Relative Strength Indicator (RSI) -    87+

 

The Relative Strength Indicator (RSI) provides a measure of the strength of a stock’s recent price movements relative to a comparative market index. For U.S. markets (NYSE, NASDAQ, AMEX), U.S. indexes, and international indexes, the comparative index is the S&P 500 Index. For the Toronto Stock Exchange, the comparative index is the S&P/TSX Composite Index.

The RSI is made up of two parts, a numerical value followed by a ‘+’ or ‘–‘ sign.

The numerical value is indexed to a base of 100 for easy comparisons, and is calculated by comparing a stock’s price movement relative to the comparative market index over a period of 13 weeks. Stocks with an RSI above 100 are outperforming the comparative market index over the 13-week period, while those with an RSI below 100 are under-performing the index during that period.

For example, a stock with an RSI value of 115 has outperformed the market by 15% over the past 13 weeks, while a stock with a value of 85 has under-performed by 15%.

The RSI value is a momentum indicator – it will often oscillate over time as the stock price advances, stalls, or falters. Generally, stocks with a rising RSI value can anticipate even further price advances.

The second part of the RSI is based on a stock’s price movement relative to the comparative market index in the most current week. A stock that has out-performed the market index for the week would be tagged with a ‘+’, while any stock that under-performed the market index would be tagged with a ‘–‘.

For example, if a stock has advanced 8% on the week, while the market advanced only 3%, the stock would have a ‘+’ beside the RSI value. If a stock advanced only 2% and the market advanced 3%, it would display a ‘–‘ beside its RSI value. Alternatively, if a stock declined 3% on the week, while the market declined 5%, the stock would qualify for a ‘+’ beside the RSI value, denoting its relatively superior performance. However, if the stock had declined more than 5%, it would show a ‘–‘.

As a further example of both parts of the RSI, given a stock with an RSI of 87+, the value 87 indicates that the stock has under-performed the comparative market index by 13% over a 13-week period, but has outperformed the same comparative market index during the most recent week.

The (+/-) relative strength indicator is extremely useful in both advancing and declining markets, as it isolates stocks that are not moving with the prevailing market trend.

    From Banks to Bytes to Uranium: Strong Bulls Align with ST-IM Signals On September 17, 2025, the U.S. Federal Reserve delivered its first interest rate cut in nine months, lowering the federal funds rate by 25 basis points to a new target range of 4.00%–4.25%.

    Money management and trading psychology: building a resilient trading plan that integrates with the Stock Trends decision-tree framework Financial markets are unpredictable. Even when a trading strategy has a positive expectancy, a few bad trades can wipe out an account if position sizes are too large or emotions override discipline. Academic studies show that how much capital is allocated per trade is more influential on long‑term returns than the specific trading system used. For example, research cited by position‑sizing specialist Van Tharp found that…
