TradingKey - On Friday (July 31) Eastern Time, the three major U.S. stock index futures rose collectively in pre-market trading, with Nasdaq 100 futures leading the gains. Amazon's (AMZN) earnings report strengthened market confidence in AI cloud demand and the earnings resilience of tech stocks, driving a rebound in chip stocks and AI infrastructure plays. However, Apple's (AAPL) sharp post-earnings decline, coupled with a rising U.S. dollar and Treasury yields, continued to limit the further expansion of market risk appetite.
