Stocks managed to eke out tiny gains after another day of wobbly trading, leaving the S&P 500 higher for the second week in a row.

       The benchmark index made its fourth straight gain. The Dow Jones Industrial Average and the Nasdaq edged higher while small-company stocks fell and Treasury yields dropped. There was little for investors to like in an economic report showing a big drop in consumer confidence last month as the delta variant of COVID-19 spread.

       On Friday:

       The S&P 500 rose 7.17 points, or 0.2%, to 4,468.

       The Dow Jones Industrial Average rose 15.53 points, or less than 0.1%, to 35,515.38.

       The Nasdaq rose 6.64 points, or less than 0.1%, to 14,822.90.

       The Russell 2000 index of smaller companies fell 20.96 points, or 0.9%, to 2,223.11.
