Why Marvell Technology (MRVL) is Back on Investors’ Radar

Marvell Technology (MRVL) has come back into focus after a sharp share price move over the past month, with the stock showing a return of about 62% alongside strong longer term total returns.

That sharp 61.5% 30 day share price return and 83.3% 90 day share price return, alongside a 161.9% 1 year total shareholder return, suggest strong momentum even after the recent 3.1% 1 day pullback to US$153.25.

With Marvell now at US$153.25 and sitting at a premium to the average analyst price target of US$128.36, the key question is simple: is this momentum justified by current fundamentals, or is the market already pricing in future growth?

Most Popular Narrative: 1.4% Undervalued

Marvell's most followed narrative pegs fair value at about $155.37, only slightly above the last close at $153.25, so the recent surge sits right on that thesis.

Marvell Technology has executed a masterclass in capital allocation. In Q3 Fiscal 2026, they did two things that fundamentally alter the investment thesis: they sold their lower-growth Automotive Ethernet business for $2.5 Billion cash, and announced the acquisition of Celestial AI. This is a clear signal that Marvell is going "All-In" on AI Data Center Infrastructure. With record quarterly revenue of $2.075 Billion (+37% YoY) and guidance accelerating, Marvell is solidifying its position as the critical "plumber" of the AI era, controlling how data moves between Nvidia's GPUs.

The narrative leans heavily on AI data center demand, higher margins from optical interconnects, and a richer earnings multiple. It will be important to understand which specific growth and profitability assumptions support that valuation.

Result: Fair Value of $155.37 (ABOUT RIGHT)

However, this story can break if AI data center spending slows or if integrating Celestial AI and refocusing after the auto sale proves more complex than expected.

Another View: Multiples Point to a Richer Price

That 1.4% undervaluation narrative sits awkwardly beside Marvell's current P/E of 50.2x. This is higher than both its 41.6x fair ratio and the US Semiconductor industry average of 49.2x, even though it is below the 65.7x peer average. For you, that gap is either valuation risk or a premium you are comfortable paying.

Next Steps

Given that mix of optimism and concern in the story so far, this is a good time to look at the underlying data yourself and decide how comfortable you are with the trade off between growth hopes and valuation risk, then weigh up the 2 key rewards and 2 important warning signs
