Semiconductor ETFs: SMH, SOXX, or SOXQ - Which One to Buy? (2026)

The world of exchange-traded funds (ETFs) is an intriguing arena, especially when it comes to the semiconductor sector. With big tech giants like Microsoft, Amazon, and Alphabet committing to massive capital expenditures, the demand for semiconductors is set to soar. This presents an exciting investment opportunity, but which ETF should you choose to capitalize on this trend? Let's dive into the battle of SMH, SOXX, and SOXQ.

The Contenders

We have three ETFs vying for attention in the semiconductor space: the VanEck Semiconductor ETF (SMH), the iShares Semiconductor ETF (SOXX), and the Invesco PHLX Semiconductor ETF (SOXQ). While they share many similarities, there are some key differences that set them apart.

VanEck Semiconductor ETF (SMH)

SMH is the most concentrated of the three, with a heavy focus on AI infrastructure. Its top holdings include Nvidia and Taiwan Semiconductor Manufacturing, which account for a significant portion of the portfolio. This fund has delivered impressive returns, with an average annual growth of 36% over the last five years. However, its concentration also means it's more susceptible to the performance of these mega-cap stocks.

iShares Semiconductor ETF (SOXX)

SOXX takes a more balanced approach by capping individual stock holdings. This creates a portfolio with a slightly higher tilt towards smaller companies. Its top holdings include Micron and Advanced Micro Devices. While SOXX offers a more diversified play, its expense ratio of 0.34% is a consideration, especially when compared to its competitors.

Invesco PHLX Semiconductor ETF (SOXQ)

SOXQ is the cheapest option, with an expense ratio of just 0.19%. It tracks a similar index to SOXX but with a lower cost. Its top holdings mirror those of SOXX, with Micron and Nvidia taking the lead. The lower expense ratio has historically resulted in modest outperformance over SOXX, making it an attractive option for investors.

The Battle

When comparing SMH, SOXX, and SOXQ, it's clear that they are all vying for a piece of the semiconductor pie. SMH's concentration and impressive returns make it an attractive choice for those looking to overweight specific stocks. SOXX offers a more balanced approach, but its cost may be a deterrent. SOXQ, with its lower expense ratio, provides a cost-effective option that has historically outperformed SOXX.

My Take

Personally, I believe the Invesco PHLX Semiconductor ETF (SOXQ) is the winner in this battle. While all three ETFs are likely to perform similarly, the lower cost of SOXQ makes it a more appealing choice. The modest outperformance over SOXX, coupled with its diversified portfolio, makes it a solid satellite holding. However, it's important to remember that these ETFs should be considered as part of a well-rounded investment strategy, and position sizing should be limited.

The anticipated growth in capex spending and revenue over the next few years makes the semiconductor sector an exciting prospect. With the right ETF, investors can capitalize on this trend while managing their risk effectively. So, if you're looking to invest in the semiconductor space, SOXQ might just be the fund to consider.
