Dell Technologies (NYSE:DELL) shares are up 5% to $568.52, extending a 356% year-to-date advance, while Super Micro Computer (NASDAQ:SMCI) stock gains 3% to $36.87, and Hewlett Packard Enterprise (NYSE:HPE) stock rises to $57.25. This surge in server stocks is attributed to strong demand for data center hardware, with buyers shrugging off Silver Lake's latest Form 144 filing to sell 80,010 Dell Class C shares. The iShares U.S. Technology ETF (NYSEARCA:IYW) is up 0.84%, and the SPDR S&P 500 ETF Trust (NYSEARCA:SPY) is up 0.36%, indicating technology is outperforming the broader market, led by server names. A Federal Reserve rate decision later today is considered the session's biggest risk, as a hawkish surprise could reverse these gains.
