US technology stocks rallied in pre-market trading on Tuesday, with semiconductor and optical communication shares leading the gains after another strong earnings report in the sector fueled optimism around the artificial intelligence buildout.
"This was the single best quarter that I have seen from the semiconductors," CNBC's Jim Cramer said of Qnity Electronics's results, which sent the stock to a new all-time high and lifted peers across the industry.
The gains were widespread among chip-related names. Memory-chip maker Micron Technology Inc. rose over 5%, with similar gains seen in SanDisk. Optical components manufacturer Lumentum Holdings Inc. and Applied Optoelectronics Inc. both climbed more than 4%, while chip giants Intel Corp. and Qualcomm Inc. advanced nearly 4% and 3%, respectively. AI bellwether Nvidia Corp. added almost 2% in pre-market action. The buying pushed the tech-heavy Nasdaq 100 up more than 1%, according to data from Wednesday's session.
The rally underscores the intense investor demand for companies exposed to the buildout of AI infrastructure. The sector has been a standout performer this earnings season, with the latest results from Qnity, a key supplier of specialized materials for chip manufacturing, providing fresh impetus. The company's stock has now doubled year-to-date.
Earnings Fuel Tech Rally
Qnity Electronics delivered a stellar first quarter, with revenue increasing 17.6% from a year ago to $1.32 billion, beating the $1.27 billion expected by analysts. Earnings per share jumped 33.3% to $1.08, also outpacing consensus estimates of 92 cents. The company, a spinoff from DuPont, plays a critical role in the data center supply chain, providing chemicals and materials for manufacturing and packaging semiconductors for customers like TSMC, Samsung, and SK Hynix.
On the company's earnings call, CEO Jon Kemp noted that as the industry runs out of room to shrink chips, it is now stacking them to increase power and efficiency—a trend that will only make Qnity's advanced materials more essential. Management raised its full-year guidance for sales and profit, signaling expectations for continued strength.
The positive sentiment extends beyond just Qnity. Advanced Micro Devices Inc. and Super Micro Computer Inc. both rallied double-digits on Wednesday after crushing their own analyst estimates, as noted in market reports. Separately, Nextracker Inc. (referred to as Nextpower in initial reports) saw its stock jump 10% after the solar technology company announced record revenue for its 2026 fiscal year.
The tech-sector enthusiasm is being amplified by a more favorable macroeconomic backdrop. Oil prices tumbled Wednesday on reports of a potential peace deal between the US and Iran, with Brent crude, the international benchmark, plunging as much as 9%. The drop in energy costs is easing inflation fears and prompting investors to move back into riskier assets like equities.
