Marvell Crashes 17% After Trillion-Dollar Hype Rally as $1 Trillion Chip Selloff Hits AI Sector

Marvell Technology (NASDAQ: MRVL) delivered one of the strongest AI growth stories in semiconductors this year. Then, in just one trading session, investors were reminded how quickly sentiment can reverse.

Shares plunged 16.7% on Friday to $263.47 after touching a record high of $316.43 a day earlier. The decline made Marvell the worst-performing major semiconductor stock during what became the industry’s sharpest selloff since the pandemic-era market crash.

The move came despite record revenue, raised guidance, growing partnerships with Nvidia and AMD, and Marvell’s upcoming inclusion in the S&P 500.

The selloff highlights a growing debate on Wall Street: how much future AI growth is already priced into semiconductor stocks.

Marvell’s AI Story Remains Intact

Fundamentally, Marvell continues to execute exceptionally well.

The company has transformed itself into one of the most important suppliers of AI infrastructure, specializing in custom AI chips, networking silicon, optical connectivity, and data-center interconnect technology.

Recent developments include:

• Record Q1 FY2027 revenue of $2.418 billion, up 28% year-over-year
• Q2 revenue guidance of $2.7 billion
• FY2027 revenue outlook raised to approximately $11.5 billion
• FY2028 revenue target increased to $16.5 billion
• Custom silicon business projected to exceed $10 billion by FY2029
• Data-center segment now represents more than 75% of revenue
• Nvidia recently expanded collaboration through NVLink Fusion initiatives
• AMD disclosed a strategic equity investment in Marvell

CEO Matt Murphy continues positioning Marvell as a leading supplier for hyperscalers building custom AI infrastructure.

The company benefits from the same long-term trends driving Nvidia, Broadcom, and Micron: exploding AI compute demand and growing investment in data-center connectivity.

Jensen Huang’s Endorsement Sparked a Historic Rally in Marvell Stock

Much of Marvell’s recent surge came after Nvidia CEO Jensen Huang publicly called the company “the next trillion-dollar company” during Computex in Taipei.

The endorsement triggered one of the biggest single-day gains in Marvell’s history.

Investors aggressively chased the stock higher.

Within days:

• Market capitalization surged above $275 billion
• Shares climbed more than 220% year-to-date
• Valuation expanded dramatically
• Expectations moved well ahead of near-term fundamentals

The problem wasn’t Marvell’s business.

The problem was the stock price began reflecting years of future growth almost immediately.

What Triggered the Semiconductor Selloff and Drove MRVL Stock Down?

The selloff was not specific to Marvell.

The entire AI semiconductor complex came under pressure.

Major declines included:

• Marvell: -16.7%
• Micron: -13%
• AMD: roughly -11%
• Intel: roughly -11%
• Nvidia: -6%
• Semiconductor ETF (SOXX): nearly -10%

Collectively, AI chip stocks erased close to $1 trillion in market value during the session.

Two major catalysts drove the decline:

1. Broadcom Failed to Raise AI Revenue Guidance

Broadcom reported strong earnings but maintained its existing AI revenue forecast instead of increasing it.

Investors interpreted that decision as a potential signal that AI spending growth may be normalizing.

Because Marvell trades heavily on AI expectations, the stock became particularly vulnerable.

2. Strong Jobs Data Hurt Growth Stocks

The latest U.S. employment report came in significantly above expectations.

Higher-than-expected job growth pushed Treasury yields higher and reduced expectations for near-term Federal Reserve rate cuts.

This matters because high-growth technology stocks derive much of their valuation from earnings expected years into the future.

When yields rise, those future earnings become less valuable in present-value terms.

The most richly valued stocks often fall hardest.

S&P 500 Inclusion Adds a New Catalyst for Marvell (MRVL)

Despite the selloff, Marvell received another major institutional endorsement.

The company will officially join the S&P 500 later this month after meeting profitability requirements.

The inclusion reflects how AI infrastructure companies are reshaping major market indices.

It also creates a structural demand catalyst because index funds and ETFs tracking the benchmark must purchase Marvell shares.

Historically, S&P 500 additions often attract increased institutional ownership and improve trading liquidity.

MRVL Technical Analysis: Long-Term Uptrend Remains Intact

Despite Friday’s sharp decline, Marvell’s broader technical structure remains bullish.

The stock continues trading above every major long-term moving average.

Key Technical Signals

The pullback occurred after a nearly vertical rally that pushed shares into overextended territory.

Even after the correction, Marvell remains dramatically above its long-term trend lines.

RSI and MACD

RSI: 65.02

• Momentum remains strong
• No longer at extreme levels
• Suggests some speculative excess has been removed

MACD: 33.51

• Remains positive
• Uptrend remains intact
• No confirmed long-term bearish reversal

Several shorter-term oscillators have rolled over from elevated levels, indicating momentum has cooled following the parabolic advance.

The setup increasingly resembles a healthy reset within a larger uptrend rather than a complete breakdown.

Key Support and Resistance Levels

Holding above the $240-$250 region would suggest institutional buyers remain active. A recovery above $300 could shift attention back toward Marvell’s recent highs.

Marvell’s Long-Term Outlook: One of AI’s Most Important Infrastructure Plays

Marvell occupies a unique position within the AI ecosystem.

Unlike Nvidia, which dominates AI compute, Marvell focuses on the networking, connectivity, optical interconnects, and custom silicon required to make large-scale AI clusters function efficiently.

The company’s long-term opportunity is supported by several trends:

• Hyperscalers increasingly adopting custom AI chips
• Rapid expansion of AI data centers
• Growth of high-speed optical networking
• Rising demand for AI inference infrastructure
• Increasing importance of data-center connectivity

The largest risk remains valuation.

Even after the selloff, Marvell still trades at a premium multiple relative to historical averages, leaving little room for execution mistakes.

However, if management achieves its FY2028 revenue target of $16.5 billion and delivers on its custom AI silicon ambitions, Marvell could remain one of the most influential beneficiaries of the AI infrastructure buildout.

For now, Friday’s decline appears less about deteriorating fundamentals and more about investors reassessing how much future AI growth should already be reflected in today’s stock price.
