Stock Market Today: S&P 500, Nasdaq Hit Records as Oil Shock Tests Big Tech Rally

U.S. stocks extended their record streak Monday, though the gains weren’t universal. The S&P 500 edged up 8.83 points, or 0.12%, settling at 7,173.91. The Nasdaq Composite tacked on 50.50 points, or 0.20%, to close at 24,887.10. The Dow Jones Industrial Average, however, gave up 62.92 points—down 0.13%—ending at 49,167.79.

It’s all about the timing. With a packed roster of Federal Reserve and other central-bank meetings, key U.S. growth and inflation figures, plus results from the biggest tech names, investors are staring down a loaded week. This comes after a surge that’s driven the S&P 500 close to its best month since the pandemic’s low point.

Oil has turned into the wildcard inside that trade. Brent—the global crude yardstick—finished 2.8% higher at $108.23 a barrel. West Texas Intermediate, the main U.S. contract, gained 2.1% to reach $96.37. Peace talks between the U.S. and Iran hit a wall, and shipping volumes through the Strait of Hormuz, the Gulf’s critical oil artery, remained tight.

No signs of panic in the market today. John Praveen, co-chief investment officer at Paleo Leon, noted that investors appeared to expect a resolution “sooner or later.” Phil Blancato, chief market strategist at Osaic Wealth, described it as a “holding-on moment” with traders looking ahead to upcoming earnings and economic numbers.

Pressure’s on Big Tech to deliver. With Microsoft, Alphabet, and Amazon lined up to report this week, investors are zeroed in on capital spending—those big-ticket investments in data centers, chips, and other infrastructure. The trick: finding clear evidence that the artificial-intelligence boom is still feeding earnings.

Nvidia surged 4% to a record high, a clear sign that enthusiasm for AI stocks hasn’t faded. For Microsoft, Alphabet, and Amazon, the stakes just got higher—impressive sales numbers alone might not satisfy investors if expense projections climb or if there’s any hint of weaker cloud demand.

Chris Senyek at Wolfe Research says conflicting headlines out of Iran are pushing investors to focus more on earnings. This week, he described it as a “firehose” of data—oil, rates, tech margins, guidance—all in play at the same time. SWI swissinfo.ch

Stock action was mixed. Verizon climbed as it reported stronger-than-expected earnings and, for the first time since 2013, ended a first quarter with net gains in postpaid phone subscribers. Domino’s Pizza, on the other hand, dropped after disappointing results and a lowered guidance.

Domino’s delivered a note of caution that didn’t quite fit with the broader index highs. “Pressure intensified” over the quarter, Chief Executive Russell Weiner said, pointing to consumer hesitation and inflation’s impact on spending, per an Investopedia transcript. Investopedia

The worry: oil could fade from headlines and turn into a bigger inflation headache. Tamas Varga of PVM Oil Associates points to the diplomatic deadlock holding back millions of barrels each day, saying there’s “only one direction” for crude prices to go. Over at Goldman Sachs, Daan Struyven and his team argue that “economic risks are larger” than what crude price forecasts are picking up. Reuters

That channel’s getting plenty of attention from bond traders. The 10-year Treasury yield climbed to 4.336%, while investors are eyeing the March Personal Consumption Expenditures Price Index—yes, that’s the Fed’s go-to inflation measure—due later this week. When oil prices push higher, central banks get less breathing room to cut rates, since fuel and transport costs creep up.

At this stage, stocks aren’t behaving as if they’re prepared to surrender the rally. Instead, traders want evidence—from the Fed, from oil negotiators, and from the companies that pushed the index to all-time highs.
