Health care and biotech stocks fell sharply after President-elect Donald Trump attacked the industry during his press conference Wednesday.
"We have to get our drug industry coming back. Our drug industry has been disastrous, they're leaving left and right. They supply our drugs but they don't make them here, to a large extent," Trump said.
"And the other thing we have to do is create new bidding procedures for the drug industry, because they're getting away with murder," he said.
The iShares Nasdaq Biotechnology ETF (IBB) briefly fell more than 2.5 percent, tracking for its first negative day of 2017. The health care SPDR (XLV) declined around .96 percent, with Endo International falling around 8.6 percent, Perrigo down more than 6 percent and Mallinckrodt down more than 7 percent.
Health care dropped more than 1.5 percent as the worst performer in the S&P 500, with the pharmaceuticals sub-sector down more than 1.5 percent and the biotechnology sub-sector off nearly 3 percent.
