The 9 Indicators to Measure Market Breadth | Global Financial Markets

By analyzing market breadth, we can gain valuable insights into the health and direction of the global financial markets. This article delves into various market breadth tools and their application in emerging equity indices.

Market Breadth: Unveiling the Underlying Strength

Market breadth goes beyond just price movements of an index. It analyzes how many stocks are participating in the move, offering a more nuanced picture. Here's an arsenal of tools to dissect market breadth:

• Advance-Decline (AD) Line: Tracks the difference between advancing and declining issues on a daily basis. A rising AD line suggests bullish sentiment, and vice versa.

• Advance-Decline Index (ADI): A smoothed version of the AD Line, offering a clearer trend. Values above zero indicate a broad market advance, while values below zero suggest weakness.

• McClellan Oscillator: Measures the difference between the number of new highs and new lows. Positive values suggest bullishness, while negative values signal bearishness.

• McClellan Summation Index: A cumulative version of the McClellan Oscillator, highlighting the market's overall direction. Rising values suggest accumulation, while falling values indicate distribution.

• Plurality Index: Indicates whether more stocks are advancing, declining, or unchanged. A positive reading suggests a bullish bias, while a negative reading leans bearish.

• Absolute Breadth Index (ABI): Similar to the Plurality Index but incorporates the magnitude of price changes. A positive ABI suggests a strong advance, while a negative ABI indicates a strong decline.

• Unchanged Issues: Tracks the number of stocks that remain unchanged on a given day. A high number of unchanged issues can signal indecision or a potential turning point.

• Advance-Decline Ratio (A/D Ratio): The ratio of advancing issues to declining issues. A value above 1 suggests a broad market advance, while a value below 1 indicates weakness.

• New Highs-New Lows (New H-L): Compares the number of new 52-week highs to new 52-week lows. A rising New H-L ratio suggests a healthy market, while a declining ratio indicates potential weakness.

Trading Signals: Putting Theory into Practice

These tools can generate valuable trading signals:

• Buy Signal: A sustained rise in the AD Line, ADI above zero, positive McClellan Oscillator/Summation Index, positive Plurality/ABI, rising A/D Ratio, and increasing New H-L ratio all suggest potential buying opportunities.

• Sell Signal: A declining AD Line, ADI below zero, negative McClellan Oscillator/Summation Index, negative Plurality/ABI, falling A/D Ratio, and decreasing New H-L ratio might indicate a time to sell or be cautious.

Emerging Equity Indices: A Tailored Approach

While these tools are valuable for established markets, some adjustments are necessary for emerging markets:

• Focus on Leading Indices: Analyze the leading index of the specific emerging market for a broader picture.

• Liquidity Considerations: Emerging markets might have lower trading volumes. Consider using percentage changes instead of raw numbers for AD calculations.

• Volatility Adjustments: Emerging markets can be more volatile. Consider using volatility filters to avoid false signals.

Remember: Market breadth analysis is a powerful tool, but it should be used in conjunction with other technical and fundamental analysis techniques for a more comprehensive understanding of the markets.
