Stock Market Today, Nov. 3: Marvell Shares Edge Higher After Premarket Drop on $115 Billion Lumentum Deal

On November 3, Marvell Technology's stock exhibited a rebound following a premarket decline triggered by the company's announcement of a $115 billion acquisition of Lumentum. The semiconductor provider's shares closed at $171.97, up 0.33%, after being volatile due to the deal and several analyst downgrades. Trading volume surged to 37.6 million shares, approximately 67% higher than its three-month average of 22.6 million shares.

Marvell, an IPO from 2000, has experienced an impressive 1,114% growth since going public. The S&P 500 and Nasdaq Composite also showed gains, with the S&P 500 rising 0.36% to 7,569 and the Nasdaq Composite gaining 0.83% to 25,372.

Other peers in the semiconductor equipment and integrated circuits for data center and networking infrastructure sectors, such as Broadcom and Arista Networks, also experienced price increases. Broadcom closed at $332.13, up 3.07%, while Arista Networks finished at $169.91, up 3.52%. These gains are attributed to the growing significance of AI-infrastructure spending.

On Tuesday, Marvell's stock rose the day after a 13% plunge following the $115 billion all-stock acquisition of Lumentum. This growth in share price indicates that Wall Street may have viewed the stock as oversold. Marvell's decision to acquire Lumentum is expected to significantly boost revenue growth. Prior to the deal, Marvell had already raised its revenue outlook for the 2028 fiscal year, ending on January 31, 2028, to $20 billion, and set a range of $70 billion to $90 billion for fiscal year 2031 sales.

Lumentum's strong performance in Q1 of fiscal year 2028, with a 137% year-over-year sales increase to $1.3 billion, further justifies Wall Street's reassessment of the acquisition.
