MRVL surges 10% to enter S&P: Is it a bubble or AI infrastructure?

Monday, June 15, 2026

It jumped 10.43% in one trading day, closing at $308.88, just one step away from the all-time high of $324.20 set in early June—not a pulse for a small-cap monster, but an acceleration completed in the eyes of a $270.4 billion semiconductor giant.

What made it trending today wasn't some sudden earnings report, but a long-written ticket: Marvell will be officially included in the S&P 500 index before the market opens on June 22. Mechanical buying from passive funds poured in ahead of time, combined with NVIDIA CEO Jensen Huang calling it the "next trillion-dollar company" at COMPUTEX two weeks ago, with AI narratives and exponential effects resonating on the same day.

But problems followed

A well-known positive news with a written effective date can really continue to push the stock price higher on June 22. Or is it that smart money has long been lying in wait, waiting for that moment to cash out and exit?

From silicon wafers to light, it sells the "nerves and blood vessels" of AI servers

If Nvidia's GPUs are the brains of AI data centers, then what Marvell sells is more like the nerves and blood vessels connecting these brains. This is a fabless semiconductor company that does not build its own factories, focusing solely on designing data infrastructure chips, with products laid from the core of the data center all the way to the network edge.

Its specialty is a complete signal chain that others find hard to assemble: PAM and coherent DSP for high-speed optical communication, silicon photonics to reduce power consumption in optical modules, co-packaged optics (CPO) that packages optical devices and chips together to squeeze out extreme bandwidth, plus custom ASICs, CXL switches, and NVMe storage controllers.

The most recent quarter (ending May 2026) recorded $2.418 billion in revenue, a record high with a year-on-year increase of 28%; Full-year revenue for the previous fiscal year was $8.19 billion, a year-on-year increase of 42%. CEO Matt Murphy stated bluntly that the company is receiving "exceptionally strong AI orders" for custom XPUs, 1.6T optical interconnects, and 51.2T Ethernet switching chips.

So, why Marvell, and not someone else? The answer lies in its irreplaceability—from laser drivers and transimpedance amplifiers at the physical layer to Ethernet switch chips at the data link layer, only a handful of players like Broadcom can achieve such complete vertical coverage.

After doubling, what story can a 106x P/E ratio tell?

Let's start with a set of contrasts

A stock price of $308.88 corresponds to a price-to-earnings ratio as high as 106 times, while Broadcom, another AI semiconductor leader, has a P/E ratio of only 25 to 35 times. In other words, the market is paying Marvell a premium two to three times that of its mature peers.

Even more glaring is the technical side. The 50-day moving average is $183, and the 200-day moving average is only $108.52, while the current price is about 185% higher than the 200-day moving average. This means that over the past six months, the stock price has sprinted past the long-term moving average, and any pullback near the moving average would mean a halving potential.

Previously, when the stock price was $155, the reasonable value under three scenarios calculated using discounted cash flow (DCF) mostly fell between $40 and $115—but now the stock price has doubled to $308, and this valuation gap has not narrowed; in fact, it has widened.

Cash flow is the few comfort. Free cash flow surged to about $640 million in the most recent quarter, nearly doubling year-over-year, showing that the company is indeed self-sustaining. But compared to a market value of $270.4 billion, this amount of free cash flow yields less than 1%. If shareholders buy at the current price, the implied return is almost zero. So, is the market pricing today's cash flow, or is it paying for imagination three years from now?

The breakout phase has been validated, but who is still buying above the moving average?

According to the logic of the report, Marvell is in a "breakout" phase: revenue has grown positive quarter-on-quarter for several consecutive quarters, operating profit has turned from a loss in the previous fiscal year to a profit, free cash flow has entered a positive cycle, and the product line has fully taken shape from custom ASIC to CPO, marking the arrival of the commercialization harvest period.

This fundamental logic holds up. But the market's recognition of the "stage" ultimately depends on price—the 50-day moving average at 183 and the 200-day moving average at 108, with a huge vacuum between the two moving averages, indicating that this round of rally leaves almost no opportunity for those who exited midway to catch up.

The stage judgment is correct, but when everyone agrees "it's breaking out," the real risk often lies not in fundamentals, but in the question: who is still willing to take the baton at the high of 185% above the 200-day moving average?

The moat is intact, but the biggest rival stands right in front of it

Marvell's moat is a complete optoelectronic signal chain that others find hard to replicate in one go, combined with a 12 to 18-month chip certification cycle and two to three years of customer binding for custom ASIC projects—once it enters the list of qualified suppliers for hyperscale cloud providers, the replacement cost is so high that almost no one wants to touch it.

But no matter how deep the moat, it can't stop the higher mountain ahead: Broadcom (AVGO). Its AI semiconductor revenue has reached $10.8 billion, with a market value exceeding $500 billion. With its scale and vertical integration, it holds a leading position in custom ASICs and data center networks, and has a deeper history of custom collaboration with giants like Alphabet.

There were also two flanking attacks. Nvidia acquired Mellanox to acquire InfiniBand and NVLink, firmly locking the internal interconnection of GPU training clusters; Cisco, on the other hand, uses its self-developed Silicon One chip to directly compete with Marvell's Prestera series in direct procurement by hyperscale cloud providers.

So how should Marvell be positioned? It is more like the "second strongest" in AI network interconnection technology—clearly differentiated, but always looming over the cloud of Broadcom.

How big can a multi-billion-dollar cake be cut?

Looking at the bigger picture, the total market (TAM) for AI infrastructure semiconductors is estimated to be about $80 to $100 billion by 2025. If AI server shipments maintain an annual growth rate of over 30%, it could exceed $150 billion by 2027, with a compound annual growth rate of about 25% to 30%.

When it comes to the segments Marvell can truly serve—Ethernet switching and control, interconnected DSP, CXL switch, NVMe controllers, and CPO—conservatively estimated at about $15 to $25 billion, Broadcom's $10.8 billion in AI semiconductor revenue perfectly confirms that this is a century-long $10 billion cake.

But how large it can be cut is another matter. Considering Broadcom's dominance in custom ASICs and Nvidia's strength in GPU interconnect, Marvell's realistically available market share is estimated to be only 15% to 25% in its niche, and in the medium term, with CPO and CXL volume growth, it is expected to rise to $8 to $12 billion. The ceiling is high, but looking up is like someone else's heel.

The confidence of the bulls: accelerated revenue and a narrative endorsed by Jensen Huang

Supporting this round of rally is a set of mutually corroborating hard data and strong narratives—both indispensable:

Three factors determine the upcoming stock price rhythm

In the short term, Marvell's performance will be dominated by three types of events: whoever pays first will have the say in the next move:

• On June 22, the S&P 500 was officially included before the market opened: passive buying concentrated, but it also triggered the risk of "selling facts," with a neutral but uncertain direction
• Can GAAP earnings be realized for the full year 2026: Current GAAP quarterly net profit is only $34.5 million. To sustain a 100x P/E ratio, it will require orders of magnitude leaps in subsequent quarters, with a positive impact
• Order volume for 1.6T optical interconnect, 51.2T Ethernet, and custom XPU orders: Whether the CEO's so-called "exceptionally strong orders" can be converted into revenue is key to realizing the narrative, with a positive impact
• Oracle's $638 billion RPO delivery pace: If AI infrastructure investment slows, Marvell's demand visibility will be the first to be affected, with a positive impact
• CPO (Co-packaged Optics) Certified for Mass Production by Hyperscale Cloud Vendors: The Essential Fulcrum for Whether Mid-Term Valuation Can Hold Up Affects Neutrality

From SPAC to AI Boom: A Stock Repriced by Repeated Narratives

Looking at the long term, Marvell has been almost a "narrative-repeated price-fixed" model in recent years. After going public through a SPAC in 2020, it surged amid the digital boom; During the tech bear market from 2022 to 2023, the stock price was once again slashed to just over $30, with multiple rounds of layoffs to control costs.

The real turning point came after the AI narrative took over. Last fiscal year, revenue grew 42% year-over-year, with a single-quarter net profit peak of $1.9 billion, and the stock price started off from just over $50. Entering 2026, with the S&P 500 included in expectations and Huang's endorsement, it has risen about 57% more over the past month, surging to $308 today.

Looking back, both the expected revenue acceleration and AI demand were validated, except for the question of "whether the valuation is reasonable"—the stock price has far outpaced the improvement in fundamentals. History won't simply repeat itself, but the 200-day moving average at $108 reminds everyone just how low the starting point of this rally is.

⚠️ Risk Notice It is important to take a calm view: Marvell's current P/E ratio of 106x has already priced in extremely optimistic expectations. If subsequent quarterly earnings fall short of expectations, the tension between 100x valuations and weak GAAP profits could easily trigger a "Davis double kill"; Second, the current price is about 185% above the 200-day moving average and nearly 57% in one month, which itself inherently pulls the pull of mean reversion. Including the S&P 500, which is known as a positive factor, is more likely to trigger profit-taking; Furthermore, the concentration of income between China and Taiwan makes them unsafe in the face of geopolitical disturbances.

🟡 Neutral The positive news is real but has already been heavily priced in; the tension between 100x valuations and thin profits remains unresolved.

💬 Discussion On the day it was included in the S&P 500, would you choose to ambush or exit?
