Oct 20 (Reuters) - Wall Street's main indexes rose on Tuesday as investors hoped for more stimulus from Washington, with Senate Republicans preparing to vote on a bill to help small businesses hammered by the COVID-19 pandemic.

House of Representatives Speaker Nancy Pelosi and Treasury Secretary Steven Mnuchin will also talk again on Tuesday, after a 53-minute telephone conversation on Monday "continued to narrow their differences" about the coronavirus aid package, a Pelosi spokesman said on Twitter.

"It's mostly hopes that we are going to get a stimulus deal going today and we will have money in the pockets of majority of Americans who are suffering most from the pandemic," said David Trainer, chief executive officer of New Constructs, an investment research firm.

Uncertainty over the fiscal stimulus weighed on Wall Street's main indexes on Monday and analysts expect market turbulence to increase with only two weeks left until Election Day.
