According to @EricBalchunas, while ETFs overall took in $1.5 trillion in 2025, small-cap ETFs saw net outflows, indicating investor preference away from small-cap exposure (source: @EricBalchunas, Jan 9, 2026). He reports large caps have outperformed for five consecutive years, with small-cap allocations at a decade low and new small-cap ETF launches drying up, underscoring persistent dominance of large-cap factors over small caps (source: @EricBalchunas, Jan 9, 2026).
