US stock markets saw a slight increase in the S&P 500 index, primarily driven by gains in semiconductor shares influenced by artificial intelligence developments. This positive momentum came despite ongoing inflation concerns fueled by rising crude oil prices and stalled diplomatic talks between the US and Iran. Strong corporate earnings also supported market sentiment, with more than 80% of S&P 500 companies exceeding earnings estimates. Investors are now closely watching upcoming US inflation data and key macroeconomic indicators for further market direction. These developments are relevant for Indian investors given the interconnectedness of global markets and the impact of inflation trends on economic policies.
