Wall St. suffers biggest drop since September

(Reuters) - Wall Street suffered its worst session in over a month on Thursday as lower commodity prices weighed on energy and materials stocks and comments by a Federal Reserve policymaker hinted at an approaching interest-rate hike.

The rout hit all 10 major S&P sectors and pushed the Dow and S&P 500 below their 200-day moving averages, which some traders believe portends additional declines.

Investors are keeping a watchful eye on whether the Fed in December will raise rates for the first time in nearly a decade, as is widely expected after recent strong jobs data.

In a speech on Thursday, Fed Chair Janet Yellen did not comment on the economy or the timing of a rate hike.

But New York Fed President William Dudley said “it is quite possible that the conditions the Committee has established to begin to normalize monetary policy could soon be satisfied.”

Following rapid gains in October, stock investors still concerned about China’s economy and the effects of a U.S. rate hike have been taking money off the table, said Michael Matousek, head trader at U.S. Global Investors Inc in San Antonio, which manages about $1.3 billion.

“Those are the two things one everyone’s minds,” Matousek said. “That’s why you have some of this selloff.”

The S&P and Dow dipped the most in a day since Sept 28.

The Dow Jones industrial average .DJI fell 1.44 percent to end at 17,448.07, the S&P 500 .SPX lost 1.4 percent to 2,045.97. The Nasdaq Composite .IXIC dropped 1.22 percent to 5,005.08.

The energy sector .SPNY sank 2.4 percent. Chevron CVX.N and Exxon Mobil XOM.N both fell more than 2.5 percent.

The materials sector .SPLRCM lost 2 percent, hurt by a 1.3 percent fall in DuPont DD.N and a 2.5 percent drop in Dow Chemical DOW.N.

Retailers were a bright spot after Kohl's KSS.N reported better-than-expected quarterly net sales, sending its shares up 6.1 percent.

But after the bell, Nordstrom JWN.N reported third-quarter results below its own expectations, blaming softer sales trends, and its shares slumped 16 percent in extended trade.

Cisco CSCO.O fell 4 percent in extended trade after it posted its fiscal first-quarter results.

During the regular trading session, PayPal's shares PYPL.O slid 2.1 percent after the Wall Street Journal reported Apple AAPL.O was in talks with U.S. banks to develop a rival payment service. Apple lost 0.3 percent to $115.72.

Declining issues outnumbered advancing ones on the NYSE by 2,521 to 557. On the Nasdaq, 2,177 issues fell and 629 advanced.

The S&P 500 index showed four new 52-week highs and 19 new lows, while the Nasdaq recorded 34 new highs and 142 new lows.

About 7.1 billion shares changed hands on U.S. exchanges, about the same as the daily average for the past 20 trading days, according to Thomson Reuters data.
