Risk got trimmed into tomorrow's CPI, with the S&P and Nasdaq fading from last week's record close on an oil-driven, pre-data de-risking.
The tape sold off gradually through the day rather than gapping down, consistent with positioning trims ahead of Wednesday's 8:30am CPI print, which consensus sees at +0.1% month-over-month after June's surprise decline. Iran's refusal to reopen the Strait of Hormuz without compensation kept crude above $83 and put a bid under energy while banks lost their earlier yield-relief bounce. Alphabet's slide did the real damage to the Nasdaq, spilling into the optical/AI-infra complex that had run hot on prior transceiver headlines; Datadog was the lone bright spot on clean earnings follow-through. Small caps and industrials held up best, a classic pre-CPI rotation out of crowded mega-cap tech into laggards.
The S&P closed down about three tenths, Dow similarly soft, Nasdaq underperforming near six tenths lower — a controlled pullback that left the index still within shouting distance of Friday's all-time high rather than a trend break. VIX ticked up off its lowest print of the year but remains contained, which argues dealers are still net long gamma into the print and should mute any initial CPI overshoot unless the number surprises hard.
The risk: a hot CPI print alongside sticky Hormuz tensions is the combination that flips this from an orderly pre-data pause into a real gamma-unclench selloff, since long-gamma dampening only works while realized moves stay small.
