It is important to keep in mind that price can ride the upper or lower band for longer than you might expect prior to reverting to the mean. Therefore, Bollinger Bands shouldn’t be used alone as a "buy" or "sell" signal but as a confirmation tool for other indicators.

If you discover this is the case, dig a little deeper into the fundamentals and news about the company. If what you find confirms that price has moved too far in either direction, it may be a sign to add to the position or to start to take profits.
