Stocks are drifting higher following mixed reports about the U.S. job market and profits at two of Wall Street’s most influential stocks. The S&P 500 was up 0.5% Friday and heading for its first gain in four days. The Dow was up 201 points, or 0.6%, and the Nasdaq composite was up 0.5%. Treasury yields dipped after the government said hiring was a touch weaker last month than expected. That could help keep pressure off high inflation. Amazon jumped after reporting a much bigger profit than expected. Apple fell after reporting revenue that just barely topped forecasts.
