The dominant theme is a sharp divergence in Big Tech earnings reactions: Amazon (AMZN) surged ~15% on record cloud growth (AWS +37% YoY, strongest in 4+ years) and a $600M tariff refund, while Apple (AAPL) plunged ~10% (worst day since March 2020) after Tim Cook warned of a '100-year flood' in memory pricing and guided September revenue growth of 9-11% below the ~12% consensus. This has flipped the world's most valuable company title back to Nvidia (NVDA), which rose ~2%. The AI trade narrative is bifurcating: hyperscalers with visible cloud monetization (AMZN, MSFT) are rewarded, while those with heavy capex and weak FCF (META, GOOGL) are punished. Memory-chip names (MU, SK Hynix) are volatile amid a hedge fund (Situational Awareness) forced-deleveraging narrative, but Micron and Sandisk are rebounding 5-9% today. Oil is rising ~1.5% (Brent ~$88, WTI ~$85) after Iran said it stopped two tankers in the Strait of Hormuz, with Brent on track for a 23% July gain; this is feeding inflation fears (US 10Y at 4.739%, highest since Jan 2025; euro-area inflation up to 2.9% on 10% energy). The Fed is now seen as 69% likely to hike in September, a hawkish repricing that pressures high-multiple tech and REITs. Geopolitically, the US-Iran conflict is ESCALATING: Trump claims Iran 'surrendered' but also says he's losing confidence in negotiators, Saudi Arabia is preparing a ground operation in Yemen, and Israel bombed Rafah even as Hamas agreed to a disarmament deal. The Hormuz oil-shuttling trade has picked up, partially offsetting supply fears. Tesla (TSLA) faces a new NHTSA investigation into 1.2M vehicles over suspension failures, a potential overhang. The S&P 500 is stuck at the 7,500 battleground; a break below 7,450 could trigger a larger downside move per options positioning.
