Technical analysis is a method of evaluating securities by analyzing the statistics generated by market activity, such as past prices and volume. Technical analysts do not attempt to measure a security’s intrinsic value, but instead use charts and other tools to identify patterns that can suggest future activity.
Just as there are many investment styles on the fundamental side, there are also many different types of technical traders. Some rely on chart patterns, others use technical indicators and oscillators, and most use some combination of the two. In any case, technical analysts’ exclusive use of historical price and volume data is what separates them from their fundamental counterparts. Unlike fundamental analysts, technical analysts don’t care whether a stock is undervalued – the only thing that matters is a security’s past trading data and what information this data can provide about where the security might move in the future.
The field of technical analysis is based on three assumptions:
1. The market discounts everything.
2. Price moves in trends.
3. History tends to repeat itself.
