SMH's 77% Rocket Ride on AI Spending Is Dazzling, But Can Semiconductor Stocks Keep This Pace Without a Pullback?

Shares of semiconductor companies have torn higher in 2026, lifting the VanEck Semiconductor ETF (SMH) — and by extension its Argentine-listed CEDEAR wrapper, SMHD.BA — by roughly 77% in just five months, dwarfing the S&P 500's 10.6% gain over the same stretch. For CEDEAR holders in Buenos Aires, the rally has been amplified further by local currency dynamics, making this one of the most profitable trades on the market. The question now: is the spending boom that fueled this surge durable, or are investors pricing in perfection? Semiconductor ETFs Surge 77% on a $700 Billion AI Spending Tsunami — But Can the Chip Boom Outrun Its Own Price Tag?

The VanEck Semiconductor ETF (SMH) — the U.S.-listed fund behind Argentina's SMHD.BA CEDEAR — has ripped 77% higher through the first five months of 2026, lapping the S&P 500's 10.6% return by a staggering margin. The fuel: an unprecedented wave of AI infrastructure spending that is rewriting the economics of the entire chip industry. For CEDEAR holders, the dollar-denominated gains layer on top of peso weakness, magnifying the windfall. But a 59x price-to-earnings ratio on the fund raises an uncomfortable question about what happens when the spending slows.

• Big Tech Is Writing the Largest Check in Corporate History. Microsoft, Alphabet, Meta, and Amazon have raised their combined 2026 capital-expenditure forecast to as much as $725 billion, most of it earmarked for AI infrastructure — data centers, chips, and networking gear.

These five companies alone plan to spend roughly $660–690 billion on infrastructure in 2026, the vast majority directed at AI compute. Every dollar of that spending flows directly into semiconductor orders, which is why SMH's rally is broad-based rather than a one-stock story.

• The Rally Is Wide but Top-Heavy. SMH's top holdings are NVIDIA at 15.9%, Taiwan Semiconductor at 9.6%, Micron at 8.2%, AMD at 7.4%, and Broadcom at 7.3%.

Notably, NVIDIA has risen only about 18% in 2026, while AMD has surged 114% — a sign that investors are rotating toward second-source chip suppliers that benefit as cloud giants diversify away from any single vendor. SMH's top 10 holdings still account for roughly 60–65% of the fund , meaning concentration risk remains real if any marquee name stumbles.

• The Revenue Is Real — For Now. Microsoft's AI business now runs at a $37 billion annual revenue pace, growing 123% year-over-year, while Alphabet's cloud revenue surged over 60%.

Gartner estimates global semiconductor revenue could jump 64% in 2026 to $1.32 trillion. Those are not speculative projections — they are orders already in the pipeline.

• Free Cash Flow Is the Hidden Risk. Pivotal Research projects Alphabet's free cash flow — the money left after all spending — will plummet almost 90% this year to just $8.2 billion.

All the hyperscalers report that their markets are supply-constrained, not demand-constrained , but if AI revenue growth disappoints even modestly, the spending spree could reverse fast — and semiconductor orders would be the first casualty. At nearly 60x earnings, SMH leaves zero room for error.
