NEW YORK Stocks declined on Thursday, taking a step back from their recent advance, prompted by comments by the ECB president on the euro and Europe's outlook.
The euro currency dropped against the safe-haven dollar and yen, spurring a retreat from risky assets such as stocks, after European Central Bank President Mario Draghi said the exchange rate was important to growth and price stability. Investors took that as a sign the bank is concerned about the euro's advance and its effect on the region's economy.
Growth sectors were among the weakest performers on the S&P 500: the S&P 500 materials index .SPLRCMA was down 0.6 percent while the S&P energy index .SPNY was down 0.5 percent. Housing stocks also declined, with a housing sector index .HGX off 1.4 percent.
Despite the day's decline and weakness earlier this week, the stock market has been in an almost uninterrupted up trend for most of the year, with the S&P 500 up 5.8 percent so far for 2013.
Many analysts say some weakness at this point is no surprise.
