FYI: The rapid growth of exchange-traded funds — which track a stock index, or some other group of assets — has fed speculation about what happens in the next big market collapse: Will ETF values still rise and fall with the companies' underlying fund? Or will investors find themselves with devalued ETFs that become tough to unload, except at a discount to the stocks their prices are supposed to be based on?
ETF assets — an industry dominated by New York-based BlackRock's iShares, Vanguard Group of Malvern, and State Street Boston Corp. — grew from under $1 trillion before the 2008-09 recession, to $5 trillion as of June, according to the ETF research and consulting group ETFGI. But new purchases slowed earlier this year to half of 2017 levels as stock market gains slipped.
