How major US stock indexes fared Friday

Stocks ended a wobbly week broadly lower, with a good part of Friday’s loss attributable to weakness in big technology companies like Apple and Amazon.

The S&P 500 index fell and marked its first weekly loss after three weeks of gains. Small-company stocks continued to badly lag the rest of the market, a signal that investors could be becoming more concerned about how strongly the economy will keep growing in coming months. Treasury yields remained relatively low, another sign of caution among investors.
