[U.S. Stocks Open High but Close Lower as Momentum Quickly Fades; Rate Cut Concerns and Risk Aversion Cloud the Market] Jin10 News, November 21 — U.S. stock analyst Hannah Erin Lang stated that major indices in the U.S. stock market slipped into the red after opening sharply higher, with the loss of momentum attributed to the following reasons: ① The boost from artificial intelligence appears to be short-lived. Although Nvidia (NVDA.O)'s earnings report seemed to restore some confidence in AI-related trades, this confidence boost may only be temporary. The Information Technology sector led the decline in the S&P 500 index today. ② The market is currently not only worried about an AI bubble but also has other concerns—such as doubts over whether the Federal Reserve will opt for a rate cut in December—which continue to cloud the market. ③ Risk aversion remains prevalent. On Thursday, Bitcoin prices continued their weeks-long decline, while high-momentum stocks like Robinhood (HOOD.O) and Western Digital (WDC.O) also joined the ranks of leading decliners.
