SOXQ vs SOXX

Key Takeaways

• Both SOXQ and SOXX are passively managed semiconductor ETFs with near-identical correlation, but they track slightly different underlying indexes.
• SOXX is the far larger and more liquid fund, holding roughly $45 billion in assets versus about $3 billion for SOXQ.
• SOXQ is meaningfully cheaper, with a 0.19% expense ratio compared with about 0.35% for SOXX.
• Both funds have been pressured in recent weeks by questions over AI infrastructure spending and rising borrowing costs, yet remain strongly positive year to date.
• Top-holding composition differs slightly: SOXQ skews toward NVIDIA, Broadcom, and Micron, while SOXX leads with AMD, Intel, and NVIDIA.

Introduction

Semiconductor ETFs have become a focal point for traders and investors assessing the durability of the artificial intelligence (AI) boom, and two of the most closely followed funds are the Invesco PHLX Semiconductor ETF (SOXQ) and the iShares Semiconductor ETF (SOXX). Although both offer concentrated exposure to leading U.S.-listed chipmakers, their differences in cost, size, liquidity, and portfolio construction can materially affect an investor's experience. This stock comparison is especially relevant for those weighing relative performance, market positioning, and risk in a sector that has experienced sharp volatility in recent weeks.

SOXQ Overview and Recent Performance

The Invesco PHLX Semiconductor ETF (SOXQ) seeks to track the PHLX Semiconductor Sector Index, a market-capitalization-weighted benchmark of roughly 30 to 31 U.S.-listed semiconductor design, manufacturing, and equipment companies. Launched in June 2021, the fund carries a competitive 0.19% expense ratio and had approximately $3 billion in assets as of recent reporting. Its largest positions have historically included NVIDIA, Broadcom, and Micron, reflecting a pronounced tilt toward AI-related chip leaders.

In recent weeks, SOXQ has moved in line with the broader semiconductor complex, which sold off sharply as investors reassessed the sustainability of AI data-center spending and reacted to firmer inflation data. Despite that pullback, the fund has retained a strong year-to-date advance, supported by robust demand for advanced chips and high-bandwidth memory. Its relative performance remains closely tied to the handful of mega-cap names that dominate its portfolio.

SOXX Overview and Recent Performance

The iShares Semiconductor ETF (SOXX), managed by BlackRock, tracks the ICE Semiconductor Index (formerly the NYSE Semiconductor Index), a basket of approximately 30 U.S.-listed chipmakers. In operation since 2001, it is one of the largest and most liquid semiconductor ETFs, with roughly $45 billion in assets and an expense ratio near 0.35%. Its top holdings have recently included AMD, Intel, NVIDIA, Micron, and Broadcom, with the top five positions representing about 40% of the portfolio.

Like SOXQ, SOXX has faced notable selling pressure in recent market activity. The fund extended a multi-session losing streak as concerns mounted over AI capital expenditure and higher borrowing costs, falling roughly 25% from its mid-2026 peak before a partial rebound. Even so, SOXX remains up substantially year to date and continues to draw elevated trading volume as institutional and retail investors reposition.

Head-to-Head Comparison

The most immediate contrast between SOXQ and SOXX is scale and cost. SOXX commands vastly greater assets and daily dollar volume, offering tighter liquidity for large orders and a two-decade track record. SOXQ, by comparison, is a newer, smaller fund but charges a materially lower expense ratio, which can benefit long-term holders seeking cost efficiency.

Their portfolios also differ subtly despite near-perfect correlation. SOXQ's index has leaned more heavily on NVIDIA, Broadcom, and Micron, whereas SOXX has carried larger relative weights in AMD and Intel. These weighting differences can translate into modest divergence in relative performance during rotations among individual names. On risk, both funds carry high concentration and elevated volatility tied to AI-spending sentiment, interest-rate expectations, and memory-market cycles.

Tickeron AI Verdict

Based on observable factors such as trend consistency, cost structure, liquidity, and portfolio positioning, Tickeron's AI would likely view SOXX as the more stable, institutionally established vehicle in the current environment, given its superior liquidity and longer operating history. However, SOXQ's lower expense ratio and slightly different top-holding tilt could appear marginally more favorable for cost-conscious investors seeking concentrated exposure to leading AI-chip names. Because the two funds correlate so closely, any AI-based preference is likely to hinge on short-term trend signals and relative strength rather than a decisive structural advantage.
