Golden Finance reported that new economic data has once again raised concerns about the health of the economy. The U.S. stock market had a bad start in September, and technology stocks collectively plummeted. The Dow Jones Industrial Average fell more than 650 points, a drop of 1.6%. The S&P 500 fell more than 2.2%, and the fear index VIX soared 30%. The Nasdaq fell 3.3%, the worst day since the global stock market crash on August 5. Nvidia (NVDA.O), the darling of artificial intelligence that has been the focus of investors for more than a year, fell more than 9%, leading semiconductor stocks to put pressure on the stock market. Earlier data showed that the final value of the S&P Global Manufacturing PMI in the United States in August declined, and the U.S. ISM Manufacturing Index in August was also lower than economists' expectations. "The market seems to be very sensitive to any data at the moment," said Larry Tentarelli, chief technical strategist at Blue Chip Trend Report. "We have become a very data-dependent market."
