NEW YORK — U.S. stocks are trading lower at mid-day on new pessimism over the Federal Reserve's willingness to employ new measures that would prop up the economy.

The Dow Jones industrial average is down 83 points to 13,090. The Standard & Poor's 500 is down six to 1,407. The Nasdaq composite is down 10 to 3,064.

However, speaking on CNBC Thursdasy, St. Louis Fed president James Bullard said he wasn't sure if a program, such as government-sponsored bond buying, was needed.
