Trading is expected to remain choppy next week, as investors look for greater clarity on the economic recovery and fourth-quarter corporate earnings, experts say. Among the week's key economic events will be a meeting of the Federal Reserve's monetary policymaking body on Tuesday and the release of retail sales numbers for November on Thursday. The market snapped its winning streak last Friday, with the Dow Jones Industrial Average ending lower for the first time in nine weeks. It fell 250 points, or 2.8%, to 8646. Elsewhere, the Nasdaq lost 56 points, or 3.8%, to 1422. The S&P 500 shed 24 points, or 2.6%, to 912. Since October, the Dow is up 19%, the Nasdaq is higher by 28% and the S&P is ahead 14%. For the year, the Dow is still down 15%, the Nasdaq is off 28% and the S&P 500 is behind 13%. "We have come a long way. But there is nothing to justify an up move from here," said Michael Driscoll, a trader at Bear Stearns, adding that people are tired and may have had it for the year. On Tuesday, the Federal Open Market Committee will announce a decision on interest rates. Economists are widely predicting no change in monetary policy. At its last meeting in November, the central bank reduced interest rates to 1.25%, their lowest level in more than 41 years. "I suspect the Federal Reserve will say they understand the recovery is not vigorous, but that hopefully activity will pick up soon," said Michael Moran, an economist at Daiwa Securities. On Thursday, the Commerce Department will report November retail sales numbers. Despite strong returns from the Thanksgiving weekend, the monthly numbers are expected to be weak. The consensus, according to Briefing.com, is forecasting retail sales to increase 0.3% in November after a flat reading in October, when vehicle sales were depressed. But excluding autos, they are predicted to be up only 0.2% in November, following a 0.7% gain in October.
