Wall Street Rises as Easing Yields, Moderna Boost Healthcare
U.S. stocks went up a little on Wednesday.
Bond yields fell after the Treasury announced larger support operations for longer-term bonds.
Lower yields can make investors more willing to buy riskier assets.
Moderna’s stock jumped after it reported encouraging results for a personalized cancer treatment.
The treatment reduced the risk of melanoma returning or spreading in a late-stage trial.
Other healthcare companies, including Merck, Novavax, and BioNTech, also saw their shares rise.
Healthcare stocks became the strongest-performing major sector.
Investors were still cautious because Federal Reserve officials discussed possibly raising interest rates if inflation stays too high.
U.S. stock indexes rose modestly as government bond yields eased and investors’ risk appetite improved.
Moderna shares surged more than 137% after reporting positive late-stage melanoma-treatment trial results.
Merck gained about 12%, while Novavax rose more than 8% and BioNTech climbed 19%.
The S&P 500 healthcare sector rose more than 3% to a record high, leading gains among major sectors.
Federal Reserve minutes showed several policymakers open to raising rates if inflation fails to reach the 2% target.
