SMH vs SOXX: Which Is the Better Pick in 2026?

Overview

SMH and SOXX are both semiconductor-focused equity ETFs tracking different US-listed semiconductor indexes. SMH follows the MVIS US Listed Semiconductor 25 Index (25 holdings), while SOXX tracks the broader ICE Semiconductor Index. The key distinction is index breadth: SMH concentrates on the 25 largest semiconductor names, while SOXX casts a wider net across the sector.

How they differ

SMH's tighter index—25 holdings versus SOXX's broader roster—means SMH carries higher concentration risk but potentially lower overlap with broad tech benchmarks. Both ETFs charge an identical 0.35% expense ratio, making fees a wash. SOXX has a higher beta of 2.32 versus SMH's 2.05, suggesting SOXX amplifies market moves more sharply. Distribution yields are nearly identical at 0.19% for SMH and 0.21% for SOXX, though SOXX pays quarterly while SMH distributes annually. SMH is significantly larger at $71.5B in AUM compared to SOXX's $47.6B, reflecting longer establishment in the current market cycle (though SOXX's inception in 2001 predates SMH's 2011 launch).

Who each is best for

SMH: Fits investors who want concentrated exposure to mega-cap semiconductor leaders and can tolerate the amplified volatility that comes with a 25-name index.

SOXX: Fits investors seeking broader semiconductor-sector diversity and prefer the smoother return profile that additional holdings and slightly lower beta may provide, relative to SMH's tighter focus.

Key risks to know

• Concentration in large-cap semiconductor cyclicality. Both ETFs carry high beta (2.05–2.32), meaning they will likely amplify downturns in chip-cycle weakness or semiconductor demand shocks. A sustained industry downturn will exert outsized pressure on both funds.

• SMH's narrower index increases single-name impact. With only 25 holdings, SMH's performance can be materially swayed by the operational or valuation stumbles of any one or two mega-cap positions. SOXX's broader index dilutes that single-name risk.

• Low distribution yield masks growth-driven strategy. Both funds yield under 0.25% annually, indicating these are capital-appreciation vehicles with minimal income generation. Investors relying on dividend income should look elsewhere; these are sector bets, not income sources.

• Technology sector correlation. Both SMH and SOXX holdings likely overlap significantly with each other and with broader technology indexes. Verify overlap if building a diversified portfolio; holding both may introduce redundancy.

Bottom line

If you're tilting toward the sector's largest players and can accept higher volatility, SMH's tighter focus and larger asset base offer liquidity and simplicity. If you prefer modestly broader sector exposure with a marginally lower beta, SOXX's longer history and quarterly distributions may feel less volatile. Both are sector concentrations, not diversified plays; the choice hinges on whether you want the tightest 25 or a wider semiconductor net.
