Stocks just had their worst week of the new year.
The Standard & Poor's 500 ended a shortened trading week down 0.7 percent. Though modest compared to the scary drops last year, it's the worst since the week ended Dec. 16, 2011.
Stock trading will be closed for the Good Friday holiday.
Investors sold stocks Thursday on fears that Spain may have trouble paying back its debt after a key interest rate on Spanish government bonds rose to the highest point since November.
"The firewall that Europe has established is in no way adequate to handle a Spanish default," said Jim Russell, chief equity strategist at U.S. Bank Wealth Management. "We're hopeful that (its debt) will be manageable, but we're not sure."
The Dow and S&P fell right after the opening bell, then turned up briefly before dropping again.
The selling appeared to be tempered by a Labor Department report early Thursday that the number of people seeking jobless benefits fell to a four-year low.
The selling came after the Dow had dropped nearly 125 points a day earlier, its worst decline in a month. That was triggered by minutes from the Federal Reserve's last meeting suggesting that the central bank didn't plan any more steps to push interest rates lower.
"The sell-off yesterday was a little overdone, a reaction to how far we came for the quarter, and how fast," said Brian Lazorishak, a portfolio manager at Chase Investment Counsel. For the first three months of the year, the three major indexes were up 8 percent or more, the best start to a year since the great bull market of the 1990s.
Spain has become the latest point of concern in Europe's debt crisis. Investors are concerned over the ability of the country's government to push through cost-cutting programs at a time when its economy appears to be heading for another recession.
Yields on 10-year Spanish bonds rose 0.08 percentage point to 5.74 percent, the highest level since November and a sign that investors are less confident in the country's finances.
The fear among investors is that if Spain's borrowing costs climb too high, the country will have to follow Greece, Portugal and Ireland and seek outside help to pay its bills. Those three countries got bailouts after their borrowing rates rose above 7 percent.
Worries over Europe drove the dollar to a three-week high against the euro. The euro is trading at $1.31. It was worth $1.33 on March 30.
Seven of the ten industry sectors in the S&P 500 index fell Thursday. Telecommunications companies dropped the most, 1.6 percent. Consumer discretionary companies rose 0.7 percent.
In U.S. stocks, Constellation Brands, a New York-based wine and spirits company, plunged 13 percent, the most in the S&P 500. The company's forecast for 2013 earnings was well below what analysts were expecting. Constellation's brands include Robert Mondavi wines and Corona Extra beer.
Bed Bath & Beyond jumped nearly 9 percent, the most in the S&P 500, after the retailer reported a 25 percent surge in fourth-quarter profit, far more than analysts were forecasting. Sales at stores open for at least a year rose 6.8 percent, well above Wall Street's estimate of 3.8 percent.
More stocks fell than rose on the New York Stock Exchange. Volume was light at 3.3 billion shares.
Gold closed up $16 to $1,630 per troy ounce, recovering from a big loss the day before. Gold had fallen $58 Wednesday to its lowest level in three months.
