Major U.S. stock benchmark indices ended lower on Wednesday as investors processed the latest consumer inflation report.

Despite the broad market downturn during regular trading hours, several stocks experienced notable price movements after the market close.

In extended trading, Sanmina Corp. (SANM) rebounded over 7% following an 8.25% loss during the regular session, buoyed by investor enthusiasm for its artificial intelligence business segments. Keysight Technologies (KEYS) advanced more than 4% after ending regular trading down 3.4%, driven by the launch of new AI data center infrastructure products at the OCP Global Summit. Meanwhile, Assurant (AIZ) slid 2.9% after hours due to low-volume liquidity and profit-taking, paring back its 2% gain from earlier in the day.

During regular trading, top gainers included UnitedHealth Group Incorporated (UNH), Dollar Tree, Inc. (DLTR), and Moderna, Inc. (MRNA), which each rose more than 4.6%.
