Next week's global highlights: The Federal Reserve's most favored inflation indicator will be released, NVIDIA's financial report tests AI trading. Federal Reserve Chairman Powell issued the strongest signal so far this week, indicating that interest rate cuts are imminent, driving risk assets to rise sharply, and the S&P 500 index once again approaches a historic high. Looking ahead to next week, the performance of artificial intelligence (AI) chip manufacturing giant NVIDIA will embark on a new chapter, and the rise of the US stock market will face an important test, as the company's strong performance has injected momentum into the entire market.
