"This is a classic case of 'buy the rumor and sell the news'," said Adam Sarhan, chief executive of Sarhan Capital in New York.
"Over the last few weeks, stocks had soared in anticipation of more easy money, and now that we've got the news, stocks are selling off," Sarhan said.
Crude prices, the stock market's other major driver, fell after Reuters reported that a proposed meeting between major oil producers to discuss an output cut was unlikely to take place without Iran's participation. Brent crude was off more than 2 percent.
