Relative Strength vs Relative Strength Index

09 Aug 2023

Understanding key market indicators is pivotal in the vast and ever-evolving world of financial trading. Let's discuss two such key concepts: Relative Strength (RS) and Relative Strength Index (RSI).

What is Relative Strength?

Often confused with Relative Strength Index, Relative Strength is a distinct concept in investment strategy. It is a momentum investing technique that compares the performance of an asset to that of the overall market. The formula is relatively straightforward:

  • Relative Strength = Price of a Security / Price of Market Index

When the Relative Strength increases, it suggests that the security is outperforming the market. Conversely, a decrease indicates underperformance. Traders and investors, like those at Motilal Oswal, use this metric to identify potential market leaders and laggards.

How is the Relative Strength Index Different?

On the other hand, the Relative Strength Index, or RSI, is a momentum oscillator that measures the speed and change of price movements. The RSI ranges between 0 and 100, providing insights into potentially overbought or oversold market conditions.

An RSI above 70 indicates that security might be overbought, suggesting a possible price reversal or pullback. On the flip side, an RSI below 30 indicates oversold conditions, implying a potential price increase in the near term.

How Can You Utilize RS and RSI in Trading?

The combination of the Relative Strength and Relative Strength Index offers valuable insights into trading. RS provides a comparative analysis between specific security and the market. 

Meanwhile, RSI offers a deeper dive into the security's own price momentum, indicating possible price reversals due to overbought or oversold conditions. Savvy traders harness these dual insights to make informed trading decisions.

For instance, let's say you're a customer with Motilal Oswal, using our seamless trading app, MO Investor. You observe security with high relative strength, indicating strong performance compared to the market. Furthermore, its RSI is below 30, suggesting it's currently oversold. These factors might indicate an ideal buying opportunity.

What Are the Benefits of Using RS and RSI?

Utilizing the Relative Strength and Relative Strength Index comes with numerous benefits:

  • It helps to identify market trends and potential reversal points.
  • Allow traders to assess the strength of security against the market and its own price momentum.
  • Guides in making informed trading decisions, reducing the risk of impulsive trades.


Remember, understanding the matrics is only one part of the bigger puzzle. The world of trading and investing is a marathon, not a sprint, and being armed with the right tools can make the journey significantly smoother.
