Simply Wall St has named three US AI stocks it says combine fast expected earnings growth with acceptable balance sheets: Marvell Technology, NVIDIA, and Advanced Micro Devices (AMD). Marvell, valued at $117.3 billion, makes data-centre chips and earns about $9.5 billion in revenue. Management guided optical interconnect growth at more than 50% year on year for fiscal 2027, against 20% or more for its ASIC segment. NVIDIA, worth $4,385.1 billion, earns about $275.4 billion from Compute & Networking and $27.6 billion from Graphics. Its growth case depends on staying dominant in GPUs and AI software, and rivals such as AMD, Intel, or a Chinese firm could challenge that. AMD has a market value of $663.3 billion and earns about $26.4 billion from Data Center products. It sizes its markets at about $2 trillion by 2030, but tight supply of advanced wafers and memory could limit growth.

Marvell Technology shares have fallen 49% in a month to $139.31, though they remain up 64% this year. The drop followed its November 2 all-stock deal to buy optical hardware maker Lumentum Holdings and a November 5 chip selloff after Democrats won control of Congress. Broadcom and AMD fell less, by 18% and 34%, suggesting deal-related selling on top of the sector move. Marvell's latest quarterly revenue rose 36.5% to $2.74 billion, and it expects the combined business to save more than $1 billion a year. Rosenblatt's Sajal Dogra kept a Buy rating with a $300 target. TD Cowen's Sean O'Loughlin cut his target to $175 from $350 and downgraded the stock to Hold, citing peak-cycle timing and possible earnings dilution.

Marvell Technology shares fell 37.0% between October 2 and November 2, 2026, while the S&P 500 lost 2.3%. Two of the biggest drops came with the Lumentum deal: 13.2% on October 29, when talks were reported, and 12.7% on November 2, when Marvell agreed to buy it in an all-stock deal valued at about $115 billion including debt. Business is still growing. Fiscal Q2 2027 revenue hit a record $2.739 billion, up 37% from a year earlier, and management guided Q3 revenue to $3.15 billion at the midpoint. Investors now pay less for each dollar of sales: 16.3 times at the November 2 close, down from 28.3 times at the end of June. Operating margin rose to 16.8% from 6.0%. Weak spots include communications revenue, which is expected to fall in Q3, and operating cash flow of $606 million, hit by supplier prepayments.
