The stock market was up recently because of a combination of factors including robust earnings reports from several companies, especially in the artificial intelligence and technology sectors, and positive economic data. The S&P 500 and Dow Jones both hit new record highs supported by strong demand for AI- related products and upbeat forecasts from companies like Ulta Beauty. Additionally, an upward revision in second-quarter GDP also contributed to optimism. However, despite Nvidia's slight earnings miss in one area, the overall sentiment remained positive, particularly due to ongoing strong demand for AI chips and positive guidance from other tech firms. Investors are also looking ahead to upcoming inflation data which could influence future market moves, but for now, optimism about AI growth and solid earnings pushed the market higher.
