Relative Strength - What Is It, Explained, Example, Calculation (2024)

What Is Relative Strength?

Relative strength is a financial analysis tool used to compare the performance of securities or assets to a benchmark index. Its analysis aims to identify securities or assets that outperform or underperform the benchmark index.

Relative strength analysis has significant importance in the financial industry. It provides investors with a tool to identify securities or assets that are performing well and have the potential for future growth. Identifying outperforming or underperforming securities or assets helps investors make informed investment decisions and potentially earn higher returns.

• Relative strength is a tool used in technical analysis to compare the price performance of one stock or asset to a benchmark, such as an index, over a given period.
• It measures the price of a security relative to a benchmark and helps identify which security is performing better or worse than the benchmark.
• The analysis based on this technique can be used to identify trends and potential investment opportunities in the financial markets. It can be a useful tool in making buy/sell decisions.

Relative Strength Explained

Relative strength is the measurement of the price trend of one security or asset relative to another, providing insight into the security's performance compared to its benchmark. Relative strength analysis is commonly used in various investment strategies, including momentum investing, which involves buying securities that have shown strong relative strength over a certain period. Additionally, the analysis can diversify an investment portfolio by selecting securities from different industries or sectors that outperform their benchmarks.

The process behind relative strength analysis involves several steps:

• First, identify the securities or assets to compare:The first step is to choose the securities or assets to compare. For example, a tradermay want to compare the performance of a particular stock with the performance of the overall stock market.
• Calculate the relative strength ratio:The next step is to calculate the ratio by dividing one asset's price by another's price. For example, divide the price of the stock they are analyzing by the price of a market index, such as the S&P 500. The resulting ratio represents the performance of the stock relative to the benchmark.
• Chart the ratio:Traders can chart it over time after calculating it. This allows them to see how the performance of the stock or asset they are analyzing compares to the benchmark over time.
• Analyze the trend:By analyzing the trend of the relative strength ratio, a trader can determine whether the stock or asset is outperforming or underperforming the benchmark. If the ratio is trending upward, it indicates that the stock is outperforming the benchmark, while a downward trend suggests the opposite.
• Use the information to make investment decisions:Finally, the trader can use the information from the analysis to make informed investment decisions. For example, if a stock shows strong relative strength, a day trader may consider buying it as a potential investment opportunity.

How To Calculate?

The relative strength of a security or investment can be calculated using the following formula:

Relative strength = (Price of Security A / Price of Security B) x 100

In this formula, security A is the security a trader analyzes, and security B is the benchmark or reference security they compare it to. For example, a trader may compare the price of a particular stock with the price of a market index, such as the S&P 500.

To calculate the relative strength using this formula, divide the price of security A by the price of security B and then multiply the result by 100. The resulting number represents the relative strength of security A compared to security B.

After calculating it, the trader can plot it on a chart to analyze its trend. By comparing the relative strength of different securities, investors can identify which ones outperform or underperform their benchmarks and make informed investment decisions.

Examples

Let us look at some examples to understand the concept better:

Example #1

Let's say Alice wants to compare the performance of stock ABC with the performance of the S&P 500 index over six months. Here are the closing prices for each at the end of each month:

Month 1: ABC = $50, S&P 500 = $4,000

Month 2: ABC = $55, S&P 500 = $4,100

Month 3: ABC = $57, S&P 500 = $4,200

Month 4: ABC = $60, S&P 500 = $4,300

Month 5: ABC = $58, S&P 500 = $4,400

Month 6: ABC = $62, S&P 500 = $4,500

To calculate the relative strength of ABC compared to the S&P 500, we use the formula:

(Price of ABC / Price of S&P 500) x 100

So for each month, Alice can calculate the relative strength as follows:

Month 1: (50 / 4,000) x 100 = 1.25

Month 2: (55 / 4,100) x 100 = 1.34

Month 3: (57 / 4,200) x 100 = 1.36

Month 4: (60 / 4,300) x 100 = 1.40

Month 5: (58 / 4,400) x 100 = 1.32

Month 6: (62 / 4,500) x 100 = 1.38

Alice can then plot the relative strength of ABC on a chart over the six months to see its trend, and Alice can see that the calculated value of ABC compared to the S&P 500 has generally been increasing over the six months. This indicates that ABC has been outperforming the S&P 500 over this time. An investor can use this information to make informed investment decisions, such as potentially buying ABC as a potential investment opportunity.

Example #2

A great example from during the COVID bear market is B&G Foods (BGS), the name behind Crisco, Cream of Wheat, and Green Giant, among other major food brands. So while the rest of the market (including B&G's consumer staples sector!) was getting hammered, B&G wasn't merely relatively strong—it was outright strong.

B&G Foods (BGS) stood out as a company with strong relative strength, which, combined with its juicy dividend, made it an attractive investment option. However, BGS's debt and market capitalization caught up to it amid rising interest rates and inflationary pressures, leading to a60% dividend cut in 2022.

Relative Strength vs Relative Strength Index

Technically, both are useful technical indicators for traders and investors to evaluate the performance of securities over a specified time frame. However, while relative strength measures a security's strength relative to its past performance, the relative strength index measures the magnitude and speed of price movements. As a result, it can help identify overbought or oversold conditions.
