus company data, but the process is similar. Then technicians check the market to see what it is doing and if it is agreement with their outlook they act, if not they wait for a better opportunity.
