US stocks opened higher on July 20, with the Nasdaq Composite leading gains as semiconductor and memory stocks rebounded sharply from recent selloffs.
The Nasdaq Composite rose 0.83% at the open, while the S&P 500 added 0.56% and the Dow Jones Industrial Average gained 0.30%, as a broad rally in chip stocks lifted technology shares.
"The bounce is largely mechanical — traders are cycling back into semiconductors after Monday's sharp drawdown, with the highest-beta names seeing the strongest recovery bids," said a New York-based equity strategist. "The move is technical, not driven by company-specific news."
SK Hynix led the rally with a 4.15% gain, followed by Micron Technology at 3.99% and SanDisk at 3.78%. Advanced Micro Devices climbed 3.54%, Intel added 2.63%, and Broadcom rose 2.25%. Among other chip names, Nvidia gained 1.5%, Taiwan Semiconductor Manufacturing Co. added 1.85%, ASML rose 2.19%, Lam Research climbed 2.76%, and ARM Holdings advanced 2.27%.
The rally follows a volatile week for technology stocks, with the iShares Semiconductor ETF dropping sharply on Monday before recovering. The rebound comes as investors look ahead to key earnings reports, including AMD's Q2 results scheduled for Aug. 4, which will test whether the AI-driven demand narrative can sustain the sector's elevated valuations.
The move tracked a broader improvement in risk appetite, with the Cboe Volatility Index edging lower from elevated levels. The U.S. 10-year Treasury yield held near recent ranges, while the dollar index remained steady, providing a supportive backdrop for equities.
