The stock market closed out the first three months of the year Tuesday on a down note, erasing much of the gains from the prior day's big rally.
The Dow Jones industrial average slumped 200 points, knocking the blue-chip index slightly lower for the year. The Standard & Poor's 500 index ended the quarter with a meager gain of half a percent.
The broad decline came as traders seized on the final day of the quarter to do some profit-taking and prune their portfolios. Health-care stocks were among the biggest decliners. Oil prices extended their slide.
"It's the end of the quarter," said Anwiti Bahuguna, senior portfolio manager at Columbia Threadneedle Investments. "Today the markets are probably driven by that quite a bit, because people are rebalancing their portfolios."
The Dow fell 200.19 points, or 1.1 percent, to 17,776.12. The 30-company index is down 0.3 percent for the year.
The S&P 500 index slid 18.35 points, or 0.9 percent, to 2,067.89. The index is up 0.4 percent for the year. The Nasdaq composite lost 46.56 points, or 0.9 percent, to 4,900.88. The tech-heavy index ended the quarter up 3.5 percent.
Traders often look to close out positions to make their books look as healthy as possible at the end of a quarter.
Companies will begin reporting financial results for the first three months of the year next week. Earnings for companies in the S&P 500 index are expected to be down 3 percent overall, according to S&P Capital IQ.
