Wall Street faces pressure today: U.S. stock futures are falling after a massive sell-off in the tech sector, with the S&P 500 and Nasdaq recording their worst declines in over two weeks. Investors are already focusing on retail earnings and the Jackson Hole symposium of the Federal Reserve. The Fed minutes are expected to be released today, which could influence expectations about a possible 25 basis point interest rate cut in September. Additionally, there are concerns about potential government involvement in chip companies benefiting from the CHIPS Act, which increases regulatory uncertainty in the sector.
