Pfizer shares sank after President Donald Trump blasted the pharmaceutical giant on Twitter for increasing the price of 100 drugs and treatments, according to The Wall Street Journal.
"Pfizer & others should be ashamed that they have raised drug prices for no reason," President Trump tweeted at 12:08 p.m. July 9.
The company's stock value saw an initial plunge shortly after the tweet on July 9 — but a few hours later, they recovered. The drugmaker's shares were up 0.3 percent at 2:17 p.m. that same day.
President Trump has promised action to combat high drug prices in recent months. In May, the Trump administration issued a 44-page blueprint detailing his strategy to lower prices. Critics said the administration's plan lacks aggressive maneuvers and likely won't help Americans pay less for their prescriptions.
