Stocks had another volatile day, in one of the most volatile weeks in a long time. After a big gap down to start the day as global purchasing manager index data came in weak, a better than expected U.S. ISM Manufacturing report caused the market to rip higher, gaining some 15 S&P points in about an hour. In the end the S&P 500 added 0.23% and the NASDAQ 0.3%. In this hectic week that began with a major selloff, the indexes actually both gained ~0.2% when it was all said and done.The pace of growth in the U.S. manufacturing sector edged up to 54.2 from 53.1 in January, exceeding forecasts for a pullback to 52.5. A reading above 50 signals expansion in manufacturing.There was also a huge drop in personal incomes reported pre-market but part of that was due to the payroll tax holiday ending on December 31st.
