Marvell Technology shares jumped roughly 7% in premarket trading Monday after S&P Dow Jones Indices said the chipmaker is set to join the S&P 500 later this month. The move puts new index demand behind one of the year’s more volatile AI chip names. Google Finance showed Marvell at $282.50 ahead of the open, up 7.22% from Friday’s finish at $263.47.
Marvell and Flex are joining the S&P 500 before the market opens on June 22, S&P Dow Jones Indices said. Pool Corp and The Campbell’s Company will be dropped from the index as part of the quarterly rebalance.
S&P 500 membership has an effect because it means passive index funds and ETFs need to buy the stocks that join the index. These funds track the benchmark and have to add the new names to line up with it, instead of picking their own stocks.
The S&P 500 is Wall Street’s standard for large-cap U.S. stocks, holding 500 big names and tracking around 80% of the U.S. market cap, according to S&P. For Marvell, getting in shifts the company’s standing, as it goes from a fast-moving AI play to an index name that shows up in most mainline U.S. equity portfolios.
Chip stocks found some footing, sending futures higher early. Reuters said Nvidia, Broadcom and Micron were up between 1.5% and 3.9% in premarket, while Marvell added 6.6%. At 6:07 a.m. ET, S&P 500 futures rose 0.35% and Nasdaq 100 futures gained 0.69%.
Marvell’s stock surged earlier this year, then quickly gave back gains. According to Reuters, shares had more than tripled this year, boosted by demand for AI, and were up about 29% for the week before the market closed on Friday. Nvidia CEO Jensen Huang called Marvell the “next trillion dollar company,” giving it another lift. Reuters
The company now plays a larger role in the AI infrastructure trade. It sells data-center chips and networking gear that move data within and between big computing systems. Larger competitor Broadcom is also in custom chips for cloud companies, a business getting more investor interest as Big Tech looks for alternatives to Nvidia’s expensive, hard-to-get AI processors.
Earnings are giving a boost. Marvell said on May 27 that fiscal Q1 revenue jumped 28% from last year to hit a record $2.418 billion. The chipmaker expects Q2 revenue to reach $2.7 billion at the midpoint. CEO Matt Murphy pointed to “exceptional AI-related bookings” and said Marvell is raising its revenue targets for fiscal 2027 and 2028. Marvell Technology, Inc.
Analysts had called the stock a disputed AI play ahead of the S&P announcement. J.P. Morgan’s Harlan Sur called Marvell a “battleground” because of rising chip and optical connectivity competition. Frank Lee at HSBC told MarketWatch/Dow Jones the market is still missing the size of Marvell’s optical revenue potential. Morningstar, Inc.
Sentiment is mixed. UBS Global Wealth Management CIO Mark Haefele told Reuters, “We do not expect investors to lose confidence in the AI outlook.” That followed a drop on concern that some chip stocks had gone up too quickly. Reuters
But the index bid doesn’t get rid of the risks. In its latest quarterly filing, Marvell called out a heavy reliance on a few big customers, concentration in the data-center business, macro risks like high interest rates, and trade curbs with China. The company also flagged demand forecasting troubles that could create excess inventory or not enough supply.
For Monday, the focus is straightforward. Marvell is getting picked up as it heads into an index tracked by a lot of funds. Investors are weighing if the AI growth pitch is enough for a stock that’s already priced high with optimism.
