Shares of Novavax (+4.5%) and Merck (+1.2%) both lifted after they announced separate plans to develop and test COVID-19 vaccines. But reports that the US was considering sanctions on Chinese firms and officials over the situation in Hong Kong reduced index gains. At the close of trade, the Dow Jones index rose by 530 points or 2.2%. The S&P500 index was up by 1.2%. And the Nasdaq index rose by 15 points or 0.2%.
