Why Pfizer and BioNTech Got Thrashed on Thursday
In what hardly qualifies as a surprising development, shares of both Pfizer (NYSE: PFE) and BioNTech (NASDAQ: BNTX) fell in price on Thursday. This was on the back of a Supreme Court decision that struck down a key government vaccination mandate. After the smoke cleared, Pfizer's stock price fell by nearly 2%, while the far smaller and less diversified BioNTech suffered an 8% hit.
