Shares on Wall Street ended higher on Tuesday amid growing optimism that talks among U.S. lawmakers are progressing with respect to a U.S. stimulus package aimed at cushioning the economic shock from the coronavirus pandemic. House of Representatives Speaker Nancy Pelosi said she was optimistic Democrats could reach a deal with the White House that could get aid out by early next month. She added there should be an indication of a possible agreement later on Tuesday.
"I think no matter who gets elected, we will get the stimulus," said Brian Reynolds, chief market strategist, at Reynolds Strategy.
"The current headlines are short term in nature. Eventually, they would get together and produce more stimulus for the economy because all the sectors that are lagging need it badly," he added.
Uncertainty over the coronavirus aid package weighed on Wall Street's main indexes on Monday and analysts expect market turbulence to increase with only two weeks left until Election Day.
