Dow tops 54,000 as earnings and oil slide fuel record rally

The S&P 500 closed at a record Tuesday as blowout earnings and a crude slide on Hormuz deal hopes fueled a broad rally.

The S&P 500 rose 1.79% to a record 7,736.52 as earnings and a slide in oil on Hormuz deal hopes lifted the Dow above 54,000.

"We may be reaching a pinnacle of sorts in earnings and economic momentum, and investors are struggling with what comes next," said Callie Cox, chief market strategist at Ritholtz Wealth.

The Nasdaq Composite climbed 2.59% to 26,584.99, while the Dow surged 907.47 points, or 1.71%, to 54,085.88 — its fourth straight gain and biggest single-session advance since June. Technology shares jumped about 4%, with the Philadelphia Semiconductor Index up roughly 6%, while industrials and materials each rose nearly 2%. Financials added 1%, led by Goldman Sachs, which gained more than 3.4%.

Palantir Technologies surged 29.4%, its strongest day in more than two years, after the data analytics company beat second-quarter estimates and raised its full-year revenue forecast. Semiconductor names extended their recovery from July's losses, with Micron Technology up 7.6% and Marvell Technology advancing 12.8%. Caterpillar rose 5.4% after reporting results above expectations and lifting its revenue growth outlook, citing strong demand for equipment used in AI data-center expansion. Amazon fell 2.3%, a day after its market value topped $3 trillion for the first time, following a regulatory filing showing founder Jeff Bezos planned to sell about $4 billion of shares.

Crude tumbled after Treasury Secretary Scott Bessent said Washington and Tehran were holding talks and could reach an agreement as early as Tuesday or Wednesday to reopen the Strait of Hormuz. West Texas Intermediate settled 6.4% lower at $75.20 a barrel, while Brent dropped 6% to $78.85. President Donald Trump said a deal was possible as early as Wednesday. European markets also closed higher, with the Stoxx Europe 600 rising 0.73% to a record 656.86 and Spain's IBEX 35 closing above 20,000 for the first time.

Concentration Risk Lingers

The rally rests on a narrow base. The 10 largest S&P 500 companies now account for roughly 38% of its total value, about 10 percentage points above the dot-com era peak, according to FactSet data. The same concentration that powered the rebound makes it fragile — in early June, the seven largest stocks shed around $2 trillion in a matter of weeks, dragging the index lower even as hundreds of smaller companies held steady. The risk surfaced again after the bell Tuesday, when SpaceX fell as much as 8% after its first earnings report since its June IPO showed capital spending climbed to $18.4 billion in the second quarter, and AMD dropped about 8% after results only edged past forecasts.

Attention turns to ADP's private payrolls report Wednesday and the July jobs report Friday, with sticky inflation fueling bets that the Federal Reserve under new Chairman Kevin Warsh holds rates steady or raises them. Higher rates tend to squeeze the richly valued tech names now carrying the market, so a strong jobs print Friday would reinforce the hold-steady view while a soft one could revive hopes for cuts.
