NEW YORK  — U.S. stock indexes are drifting on Monday following their sharp losses from last week.

The S&P 500 was up 0.1% in afternoon trading after flipping between small gains and losses through the morning. The relatively modest moves follow its 1.7% tumble on Friday, which followed several reports on the U.S. economy that came in weaker than expected.

The Dow Jones Industrial Average was up 192 points, or 0.4%, as of 1:01 p.m. Eastern time, and the Nasdaq composite was 0.3% lower.

Berkshire Hathaway’s Big Gain

Berkshire Hathaway climbed 3.9% for one of the market’s bigger gains after Warren Buffett’s company reported a jump in operating profits for the latest quarter. But even there, the good news came with a bit of caution.

The owner of Geico, BNSF railroad and other businesses said over the weekend that it’s sitting on a mountain of $334.2 billion in cash. Such a large amount could indicate Buffett, who’s famous for buying stocks when prices are low, may not see much worth purchasing in a market that critics say looks too expensive.

Starbucks rose 1.4% after saying it would cut 1,100 corporate jobs and leave several hundred more positions unfilled as new CEO Brian Niccol tries to make it a leaner operation.

They helped offset a 1.6% drop for Domino’s Pizza, which reported results for the latest quarter that just missed analysts’ expectations. Its international operations were a standout, but a closely tracked sales trend weakened for corporate-owned U.S. stores.

Big U.S. companies have broadly been reporting better profits for the last three months of 2024 than analysts expected, which is one of the main reasons the S&P 500 set a record before sliding at the end of last week. The pace of reports will slow this week, but several potentially market-moving updates are still on deck.

More Company Reports Coming This Week

Chief among them is Nvidia, the company that’s become one of Wall Street’s most influential stocks because of what had been nearly insatiable demand for its chips. Wednesday will be the company’s first profit report since a Chinese upstart, DeepSeek, upended the artificial-intelligence industry by saying it developed a large language model that can compete with big U.S. rivals without having to use the top-flight, most expensive chips.

That called into question all the spending Wall Street had assumed would go into not only Nvidia’s chips but also into the whole ecosystem that’s built up around the AI boom, including electricity to power large data centers.

Nvidia’s stock bounced between gains and losses through Monday morning, helping to pull the S&P 500 and other indexes up and down in its wake. It was virtually unchanged in midday trading.

Other big profit reports due this week include Home Depot’s on Tuesday and Salesforce’s on Wednesday.

In the bond market, Treasury yields were edging lower ahead of the upcoming reports. The yield on the 10-year Treasury slipped to 4.40% from 4.43% late Friday.

In stock markets abroad, German stocks ticked higher, and the DAX advanced 0.6% after political conservatives won an election dominated by concerns about Europe’s largest economy.

Indexes were lower across much of the rest of Europe and Asia. France’s CAC 40 fell 0.8%, Hong Kong’s Hang Seng slipped 0.6% and Japan’s market was closed for a holiday.
