Stocks fell Wednesday, declining after a two-session rally, amid weakness in banks, concerns about Toyota's massive vehicle recall, and questions about the outlook for the U.S. labor market. Moreover, a rally in the U.S. dollar hurt dollar-traded commodity stocks. Investors considered two employment reports that showed a mixed picture ahead of Friday's report on January jobs from the government. Payroll-services firm ADP reported that private-sector employers cut 22,000 jobs in January following a loss of 61,000 jobs in December. Outplacement firm Challenger, Gray, & Christmas reported that announced layoffs in January rose to a five-month high near 71,500 from just above 45,000 in December. In other U.S. economic news, the Institute for Supply Management (ISM) said its service-sector index rose slightly to 50.5 in January from 49.8 the previous month. A reading above 50 signifies expansion of the massive U.S. service sector, while a reading below 50 indicates contraction. The U.S. dollar gained versus the euro and the yen.
