What Should Have Been Done Last Week What the Failure of Active Managers Proves

What Technical Analysis Focuses On

Technical analysis does not look at the management team, market, or any other subjective matter. Instead, this method of analysis tends to prefer looking at historical prices for stocks of specific companies and uses that data in conjunction with other variables of buying in order to make a decision. The end result is to be able to predict future patterns of prices on specific stocks. However, no proof has been provided illustrating any link between historical prices and how they perform in the future
