NEW YORK - Stocks closed broadly lower for a third straight week on signs that U.S. consumer demand may be weakening.
The retailers Gap Inc. and Aeropostale Inc. each lost more than 14 percent Friday after cutting their profit forecasts for the year, in part because of higher costs for raw materials and sluggish sales. That was a worrying sign for investors who had counted on shoppers to lead a recovery in spending.
Gap's results pushed down other clothing companies who have been hit hard by the rising price of cotton and by shoppers who are reluctant to splurge. Polo Ralph Lauren Corp. and J.C. Penny Co. each dropped more than 4 percent, while Philadelphia's Urban Outfitters Inc. fell 3 percent.
The Dow Jones industrial average fell 93.28 points, or 0.7 percent, to 12,512.04. The Standard & Poor's 500 index lost 10.33, or 0.8 percent, to 1,333.27. The Nasdaq composite dropped 19.99, or 0.7 percent, to 2,803.32. Each market index fell by more than 0.3 percent for the week. The Nasdaq lost the most, 0.9 percent.
One exception to the retailer gloom was Barnes & Noble Inc. The bookseller jumped nearly 30 percent after announcing late Thursday that Liberty Media Corp. had offered to buy the company for $1 billion in cash.
Stock indexes have been staying within a relatively small range since a May 4 plunge triggered by a sharp drop in oil prices. The Dow fell more than 200 points in two days. After several weeks of waffling, the index is trading slightly above where it was after that two-day fall.
May is traditionally a weak month for the stock market. Traders have little to base buying and selling decisions on, with corporate-earnings season officially over and economic news scarce. Trading has been relatively light.
A stronger U.S. dollar has also hurt stocks. The dollar rose against the euro Friday after the Fitch ratings agency downgraded Greece's debt three notches further into junk status, escalating worries about the European debt crisis.
In recent months, markets have fallen when the dollar rises against the euro because the stronger U.S. currency has signaled that European countries are still struggling to get their debt under control.
"A stronger dollar and a stronger U.S. market can coincide, but not when the U.S. economic data are weak," said Quincy Krosby, chief market strategist for Prudential Financial. "This has been a stronger dollar that has come because of another currency weakening, not a stronger U.S. economy."
Concerns about the strength of the economy pushed government bond prices higher as investors sought out safer assets.
