Market Breadth Breakdown: Why the Market Has “Bad Breadth” in March 2026

David Keller
by David Keller,
President and Chief Strategist, Sierra Alpha Research

Dave explains why market breadth conditions have deteriorated even while the S&P 500 and Nasdaq have remained relatively flat in early 2026. Using indicators like cumulative advance-decline lines, moving-average breadth, and bullish percent indexes, he shows how fewer stocks are participating in the market’s trend and why participation matters for the sustainability of a rally. Dave also compares equal-weighted versus cap-weighted performance and highlights key technical levels and momentum signals that could confirm whether weakening breadth leads to broader market downside.
