Tech Rout Spurs Second-Biggest Quarterly ETF Outflow on Record

The plunge that pushed technology stocks to their worst quarter in a decade prompted exchange-traded fund investors to flee the sector at the second-fastest pace on record.

In all, they’ve pulled $5 billion from tech-focused ETFs since the start of October. That’s the biggest quarterly outflow since the $6 billion withdrawn during the period that ended in March 2016, according to data compiled by Bloomberg. About $3.5 billion was pulled in November alone, a month that saw huge declines in bellwethers including Apple Inc. and Nvidia Corp.
