On September 15, Marvell Technology rose 3.34% in regular trading, trading at $225.89/share, with turnover of $592 million. The stock rebounded sharply after the prior session's 7.32% plunge, which was part of a broad semiconductor selloff that sent the Philadelphia Semiconductor Index down 5.86%.

On the news front, semiconductor stocks staged a collective rebound following remarks by the U.S. President, who dismissed AI safety concerns as a \"hoax\" during a call with NVIDIA CEO Jensen Huang at the All-In Summit, comparing data centers to \"oil of the next 20 to 30 years\" and calling them more important than the internet. Separately, Citi released a report characterizing the recent semiconductor pullback as a rare buying opportunity, arguing that market fears of an AI spending slowdown are significantly overblown. The firm noted that continued growth in AI inference demand, coupled with persistent supply tightness, should support further capital investment expansion across the ecosystem.

Across the broader semiconductor sector, chip stocks rose in tandem, with Intel up 2.71%, AMD up 3.41%, Qualcomm up over 3%, and NVIDIA up 1.07%.
