Wall Street mixed as investors offload Nvidia and other AI-linked stocks

U.S. equities showed a mixed pattern: while the S&P 500 edged up 0.24%, the Nasdaq Composite slipped 0.17% as investors pulled back from high-flying AI stocks. A key move was SoftBank Group selling its entire stake (~US$5.8 billion) in NVIDIA Corporation, triggering a 2.3% drop in the stock. Despite broader market optimism over the U.S. shutdown, valuation concerns in the AI sector weighed on sentiment.
