The tech-heavy Nasdaq 100 Index pared gains, but was still up 0.8%.Pfizer’s Covid Vaccine Prevents 90% of Infections in Large StudyThe preliminary results on the vaccine pave the way for the companies to seek an emergency-use authorization from regulators if further research shows the shot is also safe.Pfizer shares extended gains in premarket trading, rising about 7%. American depositary receipts for BioNTech, which is also developing the vaccine, were up about 11%.The announcement heaped fuel on a rally that’s been running for the past week after the U.S. election.
