S&P 500 and VOO ETF: Nvidia earnings and other catalysts for US stocks

The S&P 500 index fell to 7,674 points from its record high of 7,820, driven by ongoing concerns over the US national debt. This week's market focus is on upcoming earnings reports and economic data. Nvidia's earnings report is the primary catalyst, as the company holds the largest index weight and benefits most from the AI boom. Analysts expect revenue to nearly double, with a strong beat potentially lifting AI semiconductor stocks broadly. Other reports include Marvell Technology, following its $12 billion Google deal, and software firms like Salesforce. The Jackson Hole symposium features new Fed Chair Kevin Warsh, while US sanctions on Iran could raise oil prices.
