Hands on fund managers drive ETF growth

ETF assets have topped $1 trillion year-to-date, with active ETFs driving the bulk of recent growth: active funds account for 80% of year-to-date launches and have seen AUM rise 38% versus 6% for passive ETFs. New ETF launches are balanced between fixed income and equities, and median AUM is materially higher for funds aged two-to-three years (~$120M) versus newer launches (~$40M). Industry participants including Janus Henderson and BlackRock highlight active management’s role in navigating increased stock dispersion and BlackRock expects continued ETF expansion into 2026.

Analysis

Market structure: Active ETF launches (80% of YTD) and AUM growth (active +38% vs passive +6%) concentrate flows into active managers with scale and distribution. Winners are large ETF platforms (BLK) and high-ROA active strategies (JEPI, JPST); losers are small new funds (median AUM ~$40m) and low-fee index providers facing reallocation pressure. Expect fee mix and spread capture to tilt toward incumbents that can absorb liquidity; materially higher stock-level dispersion favors stock-picking strategies over pure beta for the next 6–18 months.

Risk assessment: Tail risks include regulatory changes to ETF transparency/creation rules, mass redemptions from underperforming active ETFs, or a volatility shock that collapses ETF liquidity (low-probability but high-impact). Immediate (days) risk is flow concentration into few tickers; short-term (weeks–months) is closures of subscale funds; long-term (quarters–years) is fee compression and consolidation (favoring BLK, GS). Hidden dependency: platform shelf access (Schwab, Fidelity) and wholesaler incentives — loss of shelf can kill flows quickly.

Trade implications: Favor large, distribution-rich asset managers and volatility/dispersion trades — buy BLK exposure and buy calls on active income ETFs while shorting vanilla passive products. Use options to express asymmetric risk (calendar or vertical spreads over 6–12 months). Rotate into financials and trading desks that benefit from higher single-stock vol; underweight index ETF providers and tiny new ETF issuers.

Contrarian angles: Consensus overlooks scalability limits — average AUM of $120m for 2–3yr funds implies most active ETFs will struggle to scale; market may be over-allocating to a handful of winners. Historical parallel: active mutual fund booms that later consolidated; unintended consequence is increased dispersion and idiosyncratic risk that can blow up concentrated active strategies.

Key Decisions for Investors

• Establish a 1.5–2.5% tactical long position in BLK (BlackRock) over 6–12 months to capture platform share gains; prefer a call-calendar or 12-month call spread (e.g., buy Jan 2027 1,050–1,150 call spread) to cap cost, target +15–25% upside, stop-loss at -8%.
• Initiate a 1% long / 1% short pair: long JHG (Janus Henderson) to play active product launches and distribution gains, short VOO (S&P500 ETF) small notional to express active vs passive rotation; horizon 3–9 months, unwind if BLK AUM growth vs passive growth narrows to <10% year-over-year.
• Deploy a dispersion/volatility trade: buy 3–6 month 25–30 delta call and put spreads on a basket of mid-cap names with high analyst dispersion (allocate 0.5–1% portfolio), or buy an equity-dispersion ETF if available; target realized vol > implied vols by 20% within 3 months.
• Reduce new-ETF exposure: cut or avoid allocations to active ETF launches with AUM < $100m and <24 months track record; re-evaluate only after quarterly AUM growth >25% and platform listing on top-3 retail brokers within 90 days.
