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

Overview

HBMX and SOXX are both semiconductor-focused equity ETFs, but they differ fundamentally in scope and approach. SOXX is a broad-market index fund tracking the entire US semiconductor industry via the ICE Semiconductor Index, while HBMX is a concentrated, actively managed fund targeting a narrower slice—companies in the memory semiconductor ecosystem (DRAM, NAND, and high-bandwidth memory) plus their upstream suppliers in advanced packaging, testing, and equipment. That focus on memory and AI infrastructure is the key distinction.

How they differ

The biggest difference is strategy: SOXX holds a diversified basket of semiconductor companies across logic, memory, equipment, and services; HBMX deliberately narrows that universe to memory-related players and their supply chain. SOXX exhibits 2.33 beta, reflecting the semiconductor sector's sensitivity to economic cycles and technology demand shifts.

Who each is best for

• SOXX: Fits investors seeking broad exposure to the entire semiconductor supply chain—chip designers, manufacturers, equipment makers, and testing services—with a preference for low costs and passive index exposure over active stock picking.

• HBMX: Fits investors with a conviction that memory semiconductors and AI-adjacent infrastructure will outperform the broader chip sector, and who are comfortable with concentrated, manager-driven portfolio construction and higher expense drag in pursuit of that theme.

Key risks to know

• Concentration and single-theme risk. HBMX's explicit focus on memory and HBM creates meaningful exposure to a subsector that can move independently of the broader semiconductor market. Memory chip cycles are notoriously volatile; weakness in DRAM or NAND demand can hurt multiple holdings at once, whereas SOXX's diversification across logic, analog, and equipment buffers sector-specific shocks.

• Active management and tracking error. HBMX's active strategy introduces the risk that portfolio decisions lag the broader memory opportunity or miss it entirely. Concentrated bets on specific packaging or testing names carry idiosyncratic risk that an index approach does not.

• Valuation and cycle timing. Both funds are leveraged to semiconductor demand, but HBMX's memory-specific angle means it may suffer sharper drawdowns when AI infrastructure spending slows or memory oversupply emerges. The fund's youth (inception 06/02/2026) offers no track record through a full cycle.

Bottom line

If you want diversified, low-cost exposure to the entire semiconductor ecosystem with decades of history, SOXX's index approach and $42.3B in assets align with that objective. If you believe memory semiconductors and AI packaging will outpace logic and are willing to pay higher fees and accept concentration risk for that bet, HBMX's thematic focus may match your conviction—though its small size and newness carry material liquidity and sustainability concerns. Neither approach guarantees future performance; the semiconductor cycle remains unpredictable.
