S&P 500’s Humming Profit Engine Can Keep Powering Stocks Rally

A solid earnings season shows Corporate America’s profit engine is humming along, potentially easing worries that the record-setting rally in US stocks is starting to overheat.

With about a third of S&P 500 Index members reporting by Thursday’s close, this earnings cycle is turning out to be much more robust than expected. Around 83% of companies have exceeded analysts’ profit estimates, according to data compiled by Bloomberg Intelligence. That’s on track for the highest share of beats since the second quarter of 2021.

The S&P 500 is up 28% since hitting a low on April 8, setting a series of record highs over the past few weeks. Even a version of the US benchmark that weights all members equally, rather than by market value, has notched a record. Those advances have come as fears about the impact of tariffs on the economy ebbed and investors slowly returned to stocks, abandoning an extreme aversion to risk.

For the gains to persist, corporate earnings will need to keep impressing investors, and Mark Hackett at Nationwide says the earnings season is pointing in that direction.

“As some of the pessimistic scenarios are fading, management commentary is less conservative and estimates for 2025 and 2026 are beginning to increase, which provides that tailwind,” said the firm’s chief market strategist.

Several major companies have been upbeat. Alphabet Inc. saw demand for artificial intelligence products boosting quarterly sales. Homebuilders D.R. Horton Inc. and PulteGroup Inc. reported better-than-expected earnings, sparking a relief rally in the stocks. Netflix Inc. raised its forecast for full-year sales and profit margins. And Levi Strauss & Co. said it expected sales growth to outweigh the effect of tariffs.
