Marvell Technology fell roughly 10% Tuesday, wiping out gains for one of this year’s top AI chip names. The drop came just a day after Marvell joined the S&P 500.
The stock traded at $276.82 in the afternoon, off $31.04 from where it closed Monday. Earlier, shares hit a low at $276.11. Around 29 million shares changed hands during the session. Market cap was near $247 billion.
S&P Dow Jones Indices put Marvell in the S&P 500 ahead of the open Monday, June 22, swapping it for Pool Corp. The S&P 500 acts as the main U.S. stock benchmark that many index funds mirror, so names added can see flows from those funds. But that flow didn’t stop shares from dropping Tuesday.
Chip losses hit Nasdaq, S&P 500 as AI spending questioned The drop wasn’t limited to Marvell. The Nasdaq and S&P 500 both slid to their lowest in over a week after investors cut exposure to semiconductor names and raised doubts about future AI infrastructure spending by big tech. Nvidia, Intel, Marvell, and AMD dropped from 3.8% to 9% in early trading, Reuters said. The Philadelphia Semiconductor Index shed 7.6%.
The market’s trade remains “highly concentrated and flow-driven” right now, Ross Mayfield, investment strategy analyst at Baird, said. That’s left it exposed to “relatively small shifts in sentiment.” Melissa Brown, managing director of investment decision research at SimCorp, said a backdrop of higher rates and more competition for capital could keep the market “more volatile.” Reuters
Marvell saw a strong run ahead of the index move, pushed by hopes for its data-center networking chips in the AI boom. The stock ended up more vulnerable as investors started to unload risk in the same stocks that had powered the market up.
Marvell’s latest numbers are giving bulls a reason to stay in. The chipmaker posted record fiscal first-quarter revenue of $2.418 billion, up 28% year over year, and set its second-quarter revenue outlook at $2.7 billion, midpoint. CEO Matt Murphy said Marvell is seeing “exceptional AI-related bookings” and expects revenue growth to pick up pace through fiscal 2027. Marvell Technology, Inc.
Networking is where the big bet is. KeyBanc’s John Vinh last week bumped his Marvell target up to $385 from $260, sticking with his Overweight. He said “networking represents the most significant and durable growth opportunity.” Optical transceivers, which convert electrical signals to light to move data in large AI data centers, use Marvell’s chips inside.

Broadcom, a key competitor in custom silicon and networking, slipped 3%. Nvidia fell almost 4%. Micron lost over 14% as selling in chip stocks spread out of just one corner of the sector. Micron’s upcoming earnings are under scrutiny for hints on AI-related memory chip demand.
Wall Street targets on valuation are mixed. Google Finance on Tuesday showed Bank of America’s Vivek Arya kept a Buy and a $365 price target. KeyBanc’s $385 target stayed higher than the share price, unchanged from last week. Still, the average target on Google was $261.62, trailing Tuesday’s quoted price.
Marvell has spelled out the risk. In its latest quarterly filing, the company warned that if AI-related capex drops sharply, results will probably take a hit. Its 10 biggest buyers made up 82% of net revenue for fiscal 2026, exposing Marvell to trouble if any of them delay, cut orders, or spend with rivals.
For now, Marvell isn’t getting the typical index-bump from its S&P 500 debut. The stock is trading more like an over-owned AI name. The real test comes after the S&P 500 flows are done, when demand depends on earnings, rates, and actual data center orders.
