US stock futures have surged to new record highs, primarily driven by Nvidia's significant stock increase following reports that the US has approved limited sales of AI chips to China. This surge reflects strong momentum in the semiconductor and technology sectors. Additionally, Cisco Systems, a major player in networking, has upgraded its forecast, further boosting investor confidence. As markets react to these developments, they are also keeping a close eye on ongoing US-China trade negotiations, inflation data, and increasing expectations regarding Federal Reserve interest rate hikes, all of which are influenced by geopolitical tensions and rising oil prices.
