Big tech companies, including Microsoft, Amazon, Alphabet, Meta Platforms, and Oracle, are committing hundreds of billions of dollars to capital expenditures in 2026. Most of it will go toward artificial intelligence (AI) infrastructure, with semiconductor chips a big part of that.
If you want a single ETF to capture that trend, the VanEck Semiconductor ETF (NASDAQ: SMH) is the one to own. Year to date (through June 16), the fund is up 71% after returning 49% in 2025. Over the past five years, it’s produced an average annual return of just over 38%.
Missed Nvidia in 2009? This Rare Signal Is Flashing Again. In 2009, a “Double Down” signal flashed for a little-known chipmaker called Nvidia. For the first time in years, that same “Total Conviction” signal is flashing for a company 1/100th the size of Nvidia. Continue »
How SMH constructs its portfolio
SMH tracks the MVIS U.S. Listed Semiconductor 25 index. It’s a simple market cap-weighted index of the 25 largest U.S.-listed semiconductor stocks. This means the portfolio tends to be somewhat top-heavy with the largest companies. Nvidia and Taiwan Semiconductor together account for nearly 25% of the portfolio. Add in the allocations to Micron, Advanced Micro Devices, and Intel, and you’ve got nearly half of it.
Company | Weight |
|---|---|
Nvidia | 14.5% |
Taiwan Semiconductor Manufacturing | 9.3% |
Micron Technology | 8% |
Advanced Micro Devices | 7.3% |
Intel | 7.2% |

As of this moment, however, that concentration delivers strong exposure to the sector’s leaders. Other ETFs, such as the iShares Semiconductor ETF (NASDAQ: SOXX), put caps on individual holding weights. It still has a large-cap tilt, but it’s a bit more diluted into smaller mid-cap names. It’s a modest difference, but one that can affect performance depending on what’s in favor at the moment.
SMH vs. competitors
The two main alternatives to the VanEck Semiconductor ETF are the iShares Semiconductor ETF and the Invesco PHLX Semiconductor ETF (NASDAQ: SOXQ).
When comparing, you could lump SOXX and SOXQ together because they’re essentially the same fund. Their selection criteria are very similar, with 74% overlap. The only major difference is the expense ratio. SOXQ’s expense ratio of 0.19% is nearly half that of SOXX, making it the winner on cost.
When comparing the VanEck ETF and the Invesco ETF, it really comes down to whether you want more concentrated megacap exposure in this sector. The VanEck one offers this, while the Invesco one gives greater weight to the smaller companies in this sector.
