Stocks closed mostly higher on Wednesday, helped by big technology stocks, but news of tighter restrictions in New York State helped dent an earlier rally. The index was dragged lower in part by American Express and Walt Disney, two stocks that shot up this week after news of a potentially successful vaccine sent travel, entertainment and tourism companies surging. The Dow declined shortly after news crossed that New York would put restrictions on bars, restaurants and gyms as COVID-19 infections rose in the state.
