Tech ETF Hit by the Largest Outflows Since the Dot-Com Crash

The rout in U.S. stocks last week spurred the heaviest withdrawals since the 2000 dot-com crash for the biggest exchange-traded fund tracking U.S. technology shares.

Investors yanked almost $4 billion from the $56 billion PowerShares QQQ Trust Series 1 ETF in the five days ended Feb. 9, outpacing redemptions at the depths of the financial crisis. The SPDR S&P 500 ETF Trust, the world’s biggest fund, saw a record $23.6 billion of outflows.
