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

Overview

SMH and SPMO are both equity ETFs tracking concentrated factor indexes, but they serve fundamentally different sector and strategy purposes. SMH provides pure-play exposure to the semiconductor industry through 25 specialized chip and semiconductor equipment makers, while SPMO targets momentum characteristics across the broader S&P 500 using the same index universe but filtering for companies with the strongest price momentum. The choice between them hinges on whether you want semiconductor-specific cyclical upside or broad-market exposure tilted toward outperforming equities.

How they differ

The core difference is universe and focus: SMH limits its 25 holdings to semiconductor and chip-equipment companies—a single industry bet with significant concentration—while SPMO starts with the full S&P 500 and selects the 100 or so names exhibiting the strongest momentum characteristics across all sectors. This means SMH is far more vulnerable to cyclical semiconductor downturns, whereas SPMO's exposure is diversified by sector but concentrated among recent outperformers.

The second key difference is valuation sensitivity. SMH trades with a beta of 2.05, roughly twice the market's moves, reflecting the leverage inherent in holding high-beta growth and cyclical semiconductor stocks. SPMO's beta of 1.33 indicates it amplifies market moves by about a third while maintaining broader diversification.

Fee and yield profiles diverge as well. SMH charges 0.35% annually and yields just 0.19% (distributed annually), reflecting the low-dividend nature of growth semiconductor firms. SPMO costs 0.13% and yields 0.64% quarterly, a structure more typical of broad-market equity funds. SPMO's $21.3B in AUM is smaller than SMH's $71.5B, but both funds have substantial scale.

Who each is best for

SMH: Fits investors with strong conviction in semiconductor demand—whether from AI infrastructure build-out, data center cycles, or geopolitical supply-chain reshoring—who can tolerate 2x market volatility and want concentrated exposure to a single transformative industry rather than broad-market diversification.

SPMO: Designed for growth-oriented investors who believe momentum factors have persistent edge within the S&P 500 and want to capture outperforming large-cap names without sector concentration or extreme beta sensitivity, accepting that momentum strategies can lag during mean-reversion phases.

Key risks to know

• Semiconductor cycle risk: SMH's 25-stock semiconductor and equipment focus means earnings downturns, inventory corrections, or margin compression in chip production ripple through the entire fund with no sectoral diversification buffer. The fund's 2.05 beta amplifies these moves sharply.

• Momentum mean reversion: SPMO's selection of the S&P 500's recent outperformers exposes it to sharp reversals when leadership rotates away from momentum stocks toward value or lower-beta names. This risk is structural to the strategy, not temporary market noise.

• Overlap in technology exposure: Both funds carry meaningful exposure to semiconductor and AI-adjacent large-cap technology stocks, so their returns may correlate more than their different indexes suggest, limiting diversification if held together.

• Quarterly versus annual distribution tax timing: SMH's annual distribution creates a single tax event each year and can concentrate gains, while SPMO's quarterly payouts spread the realization across the calendar, though this matters less in tax-advantaged accounts.

Bottom line

If you believe semiconductors are entering a structural growth phase and want maximum leverage to that thesis, SMH's concentrated play and higher beta offer that exposure; if you prefer momentum factor exposure within the broader market with lower fees and less cyclical concentration, SPMO provides that framework. Both are liquid, low-cost vehicles, but they're solving different allocation problems, and past performance in either strategy does not predict future results.
