Marvell’s 31% Weekly Surge Conceals a 15% Friday Plunge as Analysts Cry Overvaluation
07.06.2026 - 01:07:56 | boerse-global.de
Marvell Technology’s breathtaking rally took a violent detour on Friday, when shares crashed more than 15% to €230.55, wiping out a chunk of the week’s extraordinary gains. Despite that single-day rout, the stock still finished the period up 31.29% — a testament to the ferocious momentum that has tripled the chipmaker’s value this year.
The catalyst for the euphoria was a double-barreled blast of good news. On Thursday, Jensen Huang, CEO of Nvidia, took the stage at COMPUTEX 2026 and anointed Marvell as the “next trillion-dollar company,” a blessing that sent traders scrambling. The rhetoric was backed by real money: Nvidia is investing $2 billion in a joint venture around NVLink Fusion, the interconnect technology that links AI accelerators in data centers. Then, after the bell on Friday, came the announcement that Marvell will join the S&P 500 on June 22, triggering forced buying by every index-tracking fund. The combination — a strategic endorsement from the king of AI and a passive-inflow catalyst — explains why the stock’s post-plunge after-hours trading remained steady.
Yet the Friday collapse underscores a glaring disconnect between narrative and price. At €230.55, Marvell trades roughly 158% above its 200-day moving average of €89.12 — a gap that technical analysts describe as unsustainable. The 50-day moving average sits at €142.09, a chasm that signals extreme overextension. The yearly high of €290.35, set on June 3, is already 20% in the rearview mirror, suggesting profit-takers are already active. With a 30-day annualized volatility of 119.5%, this is no longer a semiconductor stock; it is a leveraged bet on AI momentum.
Should investors sell immediately? Or is it worth buying Marvell Technology?
Analyst skepticism reinforces the technical warning. The consensus price target of €202.32 implies 12% downside from Friday’s close — and even that target is a reach, given the stock’s current altitude. The Relative Strength Index at 66.5, while not yet in overbought territory, has room to slide further. The psychological floor of €200 now looks critical; a breach would put the stock 30% above its 200-day average, still dangerously high.
None of this dismisses the fundamental story. Marvell’s data-center business now accounts for more than 75% of total revenue, up from less than 10% a decade ago. Its Teralynx T100 switch, capable of 102.4 terabits per second, positions it alongside Broadcom in the high-speed networking arena. Management raised its fiscal 2027 revenue forecast to $11.5 billion, representing 40% year-over-year growth, and expects custom-chip revenue alone to exceed $10 billion by fiscal 2029. These are not fantasy numbers — they reflect structural demand from AI infrastructure buildout.
But the question, as always, is price. The stock’s vertical trajectory has created a valuation that even friendly analysts find ambitious. The S&P 500 inclusion will provide a mechanical bid, but passive inflows cannot offset a fundamental re-rating if earnings fail to catch up. For long-term believers, Marvell remains a compelling AI-infrastructure play. For those expecting the momentum to continue without consolidation, Friday’s 15% rout offered a sobering reminder that gravity still applies.
