Is the NYSI–NYAD divergence signaling distribution and imminent failed breakouts ahead?
IMGELD Market Breadth Update Based on Last 5 Days Till the Data: 2026-03-018
Executive Summary Date: 2026-03-19
Breadth weakened over the last five sessions. NYSI (McClellan Summation Index) fell steadily from 340.16 to 76.58, signaling persistent deterioration. NYAD (Advance–Decline Line) whipsawed, with two mid-period positive days overwhelmed by significant net declines, ending sharply negative on 2026-03-18. Volatility tone shifted from a brief compression to renewed expansion, with VIX (CBOE Volatility Index) rebounding to 25.09 and RVX (Russell Volatility Index) to 31.03.
Tactically, long opportunities are selective and should focus only on mid-cap industries showing improving leadership persistence, clean relative strength, and subdued new lows. Short opportunities remain valid in large caps where breadth is deteriorating and volatility is re-accelerating, especially in crowded, momentum-dependent industries. Selectivity is high.

Global Read
Participation is firmly narrowing across the window. Leadership shows signs of concentration rather than broad rotation, as NYHGH did not expand consistently and NYLOW re-accelerated into the latest session. Volatility shifted from three days of compression to renewed expansion, raising the risk of failed breakouts and gap risk. A clear divergence persists between a persistently declining NYSI and the two-day NYAD rebound, which failed to shift the underlying trend. The five-day pattern signals continuation of distribution, not early accumulation. By the five-day consistency rule: participation is firmly narrowing, leadership broadening remains tentative, and volatility expansion is tentatively resuming.
Indicator Breakdown
NYSI (McClellan Summation Index) Structure is firmly declining for five consecutive sessions, indicating erosion in intermediate breadth and rising risk of further downside until a base forms.
NYAD (Advance–Decline Line) Daily participation is mixed but net negative over five days. Two positive readings on 2026-03-16 and 2026-03-17 did not reverse the broader weakening, and the sharp negative close on 2026-03-18 suggests selling pressure regained control.
NYHGH (New 52-Week Highs) Highs were inconsistent, rising into 79 on 2026-03-17 then slipping to 64. This is not a broad leadership expansion, more consistent with narrow winners.
NYLOW (New 52-Week Lows) Lows compressed to 50 on 2026-03-17, then jumped to 117, indicating downside pressure resurged and risk appetite faded quickly.
Volatility Regime VIX eased from 27.29 to 22.37 before rebounding to 25.09. RVX followed the same path, ending at 31.03. The reversal higher signals a fragile tape where momentum is prone to reversals. Tactically, maintain an emphasis on risk control, avoid chasing strength, and prioritize mid-cap long ideas only where price and breadth are aligned. Large-cap shorts remain appropriate in overextended, breadth-thinning industries.
