U.S. Stocks, Oil, Euro Tumble; Dow Ends Worst May Since 1940

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.

The Dow tumbled 122.36 points, or 1.2 percent, to 10,136.63 at 4 p.m. in New York and lost 7.9 percent this month. The Standard & Poor’s 500 Index sank 1.2 percent to 1,089.41, led by financial shares on the Spanish downgrade and energy companies after U.S. President Barack Obama extended a moratorium on new deep-water drilling. Oil erased gains after rallying as much as 1.6 percent to more than $75 a barrel. Ten-year Treasury yields decreased 7 basis points to 3.3 percent. The euro slipped 0.7 percent to $1.2273. (more)
