Market Breadth Indicators: What They’re Saying Now
Introduction
When markets rise or fall, it’s easy to focus on index levels alone—but smart traders dig deeper. Market breadth indicators help gauge the strength behind a market move. In this blog, we analyze key breadth signals and what they reveal about the current state of the U.S. equity market.
1. What Are Market Breadth Indicators?
Market breadth indicators measure how many individual stocks participate in a market move. They help determine whether a rally or decline is broad-based or driven by just a few large-cap names.
Key benefits of breadth analysis:
- Confirms or contradicts index movements
- Detects underlying weakness before corrections
- Helps validate bullish or bearish momentum
2. Advance/Decline (A/D) Line
The A/D Line tracks the difference between the number of advancing and declining stocks. A rising A/D line alongside rising indices signals strong market participation.
Current Status:
The A/D line is climbing steadily, suggesting broad market support behind the S&P 500’s latest rally.
3. Percentage of Stocks Above 50-Day Moving Average
This indicator tells how many stocks are in short-term uptrends. When this percentage rises, market health improves.
- Bullish above 70%
- Neutral between 50-70%
- Bearish below 40%
Current Status:
At 64%, this metric shows moderate bullish sentiment with room for further upside.
4. McClellan Oscillator
This momentum oscillator evaluates short-term breadth momentum using exponential moving averages of advances and declines.
- Positive readings = bullish momentum
- Negative readings = bearish momentum
Current Status:
The McClellan Oscillator is slightly positive, indicating steady but cautious momentum.
5. Cumulative Volume Index (CVI)
The CVI adds up volume from advancing and subtracts volume from declining stocks. It helps track “real money” flow.
Current Status:
The CVI is trending upward—suggesting institutional accumulation beneath the surface.
6. Divergences to Watch
Sometimes indices move higher while breadth weakens. This negative divergence can signal an upcoming correction.
Watch for:
- New highs in S&P 500 without confirmation from A/D line
- Lower percentage of stocks above 50-DMA despite price gains
Conclusion
Market breadth indicators offer a powerful lens for evaluating the quality of a rally or decline. Right now, most metrics support the bullish trend—but traders should stay alert for divergence signs as markets test resistance zones.
