Marvell Tech down 34% from peak, but analysts favor Broadcom instead

Marvell Technology has experienced significant volatility in recent months, with its stock price falling approximately 34% from its all-time high. Despite this sharp decline, the stock's current price remains above where it closed at the end of May, indicating that the recent sell-off, while substantial, has not entirely erased earlier gains in the year.

The company operates two primary business units that drive investor interest. The first is networking equipment that manages data flow within data centers — a critical function in large-scale computing infrastructure. The second is custom AI chips, which Marvell designs specifically to match the computational workloads of its clients. This business model mirrors that of competitor Broadcom, which also offers networking equipment and custom silicon alongside other products, making Broadcom a natural comparison point for evaluating Marvell's investment merit.

Marvell's custom AI chip customers include two major cloud-computing players: Microsoft and Amazon. Broadcom, by contrast, counts Alphabet, Meta Platforms, OpenAI, and Anthropic as clients. Critically, Broadcom's customer base has been more aggressive in ordering custom AI chips, which has translated into stronger financial performance and analyst projections. Wall Street expects Marvell to achieve 41% revenue growth in the current fiscal year and 45% growth in the following year, with next year's total revenue projected to reach $16.7 billion（約2.7兆円）. Broadcom, in comparison, is expected to grow 66% this year and 63% next year, with revenue reaching $172 billion（約28兆円） — demonstrating a substantial size and growth-rate advantage.

What makes this comparison particularly relevant to the investment question is valuation. Despite Broadcom's superior growth expectations and larger revenue base, it trades at a significantly lower valuation multiple than Marvell. This dynamic suggests that for investors seeking exposure to the custom AI chip market, Broadcom offers better value on multiple dimensions: a larger and more aggressive customer base, stronger analyst expectations, and a lower stock price. While Marvell remains a fundamentally sound company with reputable clients, the comparison indicates that Broadcom presents a more compelling investment opportunity for those evaluating AI semiconductor plays.

Marvell Technology's 34% decline from its peak has created a moment for investors to reassess their AI semiconductor positions. The stock's slide, though notable, does not fully erase gains from May's close, suggesting the sell-off is selective rather than catastrophic. The real question for investors lies not in Marvell's intrinsic health — it remains a solid operator with marquee customers in Microsoft and Amazon — but in relative value within a peer set.

The comparison with Broadcom is instructive because the two companies are structurally similar: both derive revenue from data-center networking and custom silicon. Yet the execution and client dynamics diverge sharply. Broadcom's customer base — anchored by Alphabet, Meta, OpenAI, and Anthropic — has shown more aggressive demand for custom AI chips, translating into analyst projections of 66% revenue growth this year and 63% next year, with revenue reaching $172 billion（約28兆円）. Marvell, by contrast, faces analyst expectations of 41% and 45% growth in the same periods, with next-year revenue of $16.7 billion（約2.7兆円）. The valuation gap compounds this gap: despite Broadcom's superior growth trajectory, it trades at a materially lower valuation multiple. For investors weighing the two, Broadcom's combination of larger scale, higher growth, broader customer reach, and cheaper price makes it the more compelling choice.
