Market Breadth and Divergence

A security analysis indicator that shows how well stocks are moving in a trend is known as market breadth. Market breadth is the ratio of advancing stocks to declining ones. Divergence is the opposite of market breadth. If there is a large increase in the number of advancing stocks, market breadth is generally considered to be positive. Traders use market breadth to evaluate the trend of a stock. Moreover, it may indicate a good time to buy or sell a stock.

Positive market breadth

If you’re interested in the health of a stock market, a key indicator is positive market breadth. Positive market breadth indicates a broad bullish sentiment among equities. In a bear market, on the other hand, the majority of stocks decline. When this happens, the index is likely to decline. A healthy bull market is defined by the majority of stocks rising with the overall index. If your index has negative market breadth, you might want to sell your stocks now.

A positive market breadth indicator shows that a stock is moving up in volume. A stock with a rising index indicates positive market momentum. In contrast, a stock with a falling index shows negative market momentum. While these indicators may not be used to make a trading decision, they can help investors and traders determine what kind of trades to make. When positive market breadth indicates a stock is going higher and a bearish index shows a weaker trend, you should buy.

The term “market breadth” refers to the number of stocks participating in a trend. When market breadth is negative, this indicates a bearish trend, where the trend is being driven by a small number of stocks with large gains. In contrast, a positive market breadth indicates that bulls are in control of the momentum and price moves. However, when it’s negative, there’s a strong disproportionate number of stocks falling and a small percentage of stocks advancing.


The AT50 (Average True Range) is a popular technical indicator for gauging stock market breadth. This indicator relates the daily price action of stocks to the market’s breadth. As a rule of thumb, divergence in market breadth usually precedes a major market correction. Divergences are often accompanied by short-term pullbacks, and the longer they persist, the more severe the market correction will be. The AT50 can also be used to predict market direction, and this is one way of measuring it.

Indicators like the Advance/Decline line are essential for understanding the internal strength of a market. Their positive reading indicates bullish momentum and negative readings indicate bearish momentum. However, there are certain limitations to using these indicators. First of all, they lack the fine-tuning aspect of trend detection. Additionally, they only work well on weekly charts. And finally, diversification does not imply that a market will remain irrational for long.

The opposite is also true. The Dow has tended to trail the broader market. However, the Transportation Average, which is often a leading indicator, is often a good guide for determining the health of the U.S. economy. However, the transports (which track smaller companies) are not exhibiting any negative divergence, although they are lagging behind the broader market. The broader market is currently showing signs of a bull market, but this doesn’t mean that the broader markets are in danger of crashing.

Advance-decline line

The Advance-Decline line of market breadth is a popular technical indicator that helps traders to determine trends. It works by measuring the difference between advancing and declining issues over a given time period. The difference is then added to the cumulative advance-decline total of advancing and declining issues on the NYSE. As market breadth trends change, the Advance-Decline line rises and falls along with the overall trend. Here’s an example chart of the Advance-Decline line:

While analyzing the advance-decline line, keep in mind that there are other metrics that you should consider. While the market indexes are important indicators, the Advance-Decline line gives you an idea of individual stock performance. For example, if an index increases, but then decreases the next day, the Advance-Decline line tells you that it’s a false trend.

Another popular technical indicator is the Advance-Decline (A/D) line. It provides traders with two signals: the strength of a trend and the size of participation among stocks. Using the A/D line, traders can confirm trend strength and avoid buying at the top, which is one of the most common mistakes. A rising advance-decline line means that a trend is in place and prices will continue to move higher. Conversely, a declining advance-decline line indicates a slowing trend.
