Interpreting Market Health

The Complete Picture

Individual indicators tell stories. Combined, they reveal truth. Market health isn’t binary—it’s a spectrum measured across multiple dimensions simultaneously.

Professional traders synthesize breadth, momentum, sentiment, and structure into composite health scores. This article shows you how to build that intuition.

The Health Check Framework

Trend Health

– Price action: Higher highs and higher lows (bullish)
– Moving averages: Price above key MAs, MAs sloping up
– Breadth: A/D Line confirming price direction

Momentum Health

– RSI: Not extreme, room to run
– MACD: Histogram expanding in trend direction
– New highs vs lows: Expanding in bull markets

Participation Health

– % stocks above 50-day MA: 50-70% ideal
– Sector correlation: Most sectors participating
– Volume: Increasing on rallies, decreasing on declines
