What is a Relative Strength Index? (RSI)

Relative Strength Index (RSI): Represented as a number between 0 and 100, RSI analyzes whether a security's price movement is a product of it being overbought or oversold. RSI can also be used to see which assets are primed for a trend reversal or correction in price. A security is generally considered oversold when the RSI is below 30, and overbought when the RSI is above 70.
