U.S. stocks are mostly higher in midday trading after four straight days of losses.

The price of oil fell for the first time in a week Friday. It jumped the day before on worries that conflict in the Middle East would affect the flow of crude from the region.

The Standard & Poor's 500 rose a point to 2,057. The Nasdaq composite rose 13 points, or 0.3 percent, to 4,876.

Oil fell $1.36 to $50.06 a barrel in New York.

Cruise operator Carnival jumped 6 percent after reporting income that was higher than analysts were expecting.

Bond prices rose. The yield on the 10-year Treasury note fell to 1.97 percent.
