Technical Analysis does have its critics – those economists who say it is nothing more than a pseudoscience, one that has no basis in fact. Investors such as Warren Buffett and Peter Lynch say that there is precious little evidence that Technical Analysis works. However, various academic studies have shown that technical analysis, particularly when carried out by neural networks, can produce statistically significant returns, and many investors have made fortunes through the application of its principles. It is therefore unfair to dismiss it as mere nonsense, and one ignores it at one’s peril!
