Wall Street kicked off the week on the back foot as rising geopolitical tensions and resurfacing inflation fears sapped risk appetite. The S&P 500 fell 0.52% to 7,745.06, while the Dow Jones dropped 0.51% to 53,459.78 and the Nasdaq limited its losses to 0.32% to close at 26,644.91. Small-caps also stumbled, with the Russell 2000 retreating 0.35% to 3,057.54. The VIX volatility index jumped 6.60% to 15.19 amid climbing oil prices and a 10-year Treasury yield that hit 4.72%.

Sectors in focus:

• Energy & Safe Havens: WTI Crude surged 3.07% to $84.93 a barrel after Iran threatened regional escalation if U.S. diplomacy fails, sparking fears of a Strait of Hormuz closure. Gold also caught a haven bid, climbing 0.80% to 4,472.6.
• AI Infrastructure: Strong Q3 results from Applied Materials and a massive $190B-$200B revenue forecast from Anthropic bolstered AI sentiment. This drove market-leading gains in Special Industry Machinery, NEC (+3.44%) and Computer Storage Devices (+2.81%).
• Industrials & Instruments: Laboratory Analytical Instruments tumbled 6.26% to lag the market, while Air Transportation, Scheduled dropped 3.25%. Adding to broader industrial pressure, L3Harris fell 4.6% following the sudden exit of CEO Christopher Kubasik.

On the radar: Investors remain highly cautious ahead of a crucial retail earnings parade to gauge consumer health following a weak July retail sales print (-0.6%).
