For example, if the RSI isn’t able to reach 70 on a number of consecutive price swings during an uptrend, but then drops below 30, the trend has weakened and could be reversing lower. To identify investment candidates, relative strength investors begin by observing a benchmark such as the Nasdaq Composite Index. They will then look to see which companies within that market have outperformed their peers, either by rising more rapidly than their peers or by falling less rapidly than them. A divergence occurs when a stock’s price moves one way and RSI moves in the opposite direction. Overbought refers to a stock that has increased rapidly in a short period of time and may reverse lower.

While the RSI can provide valuable insights, using it as a standalone indicator is generally not recommended.
