New York stock exchanges opened for profit on Monday, despite the worldwide record increase in corona infections.
Investors are looking forward to the start of the quarterly season on Wall Street this week. The chip sector is also attracting attention because of significant takeover news.
The Dow-Jones index was 0.9 percent higher at 26,294 points shortly after the start. The broad S&P 500 rose 0.8 percent to 3,210 points, and technology exchange Nasdaq climbed 1.4 percent to 10,767 points.
Soft drink and snack manufacturer PepsiCo came with numbers. Turnover fell less sharply than expected, partly because more chips like Cheetos were bought by people who were at home because of the corona crisis.
PepsiCo did not forecast for the whole of 2020 due to the uncertainties surrounding the virus outbreak. The stock climbed 0.3 percent.
Pharmaceutical Pfizer was green for almost 3 percent. The US regulator FDA is launching an accelerated review process for two experimental corona vaccines that Pfizer is developing with German biotechnologist BioNTech.
