Stock futures were lower Wednesday ahead of the Federal Reserve's decision on interest rates.
GE Healthcare Technologies led the S&P 500 ahead of the opening bell, rising 10%. The medical technology company reported higher sales and better-than-expected profit margins for the second quarter.
Bloom Energy, up 8%, also was rising sharply after earnings. Management guided for 2026 revenue to double from the prior year on the back of better-than-expected quarterly numbers.
Ford Motor jumped 4.6% after the auto maker posted a better-than-expected operating profit for the second quarter and raised its full-year outlook.
Seagate Technology added 4.1%. The data-storage company reported stellar earnings and revenue for its fiscal fourth quarter as the artificial-intelligence boom drove up demand for its products. Rival Western Digital also got a boost, advancing 1.9% in the premarket session.
Other companies weren't faring as well following their quarterly reports. Vertiv slumped 12% as the maker of data-center infrastructure posted second-quarter revenue below analysts' targets.
SoFi Technologies slumped 6.2%. Although CEO Anthony Noto spotlighted the "velocity" of the company's growth in the fintech's latest quarter, Wall Street remained unimpressed as earnings only beat estimates by a hair.
Humana fell 6.2%. The health insurer posted second-quarter earnings that were better than anticipated, but investors looked beyond those to focus on a higher medical cost ratio and reaffirmed adjusted earnings guidance.
SK Hynix slid 2.3% in the U.S. after the South Korean memory-chip maker missed Wall Street's second-quarter earnings target. Rival Micron ticked 0.6% lower. SK Hynix fared even worse in Seoul trading, finishing the session down 9.6%.
Procter & Gamble declined 2.6%. The consumer packaged goods giant, whose products range from hair care to laundry detergent, reported mixed quarterly earnings and issued underwhelming profit guidance.
More earnings are on the way: Facebook parent Meta Platforms and software giant Microsoft are both set to report after Wednesday's closing bell. Chip maker Qualcomm also is scheduled to report fiscal third-quarter earnings after the end of the trading session.
