A person who engages in technical analysis, especially professionally. Technical analysts use statistics to determine trends in security prices, and make or recommend investment decisions based on those trends. They do not attempt to determine the intrinsic value of securities, but instead focus on matters such as trade volume, demand, and volatility. Technical analysts often evaluate short-term trends almost exclusively, which is both a strength and a weakness in their analysis. They are sometimes called chartists because of the importance charts have in technical analysis. See also: Fundamental analysis.
