Relative strength is a strategy used in momentum investing to identify value stocks. It involves selecting stocks or other investments that have performed well relative to the market as a whole or to a relevant benchmark. Technical analysts use an indicator known as the relative strength index (RSI) to generate overbought or oversold signals.
The relative strength line (RS) compares a stock's price performance to the S&P 500. When the line is sloping higher, the stock is outperforming the S&P 500; when it's moving sideways, it's in line with the S&P 500; and when it's sloping downward, it's underperforming.
Relative strength investing assumes that the current trend of outperformance will continue. If the trend reverses, the investment will likely underperform.
Relative strength has been shown to produce better risk-adjusted returns over time compared to other strategies. It is quantitative, objective, and provides easily definable entry and exit points for trades.

Relative strength is a strategy used in momentum investing to identify value stocks
To implement this strategy, investors start by selecting a benchmark such as the Nasdaq Composite Index or the S&P 500 index. They then identify companies within that market that have outperformed their peers by rising more rapidly or falling less rapidly. This approach assumes that the stocks that are outperforming the market will continue to do so.
Relative strength can be applied to individual stocks, whole markets, or industry sectors using index funds and exchange-traded funds (ETFs). It can also be used with other asset classes such as real estate investment trusts (REITs) and more exotic instruments like commodity futures and options.
One way to quantify relative strength is through the relative strength index (RSI), a technical indicator that measures the magnitude of recent price changes to evaluate overbought or oversold conditions. The RSI is displayed as an oscillator with a value between 0 and 100, where a reading above 70 indicates a stock may be overbought, and a reading below 30 suggests it may be oversold.
Another method for identifying relative strength is through pattern relative strength, which involves visually comparing the price action of two stocks or an index based on swing highs and lows. If one stock is setting higher lows while the other is setting lower lows, the former displays relative strength.
Relative strength is a valuable tool for investors as it helps identify stocks with the potential for significant gains while also reducing risk by focusing on those that tend to fall less sharply during market downturns. However, it is important to note that relative strength works best in stable periods and can be risky during chaotic periods or sudden trend reversals.

Relative strength investors assume that the trend of outperformance will continue
The goal of relative strength investing is to buy high and sell even higher. Relative strength investors assume that the trends displayed by the market will continue long enough for them to realise a positive return. Therefore, relative strength works best in stable periods with minimal disruption. Chaotic periods, such as the 2007-2008 financial crisis, can be dangerous for relative strength investors as they can lead to sharp reversals of investment trends.
Relative strength has been shown to be a strong investment factor, producing better risk-adjusted returns over time compared to other strategies. It is a quantitative, objective, and disciplined approach that provides easily definable entry and exit points for trades.
Research has shown that relative strength works particularly well with multiple asset classes, as the methodology can rotate towards less volatile asset classes during market turbulence. It has also been found to be effective with U.S. stocks, U.S. style boxes, U.S. sectors and industries, international stocks, bonds, commodities, and REITs.
Relative strength is best measured over an intermediate-term time frame, usually six to twelve months. It has been proven to be an effective risk-management tool and should be used by investors with a long time horizon and realistic expectations of its benefits.

Relative strength investing is most effective in stable periods with minimal disruption
Relative strength is a strategy used in momentum investing to identify stocks or other investments that have performed well relative to the market as a whole or to a relevant benchmark. It is based on the idea that present trends in the market will continue into the future. Therefore, relative strength investing is most effective in stable periods with minimal disruption.
Relative strength is often used to select investments that have been outperforming their market or benchmark, with the assumption that the trend of outperformance will continue. This strategy is effective in stable periods because it relies on the continuation of existing trends. If the market is relatively stable, with minimal disruptions or sharp reversals, the chances of the trend continuing are higher.
During chaotic periods, such as the 2007-2008 financial crisis, relative strength investing can be risky. In such situations, investor psychology can suddenly change, and previously popular investments may be shunned. Therefore, relative strength investing works best when markets are relatively calm and predictable.
Relative strength can be applied to various investment options, including individual stocks, whole markets, industry sectors, exchange-traded funds (ETFs), and other asset classes like real estate or commodities. It is a valuable tool for investors as it enables them to make well-informed decisions with confidence.
By using relative strength analysis, investors can identify emerging trends, capitalize on favourable market conditions, and make more informed investment choices. However, it is important to note that relative strength should not be the sole indicator for making investment decisions. Combining it with other technical and fundamental analysis tools can provide a more comprehensive view of the market.

The relative strength line compares a stock's price performance to the S&P 500
The relative strength line is a simple yet effective stock indicator. It compares a stock's price performance to the S&P 500, showing how a stock is performing compared to the general market. When shares outperform the S&P 500, the line trends higher, and when they lag, the line trends lower.
The relative strength line is calculated by dividing the price of the stock by the price of the S&P 500. The resulting ratio is then plotted on a chart. While the ratio value itself is not a useful metric, the trend of the line is highly valuable. With enough historical price data, investors can plot all the calculated ratios for a specified time period, usually daily or weekly, to visualise the relative strength line.
The relative strength line is a leading indicator, meaning it shows what the stock price is likely to do ahead of time. For example, an upward-trending relative strength line suggests the stock is outperforming the market, while a downward trend indicates underperformance.
The relative strength line is also great at identifying true leaders in the stock market. For instance, some stocks trading near new highs could be misleading if their relative strength lines are drooping. In this case, the relative strength line can be used to identify stocks that are truly outperforming the market.
Relative strength is a strategy used in momentum investing and in identifying value stocks. Relative strength investors select stocks that have been outperforming the market or a relevant benchmark, assuming that this trend of outperformance will continue.
Relative strength has been known as a valuable investment tool for a long time. For example, in Edwin Lefebvre's 1923 book, "Reminiscences of a Stock Operator," Jesse Livermore noted that " [p]rices are never too high to begin buying or too low to begin selling." This suggests that it is better to buy stocks showing high relative strength, as they are likely to continue increasing in price.
In summary, the relative strength line is a valuable tool for investors, helping them identify winning stocks and make more informed investment decisions.

The relative strength line is an invaluable tool for deciding when to sell stocks
The relative strength (RS) line is a valuable tool for investors to decide when to sell stocks. It compares a stock's price performance to a market benchmark, usually the S&P 500. When the RS line is sloping higher, the stock is outperforming the benchmark; when moving sideways, it is in line with the benchmark; and when sloping downward, it is underperforming.
The RS line is a useful indicator of a stock's health and can be used to identify stocks that are poised to head higher or lower. When a stock breaks out, the RS line should be rising sharply or ideally shooting into new high ground. If the RS line is already in new high ground ahead of the breakout, this is an even stronger signal.
For example, consider SolarWinds' failed breakouts in January and March 2013. In both cases, the RS line was lagging, indicating that the stock was not outperforming the market. As a result, the breakout attempts stalled, and the stock lost as much as 48% of its value in the following eight months.
In contrast, stocks with strong RS lines that snap back after weeks of being dormant can be potential leaders in the next market uptrend. For instance, Twilio's RS line surged to new highs in October 2020 after the company forecast strong sales growth. The stock then broke out and rose 21% in less than two weeks.
Another example is Alibaba, whose RS line hit new highs in July and August 2020 as the stock broke out of a flat base. The stock climbed 16% until it started its next base.
Therefore, the RS line is an invaluable tool for deciding when to sell stocks. It provides valuable insights into a stock's performance relative to the market and can help investors identify stocks that are poised to head higher or lower.

Frequently asked questions
Relative strength is a strategy used in momentum investing and in identifying value stocks. It involves selecting stocks or other investments that have performed well relative to the market as a whole or to a relevant benchmark.
There are several ways to calculate relative strength, but they all involve comparing a stock's performance to that of the overall market. One common method is to use the relative strength index (RSI), which is a technical indicator that measures the magnitude of recent price changes.
Relative strength has been shown to produce better risk-adjusted returns over time compared to other investment strategies. It is quantitative, objective, and provides clear entry and exit points for trades. It can also be applied to a wide range of asset classes, including stocks, bonds, commodities, and currencies.
Relative strength works best in stable periods with minimal disruption. In chaotic periods, such as financial crises, the trend of outperformance that relative strength investors rely on may reverse, leading to negative results. Additionally, relative strength tends to underperform at major market turning points as it is a trend-following strategy and requires time to adjust to new trends.
