Technical analysis is like a thermometer. Fundamentalists who say they are not going to pay any attention to the charts are like a doctor who says he’s not going to take a patient’s temperature. But, of course, that would be sheer folly. If you are a responsible participant in the market, you always want to know where the market is — whether it is hot and excitable, or cold and stagnant. You want to know everything you can about the market to give you an edge.
