Wall Street's three major indexes hit record highs on Monday as the first positive data from a late-stage Covid-19 vaccine trial prompted hopes that an economic recovery from the pandemic-driven crisis was finally in sight.
Oil prices surged more than 8% and pushed up energy stocks while US Treasuries sold off after US drugmaker Pfizer and its German partner BioNTech said a large-scale trial of their vaccine showed it was more than 90% effective in preventing Covid-19.
Saturday's news that Joe Biden had won the US presidential election was also a reassuring confirmation of what investors had already been counting on by the end of last week, according to market strategists.
"Election uncertainty is fading into the rearview mirror. Now we have this boost of investor enthusiasm after the vaccine news," said to Michael Antonelli, market strategist at Baird in Milwaukee.
"All the types of companies that would benefit from us returning to a pre-Covid world are the big winners today." Sectors such as energy, travel and financials which were among the hardest hit by lockdowns aimed at curbing the virus were the biggest percentage gainers on Monday.

While the vaccine study is still ongoing, Pfizer and BioNTech said they had found no serious safety concerns so far and expected to seek US emergency use authorization later this month.
