The tensionConditions like today historically favored a 0.38% average move over the forward five sessions, but the worst outcome was -4.86%.

Historical conditions were mixed across 139 matches: a 0.38% average forward move against a -4.86% worst outcome.
Defensive posture: breadth damage and Market Health outweigh the constructive historical average.
05 Tomorrow's tripwires
Three checks that settle the argument
CONFIRM
A/D 86/410, Bear Market phase, and Very High risk keep the defensive read intact.
WATCH
Historical outcomes remain uneven: 0.38% average forward move and -4.86% worst outcome across 139 matches.
BREAK
The defensive thesis breaks if the Weakening trend and 17-session Bear Market run no longer describe conditions.
The ledger
Where that leaves us
Lines up bullish
139 historical matches averaged a 0.38% forward move.
Turnover at 0.84× the 20-day average was not elevated.
Lines up bearish
A/D was 86/410.
Market Health Index (MHI) was 9.71 at the 1.0 percentile.
The phase was Bear Market with Very High risk.
Net read: Net view: defensive, with a positive historical average offset by Very High risk and a Weakening Bear Market.
A 1.1% decline matters less than A/D 86/410. Conditions like today historically favored a 0.38% average forward move, but Market Health Index (MHI) at 9.71 keeps the setup defensive.
