The Role of Market Breadth in Trend Analysis
Market breadth is a useful lens for understanding participation, equal-weight indexes and trend confirmation. Breadth measures how widely a move is shared across stocks, sectors or markets. Narrow leadership can persist, but broad participation often provides stronger confirmation of a durable trend.
Why it matters for portfolios
Breadth is a confirmation tool, not a timing signal; it works best alongside price, earnings and liquidity analysis.
What to watch
advance-decline lines, equal-weight relative performance, new highs and sector participation
