Marvell hits a new high—valuation looms over AI chips

Marvell stock – Marvell Technology’s stock surged more than 130% this year to a new all-time high after a strong quarter and upbeat fiscal guidance. But the rally has pushed its valuation to levels that leave investors little margin of safety.

By the time the ticker flashed another record, the story was already written in the price. Marvell Technology (NASDAQ: MRVL) is one of the hottest chip stocks discussed in 2026. and this week it reached a new all-time high after a run that has pushed shares up more than 130% since the start of the year.

The company makes technology that helps businesses develop custom chips—work that has mattered as firms look to diversify and become less dependent on Nvidia’s high-priced chips. Now. Marvell is being pulled deeper into the AI supply-chain conversation. and the question on many traders’ screens is whether the momentum is about to meet its ceiling.

Last week, Marvell reported its first-quarter earnings for Fiscal 2027. For the period ended May 2, the company posted net revenue of $2.4 billion, up 28% from a year ago. Management’s message was that growth is not slowing down; it’s accelerating.

CEO Matt Murphy said, “We expect revenue growth to continue accelerating each quarter throughout fiscal 2027, driven by continued strength in our data center business.” For the current quarter, Marvell projected revenue around $2.7 billion, a year-over-year increase of about 35%.

There’s also a forward-looking hinge that investors are watching: Marvell’s partnership with Nvidia and the ability of Marvell’s products to integrate with the rack-scale platform NVLink Fusion. The company framed that as a way to open up additional growth opportunities.

But for all the optimism on the earnings call, the debate has shifted to what price is already assuming.

Marvell is trading at around 70 times its trailing earnings. Its forward price-to-earnings multiple is still above 50—based on earnings the business may generate in the year ahead using analyst expectations. By contrast. the average S&P 500 stock trades at 26 times trailing earnings. and on a forward earnings basis that multiple is 22.

That gap is where risk starts to creep in. The stock may have strong growth ahead. the argument goes. but at these valuation levels. investors may be stretching expectations too far. The result. according to the view presented here. is little margin of safety—meaning even a good company can become a difficult buy if the price has already priced in the best outcomes.

And the timing of this question matters: the stock’s surge this year has coincided with the company hitting new highs, which means investors are not just evaluating fundamentals—they’re also trying to judge whether the market is already moving faster than the numbers.

A separate note adds another layer to the broader investing mood around Marvell. The Motley Fool Stock Advisor analyst team identified what it believes are the 10 best stocks for investors to buy now. and Marvell Technology wasn’t one of them. The same material references past list moments: Netflix made the list on December 17, 2004, and Nvidia made the list on April 15, 2005. It says that if $1. 000 had been invested based on those recommendations. it would have grown to $463. 900 for Netflix and $1. 294. 401 for Nvidia. and it states that Stock Advisor’s total average return is 978% compared with 211% for the S&P 500. with returns as of June 1. 2026. David Jagielski. CPA “has no position in any of the stocks mentioned. ” while The Motley Fool has positions in and recommends Marvell Technology and Nvidia. following its disclosure policy.

For now, Marvell’s story remains a split screen: accelerating business momentum on one side, and a valuation that leaves investors weighing how much risk they’re willing to carry when the stock is already priced for success.
