The S&P 500 and the Dow eased from record levels on the first trading day of the year on Monday as nerves over the outcome of runoff elections in Georgia this week countered optimism over a vaccine-driven recovery in the global economy, Reuters reported. The Dow was also dragged down by a near 3% fall in Boeing Co shares after Bernstein cut its rating to "underperform", saying issues with MAX 787 could significantly hurt the U.S. plane maker's free cash flow. The fate of President-elect Joe Biden's agenda including rewriting the tax code, boosting stimulus and infrastructure spending hinges firmly on Tuesday's twin Senate races in the battleground state of Georgia that will determine control of the chamber. U.S. manufacturing activity picked up at its briskest pace in more than six years in December, a survey showed on Monday. It comes on the heels of upbeat factory activity surveys across Europe and Asian earlier in the day. On the vaccine front, Britain on Monday became the first country to roll out the COVID-19 shot developed by Oxford University and AstraZeneca. Some investors are cautious about the pace of economic growth as U.S. jobless claims remain stubbornly high, while a new round of business closures last month and the discovery of a new variant of the coronavirus have cast a shadow on the outlook.
