Wall Street notched more record highs on Friday, ending the week on a strong note after opening it with a stumble. The S&P 500 rose 1%. It was the fourth straight gain for the index following a sell-off Monday brought on by a flare-up in worries about an upturn in coronavirus infections, particularly those of the more contagious delta variant. Investors are monitoring the latest round of corporate earnings for a clearer picture of how companies are faring as people try to get back to pre-pandemic life. The yield on the 10-year Treasury note rose to 1.28%.
