Stock Market & Commodities

The S&P 500 finished essentially flat at ~7,764–7,765 (near its all-time high, ~0.4% below). The Dow Jones fell ~0.36% to ~51,864. Financials lagged (e.g., JPMorgan and Wells Fargo down >3%), while some software/consumer names dipped on concerns about competition from Meta’s Muse AI agent. Volume was heavy.[1]

•Oil falls below $100/barrel: Brent crude dropped for a fifth straight day, briefly under $98 and settling around $99.25 (down ~1%), on hopes of de-escalation in the U.S.-Iran conflict (possible Strait of Hormuz reopening within days if pressure eases) and Saudi pipeline repairs. WTI also eased. Diesel prices remain elevated/record-high in places.
