U.S. stocks ended a volatile session with major averages mixed, as declines in technology shares continued after a five-month rally came to a halt last week.
The S&P 500 ended little changed, while the Nasdaq 100 fell for the fifth time in seven days to cap its worst week since March. The tech-heavy index traveled 3% from high to low Friday and is 11% from its Sept. 2 record. The rout comes after a torrid August capped a 58% rally from late March. Apple Inc. has plunged 16% from its 10-day old high, but remains only at the lowest in a month.
