Marvell falls 13.2% after reports it is in talks to acquire Lumentum

What happened

Marvell (MRVL) fell 13.2% on October 29, 2026, after reports it was in advanced talks to acquire Lumentum in an all-stock transaction that would dilute existing shareholders. The stock closed at $218.34, with after-hours quotes at $226.55 following the reports from Bloomberg and The Motley Fool. Trading volume was 2.0 times its 20-day average as investors weighed the takeover news and analysts referenced Marvell’s fiscal 2028 revenue guidance of about $20 billion in comparisons of valuation to expected fiscal 2028 earnings.

How big was the move

The decline was 2.9 times a typical daily move for this stock and 12.7 percentage points worse than the Technology sector median, while the S&P 500 that day fell 0.3%. The session came after the acquisition reports and was best described as a large, mostly company-specific move: the stock moved far more than the market and its sector, suggesting the company news was the likely driver. Volume at 2.0 times its 20-day average underlined the scale of the investor reaction. In the past five years the stock had 5 sessions with a decline of at least 13.2%; twenty trading days later the median result was a decline of 7.3%, and 2 of 5 were higher.

The technical picture

Technically the stock showed mixed signals. The stock was 13.3% below its 20-day moving average and 10.4% below its 50-day moving average, but 19.6% above its 200-day moving average, and it had spent 165 consecutive trading days above the 200-day average. The 50-day average is above the 200-day average, a sign of an established uptrend. The Relative Strength Index (14 days) stood at 40, a neutral reading between 30 and 70. The stock was 33.8% below its 52-week high. Shorter-term performance was uneven: the stock fell 17.4% over one month, rose 16.4% over three months and rose 146.8% over one year, the latter 134.8 percentage points ahead of the S&P 500. Volatility was 73% annualized over 60 days, higher than 83% of its own readings over five years, consistent with swings tied to deal speculation and AI-related momentum.
