If market price is below the intrinsic value, then the market is undervalued and should be bought. Both of these approaches to market forecasting attempt to solve the same problem, that is, to determine the direction prices are likely to move. They just approach the problem from different directions. Most market traders classify themselves as either technicians or fundamentalists. In reality, there is a lot of overlap.
Most fundamentalists have a working knowledge of the basic tenets of chart analysis.
At the same time, most technicians have at least a passing awareness of the fundamentals. The problem is that the charts and fundamentals are often in conflict with each other. Usually at the beginning of important market moves, the fundamentals do not explain or support what the market seems to be doing. It is at these critical times in the trend that these two approaches seem to differ the most. Usually they come back into sync at some point, but often too late for the trader to act.
