On Thursday, US stock markets closed with mixed results, as the Nasdaq and S&P 500 both touched intraday record highs but ultimately all three major indices declined collectively, weighed down by tariff measures. Microsoft and Meta Platforms soared on the back of robust earnings reports, bolstering overall market sentiment. President Trump unveiled new tariff measures, which, however, face significant legal hurdles. The Federal Reserve maintained its interest rates unchanged, with Chairman Powell noting that the policy direction for September remains undecided. Other notable market developments included Nvidia's chip security concerns, Tesla's Robotaxi service being halted in California, and earnings releases from several other companies.
