Relative Strength is a concept in technical analysis that compares the price movement of a security to a benchmark index or another security. This comparison helps traders identify whether a particular asset is outperforming or underperforming relative to its peers or the market overall. A common method to measure relative strength is the Relative Strength Index (RSI), which typically ranges from 0 to 100. An RSI above 70 may indicate that an asset is overbought, while an RSI below 30 may suggest it is oversold.
For example, if a stock is rising by 10% while the index is increasing only by 5%, one might conclude that the stock has strong relative strength. Conversely, if the stock is down 5% while the index is up 5%, the relative strength is weak. Understanding relative strength can help traders make informed decisions about timing their entries and exits, assessing market sentiment, and determining allocation among different assets.
