Marvell Technology rocketed 14% Tuesday after rolling out fresh AI memory gear at the Flash Memory Summit in Santa Clara. The company unveiled its Bravera SC6 controller, Structera X expansion products, and something called Photonic Fabric that lets data centers pool memory across multiple AI racks. That last piece could handle 32 terabytes of shared memory while pumping out three times the token throughput without needing more power or floor space. Investors took notice.
The semiconductor sector as a whole caught fire. The SOXX chip ETF climbed nearly 7%, dragging the S&P 500 and Dow toward fresh records. Micron jumped over 8%, SK Hynix matched that, Intel popped 11%. Even Nvidia, the usual mega-cap star, only managed 2.5% in the noise. AMD tacked on more than 8% ahead of earnings that dropped after market close Tuesday.
This rebound matters because the sector had taken a proper beating. The PHLX Semiconductor Index tanked more than 20% from its peak during a brutal July. Traders had panicked about whether Big Tech would actually keep spending on AI infrastructure, and whispers about Chinese competition spooked the crowd. One month of selling can do that. A single product announcement with real numbers 32 terabytes, three times throughput flipped the script back.
