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.
Investment notice: ETF tickers and company names in this article are for illustrative purposes only. This is not a recommendation to buy, sell, or hold any security. Semiconductor ETFs are concentrated, high-volatility sector funds — all investing involves risk, including possible loss of principal. Past performance does not guarantee future results. Consult a qualified financial advisor before investing in sector-concentrated products.
Comparison methodology: ETFs are compared on publicly available expense ratio, assets under management, index methodology, and holdings data. Rankings by AUM reflect publicly reported figures. Inclusion in this comparison is not an endorsement or recommendation.
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) |

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)
Companies listed below are representative of typical semiconductor ETF holdings at the time of publication. Holdings change as indexes rebalance. These are not investment recommendations.
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.
