Semiconductor Stocks Gain 18% YTD as AI Demand Accelerates

The semiconductor sector, as tracked by the VanEck Semiconductor ETF (SMH), has advanced 18% year-to-date through May 26, 2026, according to a market analysis. This performance significantly outpaces the S&P 500’s 8% gain over the same period. The sustained rally is fueled by unprecedented demand for high-performance chips required for artificial intelligence training and inferencing. The sector’s momentum highlights its critical role in the ongoing digital transformation across global industries.

Context — [why semiconductor stocks are surging now]

Demand for AI-optimized chips has become the primary catalyst for the sector's outperformance. The last major surge in semiconductor valuations occurred in 2024, when the SMH ETF gained over 65% for the year, driven by the initial commercial deployment of generative AI models. Current macroeconomic conditions, including stable interest rates, have provided a favorable backdrop for growth-oriented technology investments. The recent acceleration stems from concrete capital expenditure announcements from major cloud providers like Amazon Web Services and Microsoft Azure, which have committed billions to expanding AI-dedicated data center capacity. These hyperscalers are the primary customers for the most advanced graphics processing units and custom silicon.

Supply chain normalization has also been a key factor. The acute shortages that plagued the automotive and consumer electronics industries from 2021 to 2023 have largely abated. This has allowed chip manufacturers to focus on fulfilling high-margin orders for AI and high-performance computing clients without significant production bottlenecks. Geopolitical tensions continue to influence manufacturing and export strategies, with companies diversifying production outside of single regions to mitigate risk. The current cycle is characterized by a bifurcation in demand, with strength in AI and automotive chips offsetting relative softness in certain segments of the consumer PC and smartphone markets.

Data — [what the numbers show]

The scale of the sector's move is evident in both broad indices and individual stock performances. The VanEck Semiconductor ETF (SMH) holds a market capitalization exceeding $25 billion and trades at an average price-to-earnings ratio of 28.5. Leading constituent Nvidia, which commands an estimated 80% share of the data center AI chip market, has seen its stock price increase over 40% year-to-date. Taiwan Semiconductor Manufacturing Company (TSM), the world’s largest contract chipmaker, reported quarterly revenue of $18.5 billion, a 16% year-over-year increase driven by strong 3-nanometer and 5-nanometer process technology demand.

For comparison, the broader technology sector, represented by the Technology Select Sector SPDR Fund (XLK), has gained 12% YTD. The performance disparity between semiconductor-specific stocks and the wider tech index underscores the unique tailwinds for chipmakers. Advanced Micro Devices (AMD) has gained 22% this year, while memory chip specialist Micron Technology is up 30% on rebounding DRAM pricing. The Philadelphia Semiconductor Index (SOX) has similarly outperformed, rising 20% since the start of the year. Capital expenditure forecasts from the top five foundry companies indicate a collective investment of over $200 billion in new capacity through 2027.

Company	YTD Performance	Primary Catalyst
Nvidia (NVDA)	+40%	AI GPU Demand
Broadcom (AVGO)	+15%	Custom AI Chip & Networking
AMD (AMD)	+22%	MI300X AI Accelerator Adoption
TSMC (TSM)	+18%	Leading-Edge Manufacturing Capacity

Analysis — [what the rally means for investors]

The concentration of gains in AI-centric companies like Nvidia and AMD creates a narrow leadership dynamic within the sector. While this drives index-level performance, it also introduces vulnerability should AI-related capital expenditure slow. Secondary beneficiaries include semiconductor capital equipment firms like Applied Materials and ASML, which supply the complex machinery needed to manufacture advanced chips. These companies typically experience order growth several quarters after foundries commit to expansion plans. The automotive semiconductor segment remains a steady growth area, with electric vehicle production and advanced driver-assistance systems requiring increasing chip content per vehicle.

A key risk to the current valuation thesis is customer concentration. A small number of hyperscale cloud companies account for a disproportionate share of revenue for leading AI chip designers. Any moderation in their spending would have an immediate and significant impact on supplier earnings. Institutional positioning data from futures and options markets shows that leveraged funds have built substantial long positions in semiconductor indices, indicating crowded bullish sentiment. This high conviction trade could lead to amplified volatility if sentiment shifts. The memory market recovery provides a more diversified demand driver, as DRAM and NAND flash are used across all electronic devices, from smartphones to servers.

Outlook — [what to watch next in semiconductors]

The immediate catalyst for the sector is the next round of quarterly earnings reports, beginning with Micron Technology on June 25. Investors will scrutinize guidance for Q3 2026 for signs of sustained demand, particularly for high-bandwidth memory used in AI servers. The next major industry event, Taiwan’s Computex conference in early June, will feature keynotes from AMD, Qualcomm, and Intel, often revealing new product roadmaps and partnership announcements. Market participants will monitor commentary on the adoption timeline for the next-generation PCIe 6.0 standard and GDDR7 memory, which will define the next performance leap for AI accelerators.

From a technical analysis perspective, the SOX index is testing a key resistance level around the 5,200 mark, a zone that previously acted as support in late 2025. A sustained break above this level on high volume would signal continued institutional accumulation. Critical support rests at the 4,800 level, which aligns with the 100-day moving average. Geopolitical developments remain a persistent watch item, particularly any changes to export control policies affecting trade with China or tensions in the Taiwan Strait, which could disrupt the global supply chain for advanced logic chips. The U.S. presidential election in November may also bring policy shifts regarding semiconductor subsidies and trade.

Frequently Asked Questions

What is the best way to invest in semiconductors?

Investors typically gain exposure through diversified instruments like the VanEck Semiconductor ETF (SMH) or the iShares Semiconductor ETF (SOXX), which hold baskets of leading companies across the chip supply chain. This approach mitigates single-stock risk associated with individual manufacturers or designers. For direct stock exposure, the market is segmented into fabless designers (Nvidia, AMD), integrated device manufacturers (Intel), and pure-play foundries (TSMC). Each segment carries different risk profiles tied to capital expenditure cycles, intellectual property, and geopolitical factors.
