For questions about this article or underlying research, email help@trefis.com.
Marvell Technology (MRVL) stock rose 9.3% on Wednesday, November 11, 2026, while the S&P 500 gained 1.3%. The company released no earnings report around the move. The stock advanced on a day when 32 of the 34 other semiconductor companies worth $2 billion or more also rose. So what was the market reacting to that day, and how much of Marvell’s business does it touch?
Marvell Sells Mostly To Data Centers
U.S. stocks rose on November 11 after CoreWeave’s earnings update eased worries that artificial-intelligence profits would not come soon enough to cover the debt taken on to build AI infrastructure. CoreWeave, a cloud provider, had been at the center of those AI jitters, and its earnings met expectations.
That worry focuses on the AI build-out, and data centers represent most of what Marvell sells. Its data center business made up 79% of revenue in fiscal Q2 2027, the quarter ended August 1, 2026, and grew 46% from a year earlier. On the August 27 call, management said AI demand for its products continues to rise. The company tied its custom silicon business to the AI infrastructure build-out.
Did Marvell Rise More Than Other Chip Stocks?
More than most. Marvell moved with its group but further than the typical chip stock: the median gain among the 34 other semiconductor companies worth $2 billion or more was 5.8%, and 20 of them rose 5% or more. The technology sector fund XLK gained 3.2%. All five companies on Marvell’s peer list rose by less, with Intel’s 7.5% the largest gain among them. The five are Broadcom, NVIDIA, Advanced Micro Devices, Qualcomm and Intel. Micron Technology, one of the five largest companies in the group, rose 11.9%, more than Marvell.
Where Does Marvell Stock Stand Now?
A rise this large is not rare for Marvell. The stock recorded 10 of them in the prior 365 days, the latest a 9.5% gain on November 9. The swings have run both ways, including a 16.4% fall on November 5. Over the past month, from October 13 to November 11, the stock lost 37.2%, against a 2.3% drop for the S&P 500.
Over twelve months the stock looks very different. Marvell returned 81.4%, against 12.8% for the S&P 500. Even so, its $168.80 close sits well below its 52-week closing high of $316.43, set on June 4, 2026. The stock trades at 16.0 times sales, against 3.2 times for the S&P 500.
Marvell is expected to report its fiscal third-quarter 2027 results later in November 2026, and data center revenue is the figure to watch.
