In the ever-evolving world of financial markets, staying ahead of the curve is crucial for investors. One of the most effective tools for achieving this is the Relative Strength Index (RSI), a momentum oscillator that measures the speed and change of price movements. This article delves into the RSI analysis of US large cap momentum stocks as of September 2025, providing valuable insights for investors looking to capitalize on market trends.
Understanding RSI and Its Importance
The RSI is a widely used technical analysis tool that ranges from 0 to 100. It measures the magnitude of recent price changes to evaluate overbought or oversold conditions in a stock. Typically, an RSI above 70 indicates an overbought condition, suggesting that a stock may be due for a pullback, while an RSI below 30 indicates an oversold condition, indicating a potential buying opportunity.
