The Dow edged up four points to 16,450 as of 12 p.m. Eastern time Friday. The blue-chip index had its worst day in five weeks in the prior session, when Wal-Mart reported lower earnings and economic news was mixed.
The Standard & Poor's 500 index was up less than a point to 1,871 Friday. The Nasdaq fell nine points to 4,060.
Verizon Communications rose the most of the 30 big companies in the Dow. Verizon gained $1.27, or 3 percent, to $49.23 after Warren Buffett's Berkshire Hathaway revealed it had a new investment in the telecom company.
Bond prices fell, pushing up the yield on the Treasury's 10-year note to 2.50
