US stocks capped a volatile month on Friday, after the 10-year Treasury yield (^TNX) jumped to its highest level since January 2025 and Big Tech giants reported continued investments in artificial intelligence. The Dow Jones Industrial Average (^DJI) rose 0.5%, while the S&P 500 (^GSPC) also added 0.7%. All three major averages posted gains for the week, and the Dow also recorded a 0.7% gain for the month of July. The latest quarterly results from the "Magnificent Seven" companies showed that Big Tech continues to invest in AI, reassuring tech investors who had grown fearful of a slowdown in AI and higher interest rates. However, the latest check on how Americans are feeling from the University of Michigan showed a broad pickup in sentiment.
