S&P 500 futures are little changed after index notches back-to-back closing records: Live updates

Stock futures are near flat Tuesday night as investors questioned whether the S&P 500 could continue trading around all-time highs with big tech earnings kicking off.

Dow Jones Industrial Average futures gained 46 points, or 0.1%. S&P 500 futures sat near flat, while Nasdaq 100 futures ticked down 0.1%.

Those moves follow a second straight day concluding at a high for the S&P 500, which inched up 0.06% in the session. Tuesday marked the 11th closing record of 2025 for the benchmark index. The 30-stock Dow climbed nearly 180 points in the session. The tech-heavy Nasdaq Composite, on the other hand, fell about 0.4% as chip stocks took a hit.

“There's not a lot of optimism,” said Ryan Detrick, chief market strategist at Carson Group, on CNBC's “Closing Bell.” But, “we said there'd be a summer rally. It wasn't popular. It's happening. We think it's not over yet,” he added.

Investors are awaiting earnings from Alphabet and Tesla expected Wednesday after the bell. They are the first reports of the earnings season from the megacap technology sector, a group that's been closely watched given its market leadership in recent years.

Beyond big tech, investors will also monitor reports from Hasbro before the bell, followed by Chipotle Mexican Grill and Mattel after the market closes. These releases come amid a busy earnings week. Of the approximately 17% of S&P 500 companies that have reported so far this season, about 85% have posted earnings that surpassed Wall Street's expectations.

On the economics front, traders will follow existing home sales data due Wednesday morning.

Health care, a 2025 laggard, puts up a strong showing Tuesday

The sleepy health-care sector, which is off 3% in 2025, was the big winner on Tuesday.

Health care rose 1.9% on Tuesday while investors took a step back from tech names. The information technology sector lost 1% during the session, dragged lower by losses in Nvidia and Broadcom.

IQVIA emerged as the leader in the health-care sector on Tuesday, leaping nearly 18% and posting its best day ever – dating back to its 2013 initial public offering as Quintiles. Shares of the health information technology company rose on the heels of a second-quarter beat on the top and bottom lines.

Charles River Laboratories and Quest Diagnostics also posted solid performances in the session, up 9% and 7%, respectively.
