NEW YORK (AP) -- Stock prices are moving lower as several big companies report financial results that disappointed investors.
The Dow Jones industrial average was off 67 points at 14,551 at midday Thursday, a decline of 0.5 percent. The Dow lost 138 points the day before and is down 2 percent for the week.
The Standard & Poor's 500 index fell five points, or 0.3 percent, to 1,547. The Nasdaq composite fell 21 points, or 0.6 percent, to 3,183.
Ebay sank 5 percent to $53.38 after cutting its profit forecast.
UnitedHealth, the nation's largest health insurance company, was down 3.5 percent at $59.87 after reporting a 14 percent drop in first-quarter earnings.
Weak economic reports also discouraged investors. Unemployment claims rose last week and manufacturing weakened in the mid-Atlantic region.
