U.S. stocks wavered between small gains and losses Tuesday morning as trading turned choppy after an early slide. Losses in health care, energy and other sectors outweighed gains in banks and industrial companies. The decline in energy stocks came as oil prices fell ahead of an afternoon announcement by the White House on whether the U.S. will pull out of a landmark nuclear deal with Iran.
