Semiconductor Market Commentary, Thru Project Mascot
Marvell's management is running the stock as a pump and dump to move shareholders' money into their own pockets. Wall Street prices Marvell as an ASIC design house without realizing that ASIC design is just IT outsourcing. It is not a real CXL play either: CXL IP is sold by Cadence, Synopsys and Rambus with no moat, and Astera Labs, which builds the switches and software around CXL, is the only good CXL play. x.comÂ
Lumentum's 109% year-on-year growth and sold-out capacity through 2029 make selling its AI optics exposure questionable. Bloomberg reported Marvell is in advanced talks to buy it; the appeal depends on the price, especially when holders of an $80 billion Lumentum would become holders of a $320 billion-plus Marvell growing 37%. x.comÂ
Marvell is expensive, growing more slowly and not founder-led, so owning it directly makes little sense. x.comÂ
Marvell's end-to-end networking approach is well suited to heterogeneous GPU, CPU and ASIC compute and mixed optical/copper technologies. Its shift from AI loser to winner deserves a lot of credit: its old custom-ASIC focus had lost out to Broadcom and Alchip, but it is now back in ASICs as Google's TPU v10 partner. The stock's excellent run reflects how it is now perceived. x.comÂ
Marvell's risk/reward is no longer favorable after the stock ran three to four times from the $70s in March, when it was the most obviously undervalued chip stock. Jensen Huang's call for a $1T company is partly driven by his dislike of Broadcom's Hock Tan, and the Celestial AI angle is overhyped relative to the value it adds. A bounce is likely from here, but there is no case for adding exposure at the current price. x.com x.com x.comÂ
Marvell is a loser from the AI-lab slowdown, because it can't earn premium margins if Nvidia and Broadcom also see a pause. Lab leaders including Elon Musk, Dario Amodei and Sam Altman have pivoted to warning that AI could kill you, which, with AI already polling badly, will make it much harder for AI to attract investment. x.comÂ
The market is lagging badly on CXL demand for Astera Labs and Marvell. The next two quarters for both companies will show just how demanding the industry has already become. x.comÂ
Astera Labs looks relatively expensive because similarly fast-growing AI infrastructure names trade at much lower multiples. Broadcom and Nvidia are at 14x, Credo at 15x and Lumentum at 18x; comparable peers look 50-80% cheaper. Astera is a great company and not necessarily expensive in absolute terms. Its roughly 2x multiple over Credo may persist, but the setup looks harder; with no valuation support, it could fall 50% if weakness continues. x.com x.com x.com x.comÂ
Marvell looks too expensive at 17x price to sales when peers in its space trade around 10x. @DGretta_Author argues its revenue relative to its market cap leaves the stock further to drop. x.comÂ
Marvell's valuation still reflects old cyclical models, overlooking an AI-driven structural shift that leaves room for a re-rating. Marvell focuses on AI networking and custom silicon, with data center above 70% of revenue and a lead in photonics interconnects, while long-term agreements secure demand and reduce cyclicality. Its EPS growth depends on execution. x.comÂ
Astera Labs may be a cleaner way to play the shortage in AI connectivity components than Marvell. Marvell's story is still a narrative whose earnings payoff is far off, leaving it vulnerable to sell-offs in between. The Google-Marvell arrangement that some see as a threat to Astera Labs is a 2028 issue, not an immediate one. x.com x.comÂ
