- Samsung reported Q2 operating profit surging 19-fold on AI demand, but concerns about its AI spending plans and future demand spooked investors into a broader semiconductor sector sell-off.
- Nasdaq 100 futures (NQ=F) dropped 1% and S&P 500 futures (ES=F) fell 0.2%, while Dow Jones futures (YM=F) rose 0.2% — a divergence following Monday's record-setting session.
- The Dow Jones closed above 53,000 for the first time on Monday, a record high, as the S&P 500 and Nasdaq also gained amid renewed AI trade confidence following June's chip sell-off.
- Brent crude futures (BZ=F) rose above $72/barrel and WTI (CL=F) climbed to $69/barrel after reports of Iranian attacks on commercial ships in the Strait of Hormuz.
- Markets remained attuned to the risk that the US-Iran peace deal could break down, even as traffic through the Strait of Hormuz was gradually picking back up.
Why it matters: Samsung's 19-fold profit surge couldn't satisfy investors worried about its AI capex, exposing how fragile the chip rally has become — the Nasdaq 100 fell 1% in futures while the Dow rose 0.2%, and Brent's climb past $72 on Iran ship attacks reminded traders the US-Iran deal remains the market's key risk factor into year-end.
