Definition
Technical analysis is the practice of forecasting price movement by studying a security's own trading history — its past prices, traded volume, and the geometric structure those prices form on a chart. It stands apart from fundamental analysis, which examines a company's earnings, balance sheet, and competitive position. The technical analyst assumes that everything knowable about an asset is already reflected in its price.
Its core premise is that price moves in trends and that patterns of crowd behavior tend to repeat. Because markets are driven by human emotion as much as by information, recurring formations on a chart are read as visible traces of fear, greed, and indecision among participants.
Why it matters
How it works
A technical analyst marks the levels where prior moves stalled, identifies the prevailing trend, and watches for chart patterns that suggest the trend will continue or reverse. Volume serves as a confirming witness: a breakout on heavy volume carries more weight than one on thin trading. Signals are typically acted on only after a defined confirmation event, and a predetermined level marks where the analyst's read is judged wrong.
The method is best understood as a structured way to interpret crowd behavior, not a crystal ball. It produces a disciplined process for sizing positions and limiting losses, which is often more valuable than any single prediction.
