Overview
SOXQ and SOXX are both ETFs tracking US semiconductor companies, but they follow different indexes and have meaningfully different cost structures and asset bases. SOXQ tracks the PHLX SOX Semiconductor Sector Index via Invesco, while SOXX tracks the ICE Semiconductor Index via iShares. The two indexes likely overlap substantially in holdings but may weight them differently, and their fee gap—0.19% for SOXQ versus 0.35% for SOXX—compounds over time despite SOXX's much larger asset base of $47.6B.
How they differ
The single biggest difference is cost: SOXQ's 0.19% expense ratio undercuts SOXX's 0.35% by 16 basis points annually. That 84% cost advantage favors SOXQ for buy-and-hold investors, though SOXX's $47.6B in AUM dwarfs SOXQ's $2.86B, which may translate to tighter trading spreads and deeper liquidity for SOXX in practice. Both ETFs exhibit similar beta around 2.27–2.32, indicating comparable volatility relative to the broader market. The yield difference is modest—SOXQ pays 0.32% and SOXX 0.21%—but that gap may reflect index composition or distribution timing rather than a strategic yield play, since both are quarterlies. SOXQ launched in June 2021, making it significantly newer; SOXX has tracked semiconductors since July 2001.
Who each is best for
- SOXQ: Fits investors who want direct semiconductor exposure with minimal drag and are comfortable with a younger, smaller-AUM fund; cost sensitivity is a primary driver.
- SOXX: Fits investors who prioritize established track record and want the liquidity and name recognition that comes with the larger asset base and two-decade history in the space.
Key risks to know
- Both ETFs carry a beta near 2.30, meaning they amplify broad market swings by roughly 2.3×, making them volatile holdings during downturns; semiconductor sector volatility itself adds another layer.
- The two track different semiconductor indexes (PHLX SOX vs. ICE), so their top holdings and weightings likely diverge. Without detailed overlap data, investors cannot assume they move in lockstep; subtle index-methodology differences can produce divergent returns over years.
- Semiconductor fundamentals—cyclicality, geopolitical supply-chain risk (Taiwan concentration, US-China chip competition), fab capacity swings—affect both equally. Neither ETF hedges sector-specific downturns.
- SOXQ's smaller AUM may result in wider bid-ask spreads in lower-volume periods, creating a hidden execution cost that could offset its fee advantage for frequent traders.
Bottom line
If minimizing fees is a priority, SOXQ's 0.19% expense ratio offers a clear edge; if you value a large, well-established fund with a 20-year track record and likely better trading conditions, SOXX's scale and tenure stand out. Both are high-beta semiconductor plays—the choice hinges on fee tolerance and liquidity needs rather than exposure philosophy. Past performance does not predict future results.
