Semiconductor ETFs offer concentrated exposure to one of the most important sectors in the global economy — but they come with elevated volatility and concentration risk. Here’s how the major funds compare.
Major Semiconductor ETFs Compared
| ETF | Ticker | Expense Ratio | Index Tracked | AUM (approx.) | # Holdings |
|---|---|---|---|---|---|
| iShares Semiconductor ETF | SOXX | 0.35% | ICE Semiconductor Index | ~$13B | ~30 |
| VanEck Semiconductor ETF | SMH | 0.35% | MVIS US Listed Semiconductor 25 | ~$20B | 25 |
| Invesco PHLX Semiconductor ETF | SOXQ | 0.19% | PHLX Semiconductor Sector | ~$1B | ~30 |
| SPDR S&P Semiconductor ETF | XSD | 0.35% | S&P Semiconductor Select Industry | ~$1B | ~40 (equal weight) |
AUM figures approximate; check fund provider websites for current data.
SOXX vs. SMH — Key Differences
Both SOXX and SMH are the dominant semiconductor ETFs, but their index methodologies create meaningful differences:
| Feature | SOXX (iShares) | SMH (VanEck) |
|---|---|---|
| Index | ICE Semiconductor Index | MVIS US Listed Semiconductor 25 |
| # of Holdings | ~30 | 25 |
| NVIDIA weighting | ~9–11% | ~20%+ |
| TSMC inclusion | Yes (as foreign listing) | Yes |
| ASML inclusion | Yes | Yes |
| Top concentration | More balanced | More NVIDIA-heavy |
| Rebalancing | Quarterly | Quarterly |
SMH has historically had a higher NVIDIA weighting, which boosted performance significantly in 2023–2024 when NVIDIA surged. This cuts both ways — higher concentration means more volatility.
Top Holdings (Representative 2026)
Typical top holdings across major semiconductor ETFs:
| Company | Role in Sector |
|---|---|
| NVIDIA (NVDA) | GPUs, AI accelerators, data center chips |
| TSMC (TSM) | World’s largest chip foundry |
| Broadcom (AVGO) | Networking chips, custom AI accelerators |
| ASML (ASML) | EUV lithography equipment (near-monopoly) |
| Qualcomm (QCOM) | Mobile chips, 5G modems |
| Intel (INTC) | x86 processors, foundry ambitions |
| Applied Materials (AMAT) | Chip manufacturing equipment |
| Lam Research (LRCX) | Etching and deposition equipment |
| KLA Corp (KLAC) | Process control equipment |
| AMD (AMD) | CPUs, data center GPUs |
Performance and Volatility
Semiconductors are among the most volatile equity sectors:
- 2023: SOXX +68%; SMH +74% — AI-driven demand surge
- 2022: SOXX −45%; SMH −44% — rate hikes, oversupply concerns
- 2020: SOXX +52% — pandemic digital demand acceleration
Investors should expect 40–50% drawdowns in bear markets. The long-term bull case (AI, data centers, electrification, IoT) is compelling — but the journey is volatile.
XSD — The Equal-Weight Alternative
The SPDR S&P Semiconductor ETF (XSD) uses an equal-weight methodology rather than market-cap weighting. This means:
- Less NVIDIA/TSMC concentration
- More exposure to mid-cap chip companies
- Higher small-cap and emerging company exposure
- Different risk/return profile — can underperform or outperform SOXX/SMH depending on which companies lead
XSD is useful for investors who believe concentrated NVIDIA exposure is excessive.
Key Risks
US-China trade tension: Export controls on advanced chips and chip equipment (ASML, Applied Materials, Lam Research) are a persistent risk. Escalation could significantly impact fund holdings.
TSMC/Taiwan geopolitical risk: TSMC manufactures the most advanced chips in the world — almost all of them in Taiwan. Geopolitical tension in the Taiwan Strait is a systemic risk for the entire sector.
Cyclicality: Chip demand cycles through boom and bust periods driven by PC refresh cycles, smartphone penetration, data center capex, and automotive demand.
Customer concentration: NVIDIA’s dependence on a handful of hyperscaler customers creates revenue concentration risk.
Should You Buy a Semiconductor ETF?
Appropriate if:
- You want concentrated sector exposure as a satellite position (5–15% of portfolio)
- You have a long time horizon (10+ years) and can tolerate 40%+ drawdowns
- You believe AI, data centers, and electrification will drive sustained chip demand
Not appropriate if:
- This would be a core or sole holding
- You need the money within 3–5 years
- You can’t stomach major volatility
Consider that the S&P 500 (through a broad index fund) already has approximately 8–12% exposure to semiconductor companies. A dedicated semiconductor ETF adds concentration on top of existing broad market exposure.
Semiconductor ETFs are closely related to AI ETFs — both capture different layers of the AI supply chain.
