On April 4th, U.S. stock markets encountered a significant downturn, with the three primary indexes experiencing considerable drops. The Dow Jones Industrial Average registered a preliminary decline of approximately 1700 points, reflecting a substantial shift in market sentiment. Concurrently, the S&P 500 Index decreased by 4.8%, while the Nasdaq Composite suffered a nearly 6% fall. This decline was largely driven by a sharp reduction in technology stocks, where premium players like Apple (AAPL.O) witnessed a staggering 9% drop, resulting in an estimated loss of around $300 billion in market capitalization. Other notable declines included Amazon (AMZN.O) and Nvidia (NVDA.O), which fell by 8.9% and 7.8%, respectively. Interestingly, Intel (INTC.O) defied the broader market trend with a 2% increase. In international markets, the Nasdaq Golden Dragon China Index also declined by 1.9%.
