Wal-Mart tumbles, Best Buy higher after results

U.S. stocks edged higher on Thursday as an improving economic picture and greater clarity on Federal Reserve policy allowed the market's postelection uptrend to continue, although the Dow Jones Industrial Average was pressured by a selloff in Wal-Mart.

In testimony prepared for her appearance before the Joint Economic Committee, Federal Reserve Chairwoman Janet Yellen said an interest-rate hike could come "relatively soon (http://www.marketwatch.com/story/yellen-says-fed-may-hike-interest-rates-relatively-soon-2016-11-17)," further underlining expectations a rate move could come at the central bank's December meeting. While that has long been seen as a likely time for a rate increase announcement, some investors have speculated on the possibility of a delay following the unexpected election of , which injected a measure of uncertainty into economic outlooks.

The S&P 500 was up 0.3% to 2,183, a rise of 6 points, while the Nasdaq Composite Index rose 25 points to 5,319, a rise of less than 0.5%. The Dow Jones Industrial Average fell 6 points, or less than 0.1% to 18,864.

The Dow was pressured as shares of Wal-Mart Stores Inc. (WMT) fell 4.1% following weaker-than-expected sales (http://www.marketwatch.com/story/wal-mart-shares-fall-after-revenue-miss-2016-11-17). The blue-chip index broke a seven-session winning streak in its Wednesday session, as a postelection rally for financial stocks hit pause. That rally resumed on Thursday, with the financial sector up more than 1%.

"Recent economic data has suggested the economy is improving and that the Fed is likely to raise rates next month. We think that's the right move given how strong labor markets have been, however, equities don't look cheap based on a number of valuation metrics," said David Carter, chief investment officer at Lenox Wealth Advisors.

Consumer inflation rose at the fastest rate (http://www.marketwatch.com/story/higher-gas-prices-boost-inflation-in-october-cpi-shows-2016-11-17)in six months in October, which could make an interest-rate increase more likely, even though the spikestemmed largely from more expensive gasoline. The Philadelphia Fed (http://www.marketwatch.com/story/philly-fed-index-eases-but-remains-positive-for-fourth-month-2016-11-17)said its manufacturing index eased in November to a reading of 7.6 from 9.7 in October.

The ICE dollar index , which measures the currency against a basket of six rivals, rose 0.1%, extending a rally that took it to a 13-month high on Wednesday.
