NEW YORK, May 13 (Reuters) - U.S. stocks fell on Thursday as downbeat comments on the economy from tech company Cisco Systems Inc <CSCO.O> and retail chain Kohl's Corp <KSS.N> cast doubt on the strength of the U.S. recovery.
Cisco's warnings about a still weak labor market and Kohl's saying it was unconvinced a recovery was at hand underscored the downbeat mood among investors alreadly rattled by fears of sovereign debt defaults in the euro zone. Cisco shares fell 4.5 percent to $25.53 and Kohl's lost 5.8 percent to $53.81.
In addition, a report showed the number of U.S. workers filing for jobless benefits fell only slightly last week, which failed to back up sharply improving monthly payrolls data and suggested the unemployment rate will remain high. [
]Tom Alexander, head of Alexander Trading in Savannah, Georgia, said retail stocks are highly leveraged to a recovery and sensitive to suggestions of economic weakness.
"That's going to be an area of the economy that's always brought into question if they start questioning the recovery," he said.
The Dow Jones industrial average <
> dropped 113.96 points, or 1.05 percent, to 10,782.95. The Standard & Poor's 500 Index <.SPX> fell 14.23 points, or 1.21 percent, to 1,157.44. The Nasdaq Composite Index < > lost 30.66 points, or 1.26 percent, to 2,394.36.1186.69 on Friday April 30 vs 1110.88 close on Friday May 7th through close on Wed. May 12th - 1171.67
The S&P 500 gained 5.47 percent in the first three days of the week -- its biggest three-day run since July 2009. That was after last week's drop of 6.4 percent.
The S&P retail index <.RLX> fell 3 percent. Investors were cautious ahead of April retail sales data on Friday following last week's poor same-store sales data for the same month.
Home builders' shares also fell sharply on concerns over the sector's prospects now that a government tax credit for home buyers has expired. KB Home <KBH.N> was the biggest decliner, falling 6.8 percent to $16.53. The Dow Jones index of home builders' shares <.DJUSHB> fell 4 percent.
Helping to limit the Dow's decline was U.S. aluminum producer Alcoa Inc <AA.N>, whose stock rose 2.7 percent to $12.80 on expectations the metal's price could rise if higher Chinese electricity prices cut the global supply of aluminum. Century Aluminum <CENX.O> rose 5.1 percent to $12.69. [
]Tech stocks stayed in focus after German software company SAP AG <SAPG.DE><SAP.N> agreed to buy smaller U.S. rival Sybase Inc <SY.N> for $5.8 billion. Sybase jumped 14.4 percent to $64.22, while the U.S.-listed shares of SAP fell 0.8 percent to $44.54.
"This M&A activity is encouraging because it's being done on the merit of the deal, not simply because they have excess borrowing power," said Rob Stein, managing partner of Astor Asset Management in Chicago.
On the earnings front, Whole Foods Market Inc <WFMI.O> jumped 5.6 percent to $42.50, boosting consumer stocks after its quarterly profit topped estimates and it raised its full-year forecasts.[
]U.S.-listed shares of Sony Corp <SNE.N> fell 5.1 percent to $31.53 after it forecast a full-year operating profit that was below expectations. [
