Overview
SMH and XSD are both semiconductor-focused equity ETFs tracking the same industry, but they differ fundamentally in index construction and liquidity. SMH tracks the MVIS US Listed Semiconductor 25 Index — a capped portfolio of 25 large-cap semiconductor names — while XSD tracks the S&P Semiconductor Select Industry Index, which covers a broader swath of the sector. SMH has $66.4B in assets and has been running since 2011; XSD holds $2.53B and launched in 2006.
How they differ
The biggest distinction is index breadth: SMH's 25-name concentration versus XSD's broader exposure. This shows up directly in beta — SMH reports 2.05, XSD 2.77 — suggesting XSD's wider constituent base adds volatility, possibly because it captures smaller or more cyclical semiconductor names that amplify sector swings. Both charge the same 0.35% expense ratio and pay minimal distributions (0.19% and 0.19%), so the cost difference is negligible. The real gap is size: SMH's $66.4B in AUM dwarfs XSD's $2.53B, meaning SMH offers tighter spreads and deeper liquidity for most retail and institutional investors.
Who each is best for
SMH: Fits investors seeking broad large-cap semiconductor exposure through a liquid, low-cost vehicle. The 25-name index design and massive AUM appeal to those who want sector participation without extreme volatility or the need to hand-pick individual chips stocks.
XSD: Designed for investors comfortable with higher volatility in exchange for potentially broader sector capture. The narrower AUM and higher beta may suit those with longer time horizons who want exposure beyond the mega-cap semiconductor names SMH emphasizes.
Key risks to know
- Sector concentration. Both ETFs are entirely dependent on semiconductor industry health — any downturn in chip demand, supply-chain disruption, or geopolitical pressure (especially around Taiwan) can drive sharp losses for either fund.
- Amplified market sensitivity. XSD's beta of 2.77 means it swings nearly three times as hard as the broad market during downturns; SMH's 2.05 beta is still elevated and leaves little room for defensive positioning.
- Index construction gap. SMH's cap-weighted 25-name approach concentrates risk in the largest players (likely NVIDIA, Intel, TSMC exposure); XSD's broader index may diversify that somewhat but introduces exposure to smaller firms with higher failure risk in down cycles.
- Minimal income potential. With distribution rates of 0.19% and 0.19%, neither ETF is held for yield. Investors relying on distributions will be disappointed; total return depends almost entirely on price appreciation.
Bottom line
If you want maximum liquidity and large-cap semiconductor exposure with tighter volatility, SMH's $66.4B asset base and lower beta stand out. If you're willing to accept higher sector-wide swings and prefer a broader definition of "semiconductor," XSD's wider index may suit a longer-horizon allocation — but confirm its constituent overlap with SMH aligns with your holdings elsewhere. Past performance in semiconductors has been outsized; neither fund hedges against the cyclicality inherent in the space.
