Dow drops 454 points as Hormuz deal doubts weigh on stocks

The Dow Jones Industrial Average fell 453.64 points, or 0.83%, to 53,895.48, halting a five-day winning streak as doubts over a Strait of Hormuz reopening deal weighed on markets. The S&P 500 slipped 0.18% to 7,709.99, while the Nasdaq Composite edged down 0.04% to 26,352.45.

"There's a little bit of headline fatigue around Iran," said Robert Bernstone, a partner at SummitTX Capital. "The market has been pricing in a deal for days, and now the details are getting murkier."

The Dow's decline was amplified by its price-weighted methodology, with six stocks accounting for roughly 81% of the index's 503-point intraday drop. Goldman Sachs fell $27.83, subtracting about 165 points from the index, while UnitedHealth dropped $9.60, Boeing lost $8.33, Caterpillar declined $8.31, Honeywell International slipped $7.25, and Salesforce fell $7.17. Microsoft added $10.72, Chevron gained $3.06, and Walt Disney rose $2.67, partially offsetting the losses. Twenty-two of the Dow's 30 components finished lower.

Semiconductors led sector gains, rising 3.1% as SiTime jumped 21.4% and Diodes advanced 18.8% after strong earnings, while television and radio shares gained 2.9%. Education and training services fell 6.2%, the worst sector performer, with Universal Technical Institute sliding 33.1% and Chegg down 15.3%. Waste management stocks dropped 4.6%.

Oil prices rebounded as Hormuz uncertainty resurfaced, with WTI crude climbing 2.75% to $77.29 a barrel and Brent gaining 3.83% to $82.49. The 10-year Treasury yield rose to 4.67% from 4.63%, while the dollar index gained 0.17%. Gold held above $4,300 at a seven-week high.

The jittery session came despite an earnings season in which 84.8% of the 382 S&P 500 companies that have reported beat expectations, well above the historical average of 68%. Honeywell Aerospace, trading as a standalone company, plunged 21% after cutting its 2026 organic sales growth forecast to 4%-5% from 7%-9%, while AppLovin sank about 20% after missing revenue estimates and Datadog fell 14% after a key AI client flagged softer second-half activity.

Friday's jobs report looms as the next catalyst

Economic data released this week offered conflicting signals. ADP private payrolls rose 44,000 in July, well below the 75,000 consensus, while initial jobless claims came in at 199,000 versus a 204,000 forecast. ISM services slipped to 54.1 from 54.0, and Q2 productivity rose 1.4%, above the 0.6% estimate. The median forecast for Friday's nonfarm payrolls report calls for 83,000 jobs added, up from 57,000 in June, with unemployment expected to hold at 4.2%.

"A significant payroll shock has the potential to shift rate forecasts," said Clark Bellin, chief investment officer at Bellwether Wealth. "August is typically a volatile month for stocks, and with Hormuz still unresolved, the market is vulnerable to headline risk."

July consumer price data is due Wednesday, followed by producer prices Thursday and retail sales Friday. Any disruption in Hormuz shipping could push crude prices higher and renew inflation concerns, complicating the Federal Reserve's rate path.
