Marvell Technology fell 7.73% to $201.46 after Bloomberg reported the company is in advanced talks to acquire optical and photonic components maker Lumentum Holdings, valued at roughly $83 billion—nearly 38% of Marvell's own $221 billion market cap. Investor concern centers on financing risk and potential share dilution given Marvell's modest cash reserves, triggering classic "sell the acquirer" sentiment. The decline follows a 13.2% plunge in the prior session.
Marvell Technology fell 12.57% to $220.02 intraday on October 29, 2026, driven by reported acquisition talks with Lumentum Holdings and a broader tech sell-off following Alphabet's earnings miss (per 247wallst.com and Yahoo Finance). The potential $83 billion Lumentum deal—roughly 38% of Marvell's ~$221 billion market cap—has triggered concerns over dilution, given Marvell's limited cash position of ~$3.92 billion and likely need for heavy debt or equity financing.
Marvell Technology fell 8.55% to $223.84 as part of a broader semiconductor and AI-infrastructure sector sell-off on October 22, 2026 (per web sources including investing.com and CNBC). The decline reflects weak sentiment across the chip complex—compounded by cautious guidance from peers like Lam Research—combined with macro headwinds including a Nasdaq selloff, rising oil prices, and geopolitical concerns driving a flight to safety. Volume stood at 1.27x normal for this point in the trading session.

Marvell Technology fell 5.14% to $228.85 as semiconductor stocks retreated broadly on October 16, 2026, amid sector-wide pressure from higher inflation data raising Federal Reserve rate-hike odds, concerns over AI capital constraints from industry leaders, and persistent insider selling exceeding $52.5 million over the past 12 months with no offsetting insider buys, per web synthesis. Peers including Micron and NVIDIA also declined; Technology Equipment sector fell 1.54%.
Marvell Technology fell 5.37% to $232.10 as AI stocks tumbled amid a hot inflation reading and Anthropic's slowing revenue growth, extending a broader tech selloff (Barron's).

Marvell Technology rose 4.13% to $282.44, building on a 31% monthly surge driven by strong AI and data center demand (Yahoo Finance). Volume reached 32.2M shares, 4.55x the time-adjusted average, signaling broad participation in the rally.
Marvell Technology rose 6.11% to $259.17, likely driven by the company's announcement of industry-first 2nm optical interconnect technology demonstrations for AI data center infrastructure at ECOC 2026 (Business Wire, Sept. 20).
