Technical analysis looks at the demand and supply for securities based on trading volumes and price studies. Charting is a common method used to identify and project price trends in a security. A well-known technical indicator is the Bollinger Band. It creates two bands, one above and one below the price performance of a stock. The upper band is a resistance level and represents the level above which the stock is unlikely to rise. The bottom forms a support level and shows the price that a stock is unlikely to fall below.

According to technicians, if you see a significant “break” in the upper band, the expectation is that the stock price will fall in the immediate future. A “break” in the lower band signals that the security is about to rise in value. Either of these occurrences will dictate a unique investment strategy.
