A historic surge of cash has swept into exchange-traded funds, spurring asset managers to launch new trading strategies that could be undone by a market downturn.
This year’s inflows into ETFs world-wide crossed the $1 trillion mark for the first time at the end of November, surpassing last year’s total of $735.7 billion, according to Morningstar Inc. data. That wave of money, along with rising markets, pushed global ETF assets to nearly $9.5 trillion, more than double where the industry stood at the end of 2018.
