If you want chip exposure in one ticker, the decision comes down to two semiconductor ETFs: SMH or SOXX. Both are large, liquid, and own the same household names at the top.
The difference is how much of your money rides on the biggest stocks. That single design choice drives most of the performance gap.
Here is how to match the best semiconductor ETF to your investor profile.
SMH (VanEck): Top-Heavy Concentration in NVDA and TSM
The VanEck Semiconductor ETF (SMH) tracks the MVIS US Listed Semiconductor 25 Index. It holds around 25 names with market-cap weighting that lets the giants run.
As of February 2026, Nvidia and Taiwan Semiconductor combine for roughly 30% of the portfolio. Add Broadcom and the top three dominate the fund.
That concentration is a feature, not a bug. SMH gives you maximum exposure to the biggest winners in the chip cycle.
When NVDA rips on an AI capex update, SMH rips with it. When sentiment turns on the megacaps, SMH feels that too.
SOXX (iShares): More Diversified Across the Chain
The iShares Semiconductor ETF (SOXX) tracks the NYSE Semiconductor Index and holds about 30 names. The index caps any single stock at 8%, and constituents outside the top 5 are capped at 4%.
That rule changes the shape of the fund. TSM sits near 11% as the second-largest weight, with Broadcom and Micron above 7%.
You still get the megacap chip names. You just own less of them, and more of the equipment makers, memory players, and analog specialists behind the top of the cycle.
SOXX behaves like a broader read on the semiconductor industry rather than a leveraged bet on the largest two designers.
If you cannot decide between concentration and breadth, name the one stock you actually want to overweight. If you cannot, you probably want SOXX.
Verdict: Which Semiconductor ETF to Buy for Different Profiles
There is no single best semiconductor ETF for every investor. The right pick depends on how much single-stock risk you want and how you expect the cycle to play out.
You believe NVDA leadership continues
Pick SMH. The fund gives you the highest practical Nvidia weighting inside a diversified wrapper, plus heavy exposure to TSM as the foundry that actually prints those chips.
This is right if you think AI capex stays concentrated in a few hyperscalers and the data center buildout keeps favoring the current leaders.
You want broader chip cycle exposure
Pick SOXX. The 8% single-name cap forces a more balanced sleeve across design, manufacturing, equipment, and memory.
This fits investors who expect the rally to broaden into AMD, equipment names, and memory as orders work down the supply chain.
You already own NVDA directly
Pick SOXX. If Nvidia is already a top position in your stock book, SMH doubles down on that bet and inflates your effective concentration.
SOXX gives you sector exposure without stacking more NVDA risk on top.
You want a core long-term hold
Either works, but SOXX is the more conservative core. Its diversification rules reduce the chance that one stumble in one stock takes the fund down sharply in a session.
Expense Ratios, Liquidity, and Tracking Error
Fees are not the deciding factor. SMH charges 0.35% and SOXX charges 0.34%, so on a $10,000 position the cost difference is about one dollar a year.
Both funds are deeply liquid with tight bid-ask spreads, and tracking error for both is small relative to their stated benchmarks.
The real cost difference shows up in performance dispersion. When NVDA outperforms the rest of the basket by a wide margin, SMH leads. When the cycle broadens, SOXX catches up and sometimes pulls ahead.
SOXQ (Invesco) and XSD (SPDR): Equal-Weight Alternatives
If SOXX still feels too concentrated, two cheaper alternatives are worth a look.
SOXQ is the Invesco PHLX Semiconductor ETF. It tracks the same PHLX benchmark family that anchors SOXX but at a lower expense ratio, useful for buy-and-hold investors who want core chip exposure with minimal fee drag.
XSD is the SPDR S&P Semiconductor ETF and runs a modified equal-weight index. That tilt gives smaller chip names a bigger relative voice and pulls weight away from the megacaps that dominate SMH and SOXX.

Conclusion
SMH and SOXX own the same top names. They just disagree on how much of those names you should hold. SMH is the concentrated bet on the chip leaders, SOXX is the broader read on the cycle, and SOXQ and XSD lean further toward equal-weight exposure.
Open a Gotrade account to buy SMH, SOXX, or any of the alternatives in fractional shares, so you can size your semiconductor sleeve to match your conviction without committing to a full share at a time.
FAQ
Is SMH or SOXX better for long-term investors?
SOXX is the more conservative long-term core because its 8% single-name cap reduces the risk that one stock dominates returns.
How much do SMH and SOXX overlap?
The two ETFs share their largest holdings, including NVDA, TSM, and AVGO, but SMH weights them much more heavily than SOXX.
Are SOXQ and XSD better than SMH or SOXX?
They are cheaper and more equal-weight, which suits investors who want to dilute megacap concentration rather than ride it.
Why does SMH outperform when NVDA rallies?
NVDA is one of the largest weights in SMH, so a sharp NVDA move pulls the fund up more than it pulls SOXX, where the weighting is capped.
