The stock market experienced substantial sell-offs as the Dow dropped over 400 points, reflecting growing anxiety over ongoing trade policy issues and uncertainty surrounding technology stocks. The S&P 500 and Nasdaq also faced significant declines, with several tech giants struggling amid concerns related to tariff impacts and disappointing earnings reports. Investor fears intensified as tariff delays and potential additions to existing tariffs loom, impacting market stability. Analysts note that the current volatility is exacerbated by rising bond yields and economic growth fears, leading to a broad-based drop across major indices.
