Even exchange-traded fund investors are afraid of Amazon.com Inc.
Health care stocks plunged as much as 6% on Thursday, led by declines in retail pharmacies and drug distributors, after Amazon agreed to acquire online dose-sorting pharmacy PillPack Inc. That spurred massive trading volumes in an exchange-traded fund stuffed with pharmaceutical middlemen, as investors pulled their cash off the table.
The iShares U.S. Healthcare Provider ETF, or IHF, absorbed over $255 million worth of trades on Thursday, the most in almost a decade and a whopping 46 times the average daily turnover for the past year. Investors also pulled more than $44 million from the fund, the most since October.
