Active ETFs hit $966 billion in global assets, doubling in 18 months. Traditional mutual funds and boutique shops drive the shift. Tax advantages and transparent holdings win flows. The category is on pace to clear $1 trillion.
Actively managed exchange-traded funds hit $966 billion in global assets at the end of the first quarter, according to Morningstar data cited by a recent industry report. That figure has roughly doubled in 18 months. The growth is not coming from passive managers adding an active sleeve. Traditional active mutual fund firms – Fidelity, Dimensional Fund Advisors, Capital Group – are converting their best-performing strategies into ETF wrappers. Capital Group turned its $260 billion American Funds franchise into ETFs starting in 2021. Fidelity now runs more than $70 billion in active ETFs. Dimensional, which resisted the format for years, has pulled in over $30 billion since its first ETF launch in 2020.
A second wave comes from the other direction. Boutique research shops and quantitative managers who never ran a mutual fund are launching ETFs as their primary vehicle. Roughly a third of the 1,900 active ETFs on the U.S. market launched in the last 12 months, the Morningstar data showed. Many of them hold concentrated portfolios of 20-40 stocks, not the 200-plus names typical of an index fund.
The mechanics matter. An active ETF discloses its holdings daily – the same transparency that made passive ETFs successful – the manager can trade without announcing each move. That structure, known as non-transparent active ETF, never attracted serious flows. The winners are fully transparent active ETFs where the manager publishes the full portfolio every day. Investors decided that daily disclosure is a feature, not a bug.
Fees are falling, although not as fast as on the passive side. The average active ETF charges 0.60% in expense ratio, against roughly 0.03% for the biggest S&P 500 index ETFs. That 57-basis-point gap shrinks when you factor in capital gains. Active mutual funds pass taxable gains to shareholders when the manager rebalances. Active ETFs, like their passive cousins, use the creation-redemption mechanism to keep capital gains inside the fund. Over a five-year horizon, that tax advantage can offset the entire fee difference for a taxable investor.
The category is still small relative to the $8 trillion U.S. ETF market and the $19 trillion mutual fund complex. The trend line is steep. Net inflows into active ETFs hit $165 billion in 2024, more than double the prior year. At that pace, the category will clear $1 trillion before year-end. The broader market should take the signal. Active fund managers who refuse to offer an ETF version are ceding distribution to those who will.
