The Relative Strength Index and other tools can help investors identify oversold stocks based on stock price behavior. There’s no single definition of the term, so different analysts may come to different conclusions about whether a stock is oversold. To overcome some of the RSI’s limitations, traders often combine it with other technical analysis tools to generate more reliable signals and improve decision-making. Moving averages and candlestick patterns are two common tools used in conjunction with RSI.
