Stocks fell sharply Monday, retreating after back-to-back weekly gains, as a historic decline in U.S. crude prices raised concerns about the economic damage being done by coronavirus shutdowns. A delay in funding the for the depleted small business rescue loan program also weighed on sentiment. The Dow Jones Industrial Average closed 592.05 points lower, or 2.5%, 23,650.44. The S&P 500 slid 1.8% to 2,823.16. The Nasdaq Composite pulled back 1% to 8,560.73. (Click here for the latest market news.)

The May contract for West Texas Intermediate, which expires on Tuesday, plunged more than 100% to settle at negative $37.63 per barrel, a bizarre move tied to weak demand outlook and storage capacity issues. The negative impact on stocks from oil likely would have been worse were it not for lesser declines in oil contracts expiring during future months. WTI's June contract slid over 15.6% to $21.09 per barrel. July's oil contract was down 6.9%. It was a strange phenomenon that analysts chalked up to the collapse in demand for oil contracts expiring this week. Refineries don't need the oil and are near storage capacity with most of the country shut down. The negative price means producers will pay to take this oil off their hands. "The moves in the oil market are really just unbelievable now that we are literally running out of storage space," Peter Boockvar, chief investment officer at Bleakley Advisory Group, said in a note. "I do believe that these types of moves is what bottoms are made of and in May and June when things start to reopen again it will go a long way in helping along with the production cuts."
