Best Semiconductor ETFs

The first choice in chip ETFs is SMH versus SOXX, and it comes down to concentration versus breadth. Both draw from the same universe of US-listed semiconductor companies, so their holdings are largely the same names. The difference is how each one weights them. SMH, from VanEck, holds only around 25 names and weights mostly by market cap with little capping, so the largest names dominate: as of early 2026, NVIDIA sits near 20% and Taiwan Semiconductor near 10%, meaning the top two are roughly a third of the fund.

SOXX, from iShares, holds around 30 names and caps weights, so no single company runs away with the fund. NVIDIA lands closer to 9-10% rather than 20%, and the rest of the portfolio carries proportionally more. Both charge roughly 0.35% as of early 2026. The practical read: SMH is the concentrated, leaders-led option that rises and falls faster, while SOXX is the broader, more even option. If you want maximum exposure to the chip giants, SMH leans that way; if you want the same sector with the single-name risk dialed down, SOXX does.

XSD, the SPDR S&P Semiconductor ETF, takes a different shape: it is equal-weighted, so each holding gets a similar slice instead of weighting by size. That means NVIDIA, Broadcom, and a much smaller analog or equipment maker all count roughly the same. The effect is to reduce single-name risk and lean the fund toward mid-cap chip companies, which the cap-weighted funds barely register.

The trade-off cuts both ways. When the mega-cap leaders are doing the heavy lifting, as NVIDIA often has during the AI buildout, an equal-weight fund like XSD tends to lag SMH and SOXX because it deliberately holds less of the winners. When the rally broadens to smaller chip names, equal weighting can do better. XSD is the spread-out option for someone who wants chip exposure without leaning on the few largest companies.

SOXL, from Direxion, is not in the same category as SMH, SOXX, or XSD, and it is important not to treat it as a more aggressive version of them. SOXL is a 3x leveraged ETF that resets daily: it aims to deliver three times the daily return of a semiconductor index, for one day at a time. It is built as a short-term trading instrument, not a long-term holding, and it carries a higher fee (near 0.75% as of early 2026).

The reason it is risky to hold is volatility decay. Because the leverage resets every day, SOXL compounds daily moves rather than tracking the index over weeks or months. In a choppy, sideways market it can lose value even when the underlying index ends roughly flat, and over longer stretches its return can diverge sharply from three times the index. A sharp drawdown in the chips can wipe out a large portion of a leveraged position fast. SOXL is best understood as a trading tool used over short windows, not a buy-and-hold core, and it is far higher risk than the unleveraged funds above.

Chip ETFs swing more than the broad market for two compounding reasons: cyclicality and concentration. Semiconductors are a deeply cyclical industry, where demand booms and busts as inventory, capital spending, and end markets (phones, PCs, data centers, autos) move through their own cycles. As a result, chip ETFs commonly fall 30% or more peak to trough during a downturn, then recover sharply, a much wider range than an S&P 500 fund.

Concentration amplifies that. Funds like SMH lean heavily on a handful of names, so when NVIDIA, Taiwan Semiconductor, Broadcom, or AMD move, the fund moves with them. The upshot is that these funds behave like sector satellites, not core holdings, and position sizing is where the risk actually gets managed. Holding a smaller slice of a volatile, concentrated fund on top of a diversified base is a common way investors handle the swings; a large position concentrates the cyclicality.

SMH and SOXX are the two main, large, unleveraged options and differ mainly in concentration. XSD is the equal-weight alternative. FTXL and SMHX are smaller, screened or tilted variants worth naming. SOXL sits in a separate, much riskier category as a leveraged daily product. Figures are approximate and as of early 2026; confirm current details on each issuer's page.

The hard part of owning a chip ETF is not picking SMH over SOXX; it is sizing the position given how volatile and concentrated these funds are, and seeing how much they overlap with what you already hold. If you already own NVIDIA, Broadcom, or a broad tech or Nasdaq-100 fund, adding a chip ETF can stack a lot of weight on the same few names without you noticing. That is a question about your real portfolio, which a generic screener cannot answer.

That is where Walnut fits. It connects your existing brokerage through SnapTrade and lets you ask, in plain language through Claude, ChatGPT, or a built-in assistant, how much a chip ETF overlaps with what you already own and how a position has tracked against the S&P 500. It is read-only by default, and you approve any trade. Walnut is not an investment adviser; it helps you see and act on your own portfolio rather than telling you what to buy or how much to hold.

Semiconductor ETFs are a focused, cyclical way to hold the hardware behind the AI buildout, and the funds differ mainly in how they weight the same companies. SMH is the concentrated, leaders-led option with NVIDIA near 20%; SOXX is the broader, weight-capped option with NVIDIA closer to 9-10%; XSD is the equal-weight option that gives smaller names room. SOXL is a separate, much riskier 3x leveraged daily product, not a buy-and-hold core. Because these funds swing 30% or more in a cycle, they read as sector satellites, and position sizing matters more than the choice between SMH and SOXX.
