US equities tumbled on Monday as fading stimulus hopes slammed investor sentiments.

House Speaker Nancy Pelosi established a 48-hour deadline on Sunday for the White House and Democrats to reach a compromise on fresh fiscal relief. She and Treasury Secretary Steven Mnuchin held multiple talks over the weekend on a deal.

While the White House hasn't yet officially upped its $1.8 trillion counteroffer to Pelosi's $2.2 trillion proposal, President Donald Trump repeated calls for a deal larger than the two options.

Stocks extended their slide in the afternoon after Pelosi told Democrats that significant disagreements between the party and the White House remain. With a single day left for the two to reach a deal, optimism for pre-election stimulus is all but dead.

Here's where US indexes stood at the 4 p.m. ET market close on Monday:

• S&P 500: 3,426.92, down 1.6%
• Dow Jones industrial average: 28,195.42, down 1.4% (411 points)
• Nasdaq composite: 11,478.88, down 1.7%

Even if a deal is reached ahead of the Tuesday deadline, Senate Republicans are set to kill the package. Senate Majority Leader Mitch McConnell plans to bring a $500 billion measure to a vote on Tuesday and continues to oppose any larger measure. Democrats are set to block the piecemeal bill, essentially leaving both parties stuck in attempts to pass their own packages.

"It seems politicians are determined to show that they are trying to get the next additional stimulus package done, but no one should count on action this year," Edward Moya, senior market analyst at Oanda, said.

Concerns around rising COVID-19 case counts throughout the US also weighed on valuations. Daily new cases surpassed 50,000 for five days in a row, reigniting fears of a second lockdown or stymied economic growth.

Global cases tore above 40 million on Monday, further fueling anxiety around a prolonged economic slump.

The Monday slump follows a small rally that closed out last week. Stocks gained on Friday after retail sales beat expectations in September, signaling stronger-than-expected consumer spending trends heading into the holiday season. The University of Michigan's consumer sentiment gauge also beat estimates for a preliminary October reading, adding to hopes that the US economic recovery can continue without near-term fiscal support.

Tesla initially gained after Wedbush analysts raised their price target for the stock to $500, implying a 14% rally from Friday's close. The team praised the automaker's better-than-expected deliveries in the third quarter, adding Tesla is on track to hit 500,000 deliveries this year. Still, the broader market downturn dragged on Tesla through the afternoon.

Spot gold rose as much as 1% to $1,918.61 per ounce before paring gains. Treasury yields climbed and the US dollar fell against a basket of major peers.
