Best Semiconductor ETFs
Semiconductor ETFs are the picks-and-shovels play on AI. Here are the top options and how concentrated each one is.
Don't have time? Here's what you need to know:
- 1SMH (25 stocks, Nvidia ~20%) and SOXX (30 stocks, capped weights) are the top semiconductor ETFs
- 2Semiconductors are the picks-and-shovels play on AI — every AI system needs chips
- 3Expect 30-40% drawdowns — chip stocks are cyclical and volatile
- 4Keep semiconductor allocation under 10% as a satellite holding alongside your VTI core
Semiconductors: The Infrastructure Layer for Everything Digital
Every AI model, every smartphone, every data center, every electric vehicle runs on semiconductor chips. The global chip market exceeds $500 billion annually and is growing 10-15% per year. AI is the current growth driver — Nvidia's data center revenue grew from $15B to $47B in a single year on AI chip demand. Semiconductor ETFs give you concentrated exposure to this structural trend.
The sector is cyclical: chip demand surges during tech booms and drops during recessions as companies cut capital spending. SOXX fell 38% in 2022 before rallying 65% in 2023. If you own semiconductor ETFs, expect wider swings than the broad market.
Best Semiconductor ETFs Compared
SMH has the highest Nvidia concentration (~20%) — great when Nvidia is surging, risky if it stumbles. SOXX caps individual stock weights for more balance. XSD equal-weights every holding, giving smaller chip companies the same importance as Nvidia. Your choice depends on how much single-stock concentration you are comfortable with.
| ETF | Index | Expense Ratio | Holdings | Top Weight | Weighting Method |
|---|---|---|---|---|---|
| SMH | MVIS U.S. Semiconductor 25 | 0.35% | 25 | Nvidia ~20%, TSMC ~12% | Market-cap weighted |
| SOXX | ICE Semiconductor | 0.35% | 30 | Nvidia ~9%, Broadcom ~8% | Modified market-cap (capped) |
| XSD | S&P Semiconductor (equal weight) | 0.35% | 40 | Each stock ~2.5% | Equal-weighted |
| PSI | Dynamic Semiconductor | 0.56% | 30 | Quantitative model picks | Smart beta |
How Semiconductor ETFs Fit Your Portfolio
VTI already holds all semiconductor stocks at market weight. Nvidia is about 3% of VTI, with AMD, Broadcom, and others adding more. A semiconductor ETF doubles or triples your chip exposure. Keep it under 10% of your total portfolio — semiconductor stocks already make up roughly 8% of the S&P 500.
Semiconductor ETFs make more sense than broad AI ETFs because chips are the bottleneck — every AI company needs GPUs, but not every AI software company will succeed. It is the picks-and-shovels strategy: sell equipment to the gold miners rather than mining yourself.
Tip: If you want semiconductor exposure but less single-stock risk, SOXX's capped weighting prevents any stock from dominating the fund. SMH's uncapped approach gives you maximum Nvidia exposure — a concentrated bet within a concentrated sector.
Frequently Asked Questions
SMH or SOXX — which semiconductor ETF is better?
SMH has higher Nvidia concentration (~20% vs ~9%) and fewer holdings (25 vs 30). When Nvidia rallies, SMH wins. When Nvidia pulls back, SOXX falls less. Both charge 0.35%. Choose SMH for maximum AI/GPU exposure; SOXX for a more balanced semiconductor portfolio.
Are semiconductor ETFs too risky?
They are more volatile than the broad market — expect 30-40% drawdowns during downturns. But the long-term trend is strong: semiconductor demand grows with AI, cloud computing, EVs, and IoT. The risk is cyclical timing, not structural decline.
Should I buy a semiconductor ETF or just buy Nvidia stock?
An ETF is safer. Nvidia is a great company, but individual stocks carry single-company risk (management changes, product failures, regulation). SMH gives you Nvidia as the top holding plus 24 other chip companies as insurance. If Nvidia stumbles, the other holdings cushion the blow.
