Why is Marvell Technology stock sliding today?
Marvell Technology (MRVL) stock fell 5.2% in morning trading, reaching a low of $227.31 before recovering to $232.55. The decline is part of a broader selloff in AI semiconductor and optical communications stocks, driven by higher Fed rate-hike odds and cautious comments from Broadcom and TSMC executives. Investors are weighing Marvell's long-term AI growth prospects against its elevated valuation and recent insider selling.
