Weak data again raises concerns about economic slowdown, US stocks start September with a negative start

New economic data has once again raised concerns about the health of the economy, and the US stock market had a bad start in September, with tech stocks collectively plummeting. The Dow Jones Industrial Average fell more than 650 points at one point, a decline of 1.6%. The S&P 500 index fell more than 2.2%, and the VIX panic index soared 30%. The Nasdaq fell 3.3%, making it the worst day for global stock markets since the August 5th crash. Nvidia (NVDA.O), the darling of artificial intelligence investors for more than a year, fell more than 9%, leading semiconductor stocks to pressure the stock market. Earlier data showed that the final value of the S&P global manufacturing PMI in August in the US had declined, and the August ISM manufacturing index in the US was also lower than economists' expectations. Larry Tentarelli, chief technical strategist for Trend Report, said: "The market seems to be very sensitive to any data at the moment." "We have become a market that is very dependent on data."
