Semiconductor ETFs have officially entered historically uncharted territory. The VanEck Semiconductor ETF (SMH) and the iShares Semiconductor ETF (SOXX) have logged more large single-day price swings in 2026 than any prior year on record, with at least 34 daily moves exceeding 4%.
The numbers behind the chaos
BTIG analyst Jonathan Krinsky flagged the phenomenon directly, noting that SOXX recorded daily swings of at least 3.9% on multiple occasions throughout the year.
The wild price action comes alongside returns that look almost too good to be true. SMH delivered more than 62% on a year-to-date basis in 2026. SOXX, at its peak, approached 89% for the year. Both figures reflect demand for AI-adjacent hardware that has essentially rewritten how markets value the semiconductor supply chain.
The money flows match the momentum. SOXX pulled in a record single-day inflow of $5.4 billion in July 2026, a number that would be remarkable for any fund, let alone one that focuses on a single industry subsector.
