The primary distinction between Relative Strength and the Relative Strength Index (RSI) is that Relative Strength compares the performance of one asset to another, while the RSI evaluates the momentum of price changes within a single asset.

What Is Relative Strength?
Relative Strength is a measure that compares the performance of one asset, such as a stock, against another, usually a benchmark index or another stock. It helps investors identify which asset is outperforming or underperforming in the market.
Relative Strength is often used by investors to gauge the strength of a particular asset relative to a benchmark. For example, if a stock’s price has increased by 10% while the benchmark index has risen by 5%, the stock is said to have a higher relative strength. This metric is crucial in helping investors make decisions on which assets to include in their portfolios based on their comparative performance.
For example, if you compare the performance of Stock A and Stock B over a period of time, and Stock A has increased by 15% while Stock B has only increased by 5%, Stock A is considered to have higher relative strength. This comparison helps investors identify which stock is performing better relative to others.
What Is Relative Strength Index?
The Relative Strength Index (RSI) is a technical tool that assesses the momentum of price changes in a particular asset. It measures the speed and extent of price shifts to identify whether an asset is overbought or oversold.
RSI values range from 0 to 100, helping traders evaluate a stock’s recent price momentum. A value above 70 typically signals that the asset may be overbought and could face a price correction. Conversely, a value below 30 suggests that the asset might be oversold and could be poised for a rebound.
For example, if a stock has been rising in price for several days and its RSI reaches 75, it may be considered overbought, signaling a potential price drop. Conversely, if the RSI falls to 25 after a series of declines, the stock might be oversold, indicating a possible price recovery.
Relative Strength Vs Relative Strength Index
The main difference between Relative Strength and Relative Strength Index is that Relative Strength compares the performance of one asset against another, while Relative Strength Index (RSI) measures the momentum and price movements of a single asset.
Other differences include:
- Purpose: Relative Strength is used to compare the performance of two assets, helping investors identify which asset is outperforming. RSI, on the other hand, is used to identify overbought or oversold conditions in one asset, indicating potential buy or sell signals.
- Calculation: Relative Strength is calculated by dividing the price of one asset by another, providing a straightforward comparison between the two. RSI is calculated using the average gains and losses over a specific period, typically 14 days, and helps quantify momentum.
- Application: Relative Strength helps in selecting assets for a portfolio by highlighting stronger performers. RSI aids in timing market entries and exits by signaling when an asset may be due for a reversal or continuation of its current trend.
- Time Frame: Relative Strength is generally observed over longer periods, making it useful for long-term investment strategies. RSI is often used for short-term trading decisions, as it provides quick insights into an asset’s recent price movements.
- Output: Relative Strength produces a ratio or percentage that shows how one asset is performing relative to another. RSI provides a value between 0 and 100, with values above 70 indicating overbought conditions and below 30 indicating oversold conditions.
| Parameter | Relative Strength | Relative Strength Index (RSI) |
| Purpose | Compare performance of two assets | Identify overbought or oversold conditions |
| Calculation | Price of one asset divided by another | Average gains and losses over a specific period |
| Application | Asset selection for portfolios | Market entry and exit timing |
| Time Frame | Observed over longer periods | Used for short-term trading decisions |
| Output | Ratio or percentage | Value between 0 and 100 |

Difference Between Relative Strength And Relative Strength Index – FAQs
The main difference between Relative Strength and Relative Strength Index is that Relative Strength compares the performance of one asset against another, while RSI measures the momentum of price movements within a single asset to identify overbought or oversold conditions.
The main difference between True Strength Index (TSI) and Relative Strength Index (RSI) is that TSI smooths out price data to reduce noise, providing a clearer trend signal, while RSI focuses on momentum to identify overbought or oversold conditions.
If RSI is above 50, it generally indicates that the asset is experiencing upward momentum, and the buying pressure is stronger than the selling pressure. It is often viewed as a signal that the asset may continue to rise.
The Relative Strength Index (RSI) is a tool used to spot potential buying or selling opportunities by evaluating the momentum of price changes. It assists traders in determining if an asset is overbought (above 70) or oversold (below 30).
The formula for Relative Strength is: Relative Strength = Average Gain / Average Loss. This calculation is used to determine the RSI, which then provides a momentum value on a scale of 0 to 100, indicating market conditions.
