After opening higher, the market continued to rally. At midday, the Dow traded 2.2%, or nearly 600 points, higher, while the S&P 500 -- Wall Street's broadest measure -- climbed 2%. The Nasdaq Composite was up 1.9%.
Last week, all three indexes recorded their worst weeks since March on uncertainty about rising Covid-19 infections, the prospect of government stimulus and the election results.
Betting markets continue to favor former Vice President Joe Biden to win the election, with PredictIt putting his chances at 64%.
Analysts at Goldman Sachs think there's a decent chance the winner will be declared Tuesday night because swing states like Florida, Arizona, Georgia and North Carolina will report results quickly.
This is key for the stock market, which hates uncertainty. Not knowing the winner for days has been dubbed the "nightmare scenario" by investors.
Financial markets have been moving on hopes -- and then dashed hopes -- for more fiscal stimulus out of Washington for months now, and investors expect a bigger stimulus package under a Democratic administration.
"I think [the market is up on] two things: some retracing from last week['s losses], but I also think there's a sense that no matter who wins there will be some short-term money coming, whether it's stimulus or infrastructure," said JJ Kinahan, chief market strategist at TD Ameritrade.
The US economy has started on its long road to recovery, but economists and central bankers agree that more government spending will be needed to keep the improvements going.
Meanwhile, President Donald Trump said Tuesday morning on "Fox & Friends" he believed the market was up because investors were pricing in another term for him.
Trump has repeatedly said the market would sell off if Biden was elected, even though market participants have refuted this thesis because of the expected government spending to boost the recovery.
