Where that leaves us

Lines up bullish
  • Net gamma +44,655 versus -44,233 prior.
  • Regime flipped from Acceleration Risk to Stabilizing.
  • Conditions like today historically favored a 0.3% average five-day outcome.
Lines up bearish
  • Bear Market phase with Weakening trend.
  • Very High risk with Market Health Index (MHI) 16.77.
  • Five-day analog worst case: -5.31%.

Net read: Stabilizing dealer conditions do not erase a Bear Market, Weakening trend and Very High-risk backdrop.

The turn is real, but the backdrop is not repaired: dealers moved to Stabilizing while Market Health Index (MHI) remained 16.77 in Bear Market.
