Concerns about AI bubble affect US stock trends, Nvidia faces profit pressure

According to Jinshi News, analyst Adam Button stated that today's performance of the US stock market does not meet the bullish expectations, with many stocks leaving unsightly candlesticks on the charts. He pointed out that there is a bubble in Nvidia, and the performance of Google's Gemini 3 further validates this, indicating that other companies can also create large language models without Nvidia chips, which may reduce Nvidia's profits. Nvidia accounts for 8% of the S&P 500 index, and a halving of its value would directly cut 4 percentage points. In addition, the Federal Reserve's stance also affects the market, as Powell opposes a rate cut in December, and the market's expectations for a rate cut have fallen to 36%.
