The Breadth Thrust Indicator: Definition, Application, and Market Implications
AN
Summary:
The Breadth Thrust Indicator is a significant technical tool used in the finance industry to gauge market momentum. Developed by Martin Zweig, it measures the ratio of advancing issues to total issues on an exchange, typically the New York Stock Exchange (NYSE), over a 10-day period. This indicator is particularly notable for its role in signaling potential new bull markets when it transitions from below 40% to above 61.5%. Understanding this indicator is crucial for market analysis and predicting trends.
What is the breadth thrust indicator?
The breadth thrust indicator is a technical tool utilized in the finance industry to assess market momentum. It calculates the ratio of advancing issues to total issues on an exchange, such as the New York Stock Exchange (NYSE), over a 10-day period. Developed by Martin Zweig, this indicator plays a significant role in identifying potential new bull markets when it surpasses certain threshold levels.
The basics of the breadth thrust indicator
Martin Zweig, an American stock investor and financial analyst, developed the breadth thrust indicator. According to Zweig, the concept is rooted in the principle that rapid changes in money flow within investment markets elevate stocks and indicate increased liquidity. The indicator focuses on the speed at which the advancing and declining numbers on the NYSE shift from negative to positive within a compressed timeframe.
The breadth thrust indicator is sometimes referred to as the Zweig Breadth Indicator, named after its creator. Zweig’s research indicates that there have been only 14 breadth thrusts since 1945. Following each of these occurrences, the market experienced an average gain of 24.6% over an average timeframe of 11 months. Zweig also notes that the majority of bull markets commence with a breadth thrust.
Interestingly, there were no breadth thrusts during the 25-year period from 1984 to 2009. However, this anomaly does not diminish the indicator’s analytical capabilities, as it was developed before this particular drought period and remains a widely watched metric in the financial community.
