Marvell Stock Forecast: MRVL Tests $168.81 Support as the $115 Billion Lumentum Deal Sparks a 13% Selloff

TradingKey - Marvell Technology (NASDAQ: MRVL) fell 12.72% to $171.41 on Monday, November 2, after agreeing to buy optical components maker Lumentum (NASDAQ: LITE) with its own shares, in a deal that values Lumentum at about $115 billion including debt, net of cash. Volume reached about 61 million shares, roughly three times normal, and premarket trading points to a small rebound at $175.50.

The stock has now fallen about 32% since October 28, the last close before reports of the talks, and sits 48% below its 52-week high of $329.88. BofA and TD Cowen both downgraded Marvell and cut their price targets by 44% and 50%.

The Deal Terms

Lumentum holders will receive 4.5 Marvell shares for each share they own, worth about $1,132 at October 28 prices, a 23.9% premium to Lumentum's price that day. Marvell holders will own about 67% of the combined company. The deal should close in the first half of 2028, after shareholder and regulatory approvals.

After Monday's drop, 4.5 Marvell shares are worth only about $771. Lumentum fell 18.59% to $684.40, about 11% below that value, a gap that reflects the long wait and the risk that the deal does not close.

Why Marvell Wants Optics

Marvell makes chips that move data as electrical signals inside AI data centers, while Lumentum makes the lasers and optical parts that move data as light. CEO Matt Murphy said, "AI infrastructure is undergoing a fundamental architectural shift toward optical connectivity," and the companies see a $550 billion market opportunity by 2030.

They expect more than $1 billion in annual cost savings and say the deal will add to non-GAAP EPS, which leaves out items such as stock-based pay, in the first year after closing. Marvell also said fiscal Q3 revenue is tracking in line with guidance.

Why the Stock Sold Off

BofA's Vivek Arya cut Marvell to Neutral from Buy and lowered his target to $225 from $400. He said $1 billion in cost cuts cannot offset a roughly 50% increase in the share count, adding, "There was no mention of any large M&A in MRVL's recent analyst day, so the news comes as a considerable surprise." He also flagged possible conflict with customers and a long regulatory review.

TD Cowen's Sean O'Loughlin cut Marvell to Hold from Buy, with a $175 target, down from $350. He expects mid-single-digit EPS dilution in 2028, meaning lower earnings per share as profits are spread over more shares, and warned the deal may come near the peak of the optical cycle. TD Cowen sees 2027 demand for optical transceivers, the modules that turn electrical signals into light, at $47 billion, against a consensus of about $100 billion, and if demand weakens into 2028, Lumentum's profits could fall faster than its sales.

Rosenblatt took the other side, keeping its Buy rating and $300 target, and Raymond James upgraded Lumentum to Strong Buy, calling the selloff overdone.

Even the in-line Q3 update did nothing to slow the selling. In my view, the problem is how Marvell is paying, with shares that have lost about a third of their value since the reports, for a business that may be near peak demand. At about 28 times forward earnings, the stock looks cheaper after the drop, but the deal clouds the outlook for 2028.

Marvell Technical Analysis: Weekly Close Below $168.04 Could Open $143.94

Marvell broke below its rising trendline in October. Monday's 12.72% drop took MRVL below the 50-week EMA at $182.07, with Friday's weekly close still ahead. EMAs are moving averages that give more weight to recent prices.

The stock is now testing $168.81, the 61.8% Fibonacci retracement of its big rally. Traders use this tool to measure how much of a move has been given back, and many treat the 61.8% level as the last major support before an uptrend is seen as broken. Monday's low of $168.52 dipped just under it before buyers stepped in.

RSI, a momentum gauge that runs from 0 to 100, has fallen to about 41, and the MACD, a trend-following momentum indicator, is dropping, so sellers are in control.

MRVL Price Chart - Source: Tradingview

A weekly close below $168.04 could send MRVL toward the 100-week EMA near $143.94, then $128.42. For buyers, reclaiming $199.33 would be the first sign of strength. The next resistance area runs from the 38.2% Fibonacci retracement at $229.84 to the horizontal level at $230.61.

I'm bearish while MRVL stays below $199.33, and a weekly close below $168.04 on Friday would confirm deeper losses.

FAQs

Why did Marvell stock fall?

Marvell fell 12.72% on Monday after agreeing to buy Lumentum in an all-stock deal worth about $115 billion, raising worries about a roughly 50% jump in its share count and buying near a possible peak in optical demand. BofA and TD Cowen both downgraded the stock.

The bias is bearish below $199.33 on the weekly chart. A weekly close below $168.04 could open $143.94 and $128.42, while reclaiming $199.33 would be the first sign of strength and could open $230.61.

Bottom Line

Marvell's case for optics is clear, but investors do not like it paying with a stock that has lost a third of its value in days. The key level is $168.81, the 61.8% retracement. I expect more pressure toward $143.94 if MRVL closes the week below $168.04, while a move back above $199.33 would show buyers are ready to look past the deal.
