Small stocks fared worse than large ones Monday.
The Russell 2000, a benchmark of small-company stocks, fell 1.3 percent to 938.78, paring its gain for the year to 10.5 percent. It was the index's biggest decline in more than a month. The Nasdaq composite fell 28.35 points, or 0.9 percent, to 3,239.17.
April is historically the second-strongest month for stocks, Deutsche Bank analysts said in report released Monday. The S&P 500 has gained an average of 1.4 percent in April, based on returns since 1960, making it the second strongest month after December.
The last meaningful setback for stocks started before November's election. The market slid 6 percent between Oct. 1 and Nov. 15 in the run-up to the vote and immediately afterwards on concerns that Washington would be unable to enact reforms to keep the economy growing.
Evidence that growth is continuing, despite the political tensions in Washington, have kept stocks on an upward trajectory since then, leaving investors waiting for dips to add to their holdings.
"I'd love to have some sort of a pullback here because I'd think it's an opportunity," said Scott Wren, an equity strategist at Wells Fargo Advisors. "But it doesn't feel like we're going to have one in the near term."
The yield on the 10-year Treasury note, which moves inversely to its price, fell to 1.84 percent from 1.85 percent.
Markets were closed in observance of Good Friday last week. European markets were closed Monday for Easter.
