US stocks on Friday fell a second day, following the biggest annual rally for the S&P 500 in 16 years, as investors weighed comments from Fed officials on stimulus and the economy’s strength. The Dow’s drop on Thursday, the first trading session of the year, snapped a streak of five straight gains. The Dow climbed 27 percent last year for its best performance since 1995. The S&P fluctuated Friday, erasing an earlier loss after Fed chairman Ben Bernanke said the headwinds that have held back the US economy may be abating, leaving the country poised for faster growth. The Federal Open Market Committee meets later this month.
