Better Artificial Intelligence (AI) Stock: Marvell Technology vs. Broadcom

Broadcom is expected to grow AI revenue to $16 billion in the current quarter and exceed $100 billion in fiscal 2027, with analyst earnings growth projected at 71% this year and 62% next year. Marvell has also posted strong AI-related growth, but its shares have nearly tripled this year, making its valuation look richer and more volatile. The article argues Broadcom's cheaper valuation and stronger earnings outlook make it the better AI stock to buy right now.

Analysis

The key second-order dynamic is not simply that AVGO has stronger growth than MRVL, but that Broadcom’s customer concentration has shifted from a risk factor to a valuation catalyst. When a handful of hyperscalers are collectively locked into custom silicon roadmaps, the market starts capitalizing a longer duration of visibility and a higher probability of operating leverage; that is why AVGO can re-rate faster than the headline growth math alone suggests. MRVL’s recent multiple expansion, by contrast, makes it more vulnerable to even a single quarter of “good but not great” guide-and-tell execution.

For the supply chain, the real beneficiaries are adjacent networking, optics, and packaging vendors that get pulled along by AI data center spend even if custom ASIC share becomes a zero-sum battle. If AVGO’s AI run-rate really more than doubles over the next year, the bottleneck shifts away from silicon design and toward board-level integration, advanced substrates, and power delivery, which can create follow-on scarcity premiums in the ecosystem. That means the best expressions may not be outright longs in the two names everyone already owns, but in picks-and-shovels beneficiaries with less direct narrative saturation.

The contrarian miss in the market is that MRVL’s outperformance may already be discounting much of its upside while AVGO’s underperformance is partially a setup for estimate revisions to matter more than sentiment. The near-term risk to AVGO is not demand, but timeline risk: if any large customer ramps are back-end loaded, the stock can remain frustratingly dormant for another 1-2 quarters despite strong FY27 visibility. Conversely, MRVL’s risk is multiple compression if growth merely matches rather than beats the elevated expectation set by its recent move.

Key Decisions for Investors

• Initiate a 3-6 month long AVGO / short MRVL pair trade: AVGO’s valuation reset offers better upside capture if AI revenue revisions continue; stop if MRVL underperformance is driven by a discrete acceleration in orders rather than multiple expansion.
• Buy AVGO on any 5-8% post-earnings pullback over the next 1-2 quarters; target a 15-20% re-rating as the market begins to price FY27 AI revenue inflection, with downside limited by already-muted sentiment.
• Avoid chasing MRVL after its run; if long, finance it with out-of-the-money call spreads rather than cash equity, since the stock is more exposed to a 10-15% drawdown on any guide that fails to beat the elevated bar.
• Add an indirect AI infra basket long in packaging, optics, or power-delivery names as a second-order beneficiary trade; these should outperform if hyperscaler capex broadens beyond custom ASICs over the next 6-12 months.
• For event-driven exposure, use AVGO call spreads into earnings rather than outright stock to capture upside from guidance revisions while limiting the risk of a delayed-ramp/‘good-not-great’ reaction.
