Nov 12 (Reuters) - U.S. stocks were lower on Thursday as a fall in commodity prices weighed on energy and materials stocks and investors studied comments by several Federal Reserve policymakers for clues on a widely-expected interest rate hike next month.
The selloff was broad based, with all 10 major S&P sectors in the red, and pushed the Dow and S&P 500 below their 200-day moving averages.
Crude oil prices hit 2-1/2 month lows, while copper and other metal prices tumbled to more than six-year lows, weighed down by a strong dollar, weak Chinese data and concerns about oversupply.
Investors are also keeping a watchful eye on whether the Fed will raise interest rates off near-zero levels in December, a possibility Fed Chain Janet Yellen alluded to last week.
Yellen said on Thursday the Fed must weigh impact of the new financial market landscape, but did not comment on the economy or the timing of a rate hike.
Chicago Fed President Charles Evans said the Fed should go slow on raising rates, while St. Louis Fed President James Bullard, who is ready to raise rates, warned of entering an era of permanently low rates.
"You're in a general pullback mode. But I think specifically, what spooked the market is that investors were expecting more dovish comments from Yellen and the other Fed heads," said Adam Sarhan, chief executive of Sarhan Capital in New York.
New York Fed President William Dudley is scheduled to speak at around noon and Fed Vice Chair Stanley Fischer at 6 p.m. ET.

The energy sector sank 1.9 percent as crude oil prices slipped, while the material sector was down 1.5 percent as commodities prices fell.
Chevron and Exxon were down more than 2 percent, weighing the most on the S&P and the Dow.
Retailers were the bright spot after Kohl's reported better-than-expected quarterly net sales, sending its shares up 7 percent at $46.19.
J.C. Penney was up about 3.3 percent. Nordstrom , which was up 2.2 percent, is scheduled to report results after the close.
Cisco, also set to report after the bell, was up 0.7 percent and was among the biggest boost to all three indexes.
Advanced Auto Parts dropped 12 percent to $171.37 after it reported quarterly profit below estimates.
PayPal's shares slid 3 percent to $35.27 after the Wall Street Journal reported Apple was in talks with U.S. banks to develop a rival payment service. Apple was flat.
