Marvell Technology Stock Reaches Record High: Is It Still a Buy?

Marvell Technology has emerged as one of the standout chip stocks of 2026, with its shares climbing more than 130% since the start of the year and reaching a new all-time high. The rally has been fueled by strong demand for custom chips, an area where Marvell helps companies reduce reliance on Nvidia’s costly products. As more businesses look to diversify their artificial intelligence infrastructure, Marvell has positioned itself as an important supplier in the expanding data center market.

The company’s latest quarterly results added to investor optimism. For the first quarter of fiscal 2027, Marvell reported net revenue of $2.4 billion for the period ended May 2, a 28% increase from the prior year. While that pace may not match the fastest-growing AI names in the market, management said growth is expected to accelerate through the rest of the fiscal year. Chief Executive Officer Matt Murphy said the company expects revenue growth to continue accelerating each quarter in fiscal 2027, supported by strength in its data center business. For the current quarter, Marvell forecast revenue of about $2.7 billion, which would represent roughly 35% year-over-year growth.

A key part of Marvell’s long-term opportunity is its growing relationship with Nvidia. The company’s products are expected to integrate with Nvidia’s NVLink Fusion rack-scale platform, potentially expanding Marvell’s role in next-generation AI systems. That partnership could create additional demand and strengthen Marvell’s position in high-performance computing and data center networking.

Despite the strong business momentum, concerns are rising around valuation. Marvell is now trading at about 70 times trailing earnings and more than 50 times forward earnings, making it expensive compared with the broader market. By contrast, the average S&P 500 stock trades at around 26 times trailing earnings and about 22 times forward earnings. The gap suggests investors are paying a steep premium for Marvell’s growth potential.

The article argues that while Marvell has attractive opportunities ahead, especially in AI infrastructure and through closer collaboration with Nvidia, the stock may already reflect much of that optimism. At current levels, the margin of safety appears limited, which could make the shares vulnerable if growth slows or expectations become harder to meet.

For investors, the question is not whether Marvell is a quality business, but whether the stock is still reasonably priced after its dramatic rally. The conclusion is cautious: Marvell may continue to grow, but the valuation may now be too rich for new buyers seeking a better risk-reward profile.
