Interpretation guide
How to read U.S. market breadth
The U.S. Market Breadth radar shows what index levels alone cannot: whether participation is broad across U.S. equities. By comparing NYSE, Nasdaq, and AMEX breadth, 52-week high-low balance, and 20-day trend participation, the screen separates broad risk appetite from a rally led by only a handful of mega-cap stocks.
What it tracks
The screen measures breadth across U.S.-listed common stocks and depositary receipts above a market-cap threshold. Because it is based on individual-stock participation rather than index levels, it is useful for identifying narrow mega-cap-led markets.
- NYSE breadth reflects a broader mix of industrials, financials, cyclicals, and value stocks.
- Nasdaq breadth is more sensitive to technology and growth-stock risk appetite.
- AMEX has a smaller sample and is best treated as a secondary signal.
How to interpret it
When advancing share and Above 20D both improve, U.S. equity risk appetite is broadening. If Nasdaq indexes rise while breadth stays weak, the rally may be concentrated in mega-cap technology stocks.
- Advancing share above 55% shows healthy daily participation.
- Above 20D above 55% means short-term trend participation is broad.
- More 52-week lows than highs warns that medium-term internal strength is deteriorating.
How to respond
Strong U.S. breadth can support global risk appetite and spill over into Korean growth and semiconductor stocks. Weak breadth means investors should be careful about using headline Nasdaq strength as a broad bullish signal.
- If NYSE and Nasdaq breadth are both strong, the case for broader equity exposure improves.
- If only Nasdaq is strong, interpret the move as mega-cap or AI-led until breadth confirms.
- If breadth deteriorates quickly, cross-check VIX, the dollar, and interest-rate signals.
