(Reuters) - The S&P 500 and Dow indexes opened nearly flat on Monday as concerns about a jump in COVID-19 cases curbed risk appetite, with investors also hoping for more stimulus to shore up a battered global economy.
Futures tracking both the indexes turned marginally positive shortly before the open, as positive data from U.S. drugmaker Pfizer (N:PFE) and German biotech firm BioNTech (O:BNTX) on their experimental coronavirus vaccine showed it was safe and induced an immune response in patients.
The Dow Jones Industrial Average (DJI) fell 11.66 points, or 0.04%, at the open to 26,660.29, and the S&P 500 (SPX) opened lower by 0.44 points, or 0.01%, at 3,224.29. The Nasdaq Composite (IXIC) gained 22.83 points, or 0.22%, to 10,526.02 at the opening bell.
