U.S. stocks faced a tumultuous week due to a global tech outage and a shift away from megacap tech stocks. The Dow Jones, S&P 500, and Nasdaq Composite all experienced significant declines, exacerbated by a software glitch affecting multiple sectors and concerns over potential U.S. export curbs on China. Despite a strong start to the earnings season, with 83% of S&P 500 companies beating expectations, uncertainty loomed large. Investors are also factoring in the implications of an assassination attempt on Donald Trump, which some believe may boost his 2024 presidential campaign. The Federal Reserve's anticipated rate cuts and upcoming economic data releases are also in focus as the market navigates these challenges.
