The US stock market is experiencing mixed movements as investors brace for key earnings reports from Nvidia and ongoing geopolitical concerns, particularly regarding tensions with Iran. The tech sector is under significant pressure, primarily driven by a sell-off in semiconductor stocks, which has negatively impacted the Nasdaq and S&P 500 indexes. Despite easing bond yields, the weakness in chipmakers has overshadowed any potential gains, with the Nasdaq declining nearly 1% and Nvidia extending its losing streak. Analysts are closely watching how these developments will influence market trends in the coming week.
