Most stocks fell Tuesday as some earnings reports disappointed investors, but the Dow rose 20 points, its fifth straight daily gain.
Among the companies posting worse-than-expected results or adjusting their forecasts downward were bond insurer MBIA, engineering firm Fluor and video game maker Electronic Arts.
"The market seems to go back and forth daily based on who reports earnings and what they report, and today you had a couple of modestly disappointing earnings reports," said Dean Gulis, portfolio manager at Loomis Sayles & Co. "To some extent you're having a reaction to a pretty strong day yesterday."
