Wall Street closed out a choppy week of trading Friday with a late- afternoon stumble that led U. S. stock indexes to a mixed finish. The S& P 500 ended the day just a fraction of a point higher after a burst of selling erased a 0.9% gain. Despite a three- day stretch of losses, the benchmark index still finished higher for the week. Big Tech and energy companies fell while health care and industrial stocks rose.
