The S&P 500 snapped its worst losing streak in decades and the Dow Jones Industrial Average returned above 18,000 as confidence in an election win for Hillary Clinton inspired market bulls.
The S&P 500 was up 2.22%, the Dow climbed 2.08%, up 371 points, and the Nasdaq jumped 2.37%. Stocks had previously fallen for nine straight sessions with the S&P 500 suffering through its longest losing streak in more than 35 years.
FBI Director James Comey updated Congress on Sunday that a new investigation into emails tied to Democratic presidential candidate Clinton would not bring any charges. Wall Street had been on edge for the past week after Comey announced the new investigation, making the results of the U.S. presidential election more of an uncertainty.
Republican presidential candidate Donald Trump's poll numbers had crept higher throughout the week before plateauing at around a 32% chance of winning the presidency, according to FiveThirtyEight. Separate national polls give Clinton a 48% chance to win to Trump's 44%.
Nearly 42 million Americans have already cast their ballots in early voting, a record number which has skewed toward Democrats. Voters head to the polls on Tuesday when election sites officially open.
"Financial markets are going to stay febrile as we enter the last throes of the campaign," Luke Hickmore, senior fixed income fund manager at Aberdeen Asset Management, wrote in a note. "Investors were largely concluding that Hillary would win before the FBI announced it was looking at the new emails last week. With that issue now out of the way, financial markets will probably double down on Hillary winning."
