Micron, Trade Desk, Western Digital: 2025’s Big Stock Movers
↘️ Trade Desk (TTD): The advertising-technology company is poised to be the S&P 500’s biggest loser in 2025. Shares have slid around two-thirds so far, their worst year on record. The company missed revenue estimates in February, and the stock was downgraded by analysts in August.
↗️ Western Digital (WDC): The data-storage stock has jumped over 280%, marking its best year ever and making it the S&P 500’s top gainer. Hard-drive makers have resurged as investors bet on AI driving demand for digital storage. Shares of rival Seagate Technology (STX) have soared roughly 225%.
↗️ Micron Technology (MU): Chip makers were investor darlings in 2025, propelled by the U.S.-China AI arms race and a capital-spending boom. Micron jumped nearly 250% through Tuesday. AMD (AMD) and Nvidia (NVDA) were both set for hearty double-figure percentage annual gains.
