Marvell's 44% Plunge Meets a $400 Bull Case: The AI Chipmaker's Reckoning

Marvell shares tumble 44% amid AI-chip selloff, but Amazon deal and record Q1 revenue hint at upside with consensus target at €223.89.

The numbers tell a story of whiplash. Marvell Technology shares closed Friday at €162.72, up 2.42% on the day, yet that modest bounce does little to mask the carnage of recent weeks. The stock has shed nearly 44% from its 52-week high, with roughly 32% of that damage concentrated in the past 30 days alone. For investors who have held through the turbulence, the consolation prize is a year-to-date gain that still exceeds 123%.

A Sector-Wide Selloff, Not a Company-Specific Crisis

The catalyst for the slide wasn't a Marvell-specific disappointment. Rather, a broad rotation out of the so-called "AI-memory trade" swept through high-growth chip names indiscriminately, hitting memory manufacturers and custom-silicon providers alike. On one particularly brutal trading day, Marvell lost around 8% even as the broader market advanced and advancers outnumbered decliners on the tape.

That undifferentiated selling punished a datacenter supplier for weakness in memory chips — a distortion that has pried open the gap between price and fundamentals. The parabolic run into June only compounded the problem. The stock hit an all-time high of €290.35 in early June, fueled by expectations of AI datacenter demand. The current price sits almost 44% below that peak, a stark illustration of how quickly euphoria can curdle into caution when valuations run too hot.

The Amazon Deal That Shifted the Narrative

For months, the overhang on Marvell's valuation was the fear of losing Amazon as a customer. That concern now appears to be dissipating. The semiconductor company has inked a five-year agreement with Amazon, a deal designed to put doubts about the relationship to rest. KeyBanc responded by raising its price target to $400, citing the ramp of Amazon's Trainium-3 chip and a win with Alphabet as another customer. That puts the firm among the most bullish voices on the custom-AI-chip maker.

Not everyone shares that enthusiasm. Erste Group downgraded the stock to Hold on July 15, striking a notably more cautious tone than the broader consensus. The range of price targets across the Street reportedly spans from roughly $90 to $400 — a reflection of genuine uncertainty about how durable the growth in custom AI chips will prove to be. The consensus target sits at €223.89, implying upside of about 37.6% from Friday's close.

Fundamentals Hold Up, Even as the Chart Suggests Otherwise

The operational picture remains solid. For the first quarter of fiscal 2026, which ended May 27, Marvell posted record revenue of $2.42 billion, up 28% year over year. Earnings per share came in at $0.80, with the datacenter segment contributing 76% of total revenue. The company guided to $2.7 billion in revenue for the current quarter — a 35% increase over the prior-year period — with EPS expected at $0.93. Management, led by CEO Matt Murphy, is targeting $10 billion in annual revenue from the custom-AI-chip business by fiscal 2029. The next earnings report is expected in late August.

Management also anticipates growth accelerating through fiscal 2027. Investors will get more clues in the coming weeks as major cloud providers report their capital expenditure figures — numbers that will serve as the real test of Marvell's guidance.

The Technical Picture: Correction Within an Uptrend

From a chart perspective, the stock is trading almost exactly at its 100-day moving average of €164.12. Meanwhile, it remains 37.58% above its 200-day average of €118.27. That combination — capitulation toward the medium-term trendline while maintaining a healthy distance from the longer-term base — fits the profile of a sharp correction within an intact uptrend rather than a structural breakdown. The relative strength index at 40.8 supports that reading: soft enough to reflect the recent beating, but far from the oversold extremes that would signal a genuine trend reversal.

A Valuation That Demands Conviction

The ambition in the multiple is hard to ignore. The forward price-to-earnings ratio stands at roughly 57, with a price-to-sales ratio around 17. Skeptics point out that Marvell's share of the custom ASIC market has slipped from 12% to 8%, and that net income has declined significantly year over year. A contingent liability of approximately $332 million and $2 billion in convertible debt are balance-sheet items investors would be wise to monitor.

Institutional Divergence and Insider Selling

The big-money picture is decidedly mixed. Norges Bank built a new position worth $895 million in the first quarter, while several fund managers significantly increased their holdings. On the other side, Bank of America trimmed its stake by nearly 14%, selling roughly 1.6 million shares. Insiders have been predominantly sellers over the past three months, offloading shares worth $8.2 million with no purchases to offset the selling. Institutions hold just over 83% of Marvell's shares — a concentration that likely amplified the recent volatility.

The Risk That Remains

None of this makes the stock safe. With an annualized 30-day volatility of roughly 92%, double-digit swings in either direction are the norm, not the exception, as long as anxiety about AI investment persists. Marvell's own history demonstrates that momentum names can fall longer than fundamentals would justify if broader fears about AI spending cuts take hold. The upcoming earnings date — not yet officially announced — adds another layer of event risk that could reignite volatility in either direction.

For now, the bull case rests on a simple proposition: the selloff was driven more by a sector-wide repricing of AI multiples than by deterioration in Marvell's own order book. The current level, in that view, is less a verdict on the growth story than a stress test of conviction. Whether that conviction holds will depend on the hyperscaler capex numbers in the weeks ahead — and on whether the Amazon deal proves to be the anchor that finally stabilizes the narrative.
