Arm vs. NVIDIA: Which Semiconductor Stock Belongs in Your 10-Year Portfolio?

If you have a decade-long retirement horizon and one slot left for an AI semiconductor name, the choice between Arm Holdings (NASDAQ:ARM | ARM Price Prediction) and NVIDIA (NASDAQ:NVDA) is the question that matters right now. Both ride the same AI buildout. Both were just repriced violently after NVIDIA’s blockbuster May quarter. Only one belongs in a portfolio designed to fund withdrawals.

Arm has been the louder trade. The stock is up 271% year-to-date through June 1, including a 94% gain in May alone, as investors repriced its royalty model after NVIDIA’s print. NVIDIA, by contrast, has done nearly 20% year to date and more than 64% over the past year. The setup matters, because retirement capital cares more about what you pay than what just happened.

Dimension 1: On Valuation, NVIDIA Wins

This isn’t close. Arm trades at a trailing P/E of 475 and a forward P/E of 161, on a price-to-sales ratio of 89. NVIDIA trades at a trailing P/E of 34 and a forward P/E of 26, with a PEG ratio of 0.69. NVIDIA is the larger, faster-growing, more profitable business, and it trades at a fraction of Arm’s multiple. For a 10-year hold where the starting price determines a meaningful share of total return, that gap is the single most important number in this article.

Dimension 2: On Capital Return and Yield, NVIDIA Wins

Arm pays no dividend and runs no buyback. NVIDIA just raised its quarterly dividend to 25 cents from 1 cent, with an ex-dividend date of June 4, and payment on June 26. The board also authorized an additional $80 billion in buybacks in May, after returning roughly $20 billion in Q1 alone. The yield is still tiny, but the direction of travel is unambiguous: NVIDIA is now returning capital at scale. Retirement portfolios reward that signal. Arm’s cash is being plowed into R&D, with non-GAAP R&D up 43% year over year to $1.91 billion.

Dimension 3: On Volatility and Earnings Reliability, NVIDIA Wins.

Arm’s beta is 3.41 while NVIDIA’s is 2.24, making the former more volatile. Arm’s 52-week range runs from $100.02 to $421.69, a swing that should make any retiree uneasy. Arm also posted an EPS miss of roughly 49% in Q3 FY26, while NVIDIA delivered four consecutive quarterly beats, including Q1 FY27 revenue of $81.61 billion, up 85% year over year, with data center revenue of $75.25 billion (+92% YoY). Add in SoftBank’s controlling stake and active Qualcomm litigation, and Arm carries governance and legal overhangs NVIDIA doesn’t.

The Verdict

NVIDIA wins this matchup outright for a retirement-focused 10-year portfolio. You get the cheaper multiple, the dividend that just stepped up 25x, an $80 billion buyback behind the share count, a 63% net margin, and the most consistent earnings cadence in megacap tech. CEO Jensen Huang’s framing that the “buildout of AI factories is the largest infrastructure expansion in human history” is now backed by hard numbers.

Arm is the better stock only for one specific investor: the aggressive growth buyer who wants pure IP-licensing exposure to every AI chip shipped, including NVIDIA’s own Arm-based Vera CPU in the Rubin platform, and is willing to pay 31x price-to-sales versus NVIDIA’s 16x for 35% forecast EPS growth in fiscal 2027 against a $50 billion AI inference chip market in 2026. For the retirement portfolio that has to last 10 years and pay you along the way, NVIDIA is the position.
