May 28 (Bloomberg) -- U.S. stocks slid, capping the worst May for the Dow Jones Industrial Average since 1940, while the euro slumped and Treasuries rose as a downgrade of Spain’s debt rating and escalating tensions on the Korean peninsula triggered a flight from riskier assets.

“Spain’s downgrade just adds to more uncertainty,” said Quincy Krosby, chief market strategist for Newark, New Jersey- based Prudential Financial Inc., which oversees about $667 billion. “There are too many geopolitical events. We have a three-day weekend in the U.S., and traders will definitely want to lighten their books.”

‘All-Out War’

Losses in U.S. stocks widened earlier after North Korean Major General Pak Rim Su disputed the results of the international investigation that found his nation sank a South Korean warship. “Any accidental clash that may break out in the waters of the West Sea of Korea or in areas along the Demilitarized Zone will lead to all-out war,” he said, according to North Korea’s official news organization.
