Which Semiconductor ETF to Buy in May 2026
Choosing between SMH, SOXX, and SOXL is the first call any semiconductor ETF buyer faces in May 2026. AI capex, AMD’s Q1 print, and TSMC node demand have lifted all three, but they buy very different things.
One is a focused mega-cap basket. One is a broader index. One is a 3x daily trading tool.
Pick wrong and you either water down your AI exposure or wake up to compounding decay. Pick right and your semis sleeve does its job.
Index Differences: PHLX SOX vs MVIS US Listed Semi
SOXX tracks the NYSE Semiconductor Index (formerly PHLX SOX) with about 30 holdings and a 10% single-name cap. SMH tracks the MVIS US Listed Semiconductor 25 Index, holding around 25 names with heavier top-weighting.
The cap rule is the real difference. SOXX trims winners on rebalance. SMH lets NVDA run.
What SOXX is built for
SOXX favors breadth across design, foundry, and equipment names. Buy SOXX if you want exposure to the chip cycle without single-stock risk dictating your return.
What SMH is built for
SMH leans into the AI mega-caps that have led the tape. Buy SMH if you believe NVDA, TSM, and AVGO continue to compound from here.
NVDA, AMD, TSM Concentration in Each Fund
According to ETF.com, SMH’s top three (NVDA, TSM, AVGO) account for over 40% of assets, with NVDA alone near 20%. SOXX caps individual positions at 10%, so the same names sit at meaningfully lower weights.
That gap explains most of the recent return spread. When NVDA rips, SMH wins. When the cycle broadens, SOXX catches up.
Where AMD sits
AMD shows up in both funds but is not a top-three name in either. AMD exposure is roughly similar across SMH and SOXX, so AMD is not the swing factor.
The TSM angle
TSM is a top weight in SMH and a meaningful position in SOXX. If your thesis is leading-edge foundry, both vehicles deliver, but SMH gives you more of it per dollar.
SOXL targets 3x the daily return of the NYSE Semiconductor Index. That daily reset is the whole story. Hold it through a choppy week and compounding works against you, even when the index ends flat.
According to Direxion, SOXL should not be expected to deliver 3x the index over periods longer than one day. The fund is built for short-term tactical trades.
The decay math
If the index goes up 10% then down 9.09% (round trip to flat), SOXL goes up 30% then down 27.27%, ending down roughly 5.5%. The higher the volatility, the bigger the drag.
When SOXL works
SOXL pays off in a low-volatility uptrend with small daily gains stacking up. The day AMD printed +18% in Q1 2026, SOXL moved roughly 50%+. That is the trade SOXL exists for.

Total Return 1Y, 3Y, 5Y and Volatility Comparison
Across 1Y, 3Y, and 5Y windows, SMH has generally edged SOXX on total return thanks to NVDA’s outsized weight. Both have outpaced the S&P 500 over 5Y.
SOXL’s cumulative return depends entirely on the path. Trending bull tape, it leads. Choppy tape, it bleeds.
Volatility ranking
SMH sits slightly above SOXX on realized vol due to concentration. SOXL sits roughly 3x both, with reported volatility near 38%.
Expense ratio check
SMH and SOXX both run around 0.34 to 0.35%. SOXL costs about 0.99%, which is the price of the leverage wrapper, not a misprint.
Picking the Right Vehicle for Your Time Horizon
Buy SMH if your horizon is 3+ years and you want concentrated AI mega-cap exposure. Add SOXX if you want broader chip-cycle coverage with single-name risk capped.
Pair the two only if you want a tilt-plus-core structure inside one sector. Avoid SOXL for any holding period beyond a few days.
For long-term core
SMH or SOXX, sized to your overall tech weight. Do not double-count if you already hold QQQ or VGT, which already overweight the same semiconductor names in your existing portfolio core.
For tactical trades
SOXL with a stop, a defined holding window, and an exit plan. Treat it like an options trade with a clear thesis, not a passive position.
Conclusion
SMH is the buy for concentrated AI exposure. SOXX is the buy for broader, capped chip-cycle exposure. SOXL is a trader tool, not a core holding.
The right answer depends on your horizon and how you handle volatility. If you cannot stomach a 30% drawdown in one fund, do not put it in your core sleeve.
Open Gotrade, search SMH, SOXX, or SOXL, and place your trade with fractional shares so you can size to risk. Read more on expense ratio impact and our take on semiconductor stocks beyond NVDA before you buy.
FAQ
Is SMH or SOXX better in 2026?
SMH has led on returns thanks to NVDA weight, while SOXX offers broader exposure with a 10% single-name cap.
Can I hold SOXL long term?
No. Daily reset and volatility decay erode value over time, and Direxion explicitly warns against multi-day expectations.
What is the expense ratio of SOXL?
SOXL charges about 0.99% per year, well above SMH and SOXX which sit near 0.35%.
Should I pair SMH and SOXX?
Only if you want concentration plus breadth in one sector and accept the overlap in NVDA, TSM, and AVGO weights.
