Market Gains Persist Despite Sticky Inflation Concerns After Fed Chair’s Jackson Hole Address

Nvidia’s strong earnings performance helped drive the market’s weekly gains. After releasing second-quarter results that exceeded forecasts on both revenue and profit margins, the semiconductor giant saw its shares surge nearly 9% the following day, ending a four-quarter streak of post-earnings declines. The company reported quarterly revenue more than doubling year-over-year and projected 70% growth for fiscal 2028, significantly outperforming the 44% expected by analysts. “This report may delay conversations about aggressive monetary tightening for now, as it suggests revenue momentum remains intact,” said Melissa Brown, global head of investment decision research at SimCorp. However, she cautioned about growing market concentration risks, noting that artificial intelligence-related stocks are increasingly diverging from broader market trends. “We’re seeing unusually low stock correlations, which complicates market risk assessments. This level of concentration creates significant volatility exposure for investors holding just a handful of names,” Brown observed.
