全球资产集体承压：科技股、加密货币与黄金同步下挫，美联储政策迷雾成关键变量

Group 1: Market Overview - The global financial markets experienced a significant downturn on "Black Friday," with both risk and safe-haven assets declining simultaneously, including a more than 3% drop in Nvidia and a four-day decline in Tesla [1] - The cryptocurrency market saw a substantial correction, with Bitcoin briefly falling below $96,000, while gold prices dropped over 2% to below $4,100 per ounce [1] - The decline was attributed to a cooling of interest rate cut expectations from the Federal Reserve, a data vacuum due to the U.S. government shutdown, and concentrated selling pressure in overvalued sectors, leading to increased investor anxiety as indicated by the VIX index rising above 22 [1] Group 2: Technology Sector - Technology stocks, previously a key driver of market gains, faced significant selling pressure, with the Nasdaq 100 futures down 1.5% and the S&P 500 futures down 1% [2] - The adjustment in tech stocks is closely linked to shifting Federal Reserve policy expectations, with the probability of a 25 basis point rate cut in December dropping from 70% to 47% [2] - Nvidia's pre-market drop of 3.11% and a cumulative market cap loss exceeding $200 billion reflect ongoing concerns about high valuations in the AI sector [4] Group 3: Cryptocurrency and Gold - Both cryptocurrencies and gold experienced rare simultaneous declines, indicating a re-evaluation of risk and safe-haven assets [3] - Bitcoin fell to $95,985.4, a nearly 3% drop from the previous close, while Ethereum saw a 10.9% decline, marking its largest single-day drop in three months [5] - Gold's decline of over 2.21% to a low of $4,059.17 per ounce was influenced by a stable U.S. dollar and perceptions of U.S. economic resilience, reducing gold's appeal as a safe-haven asset [5] Group 4: Economic Data and Policy Uncertainty - The U.S. government shutdown has created a data vacuum, delaying the release of critical economic indicators such as the October CPI and employment data, which complicates Federal Reserve policy decisions [6] - The absence of sufficient data may prevent the Fed from cutting rates, contributing to increased market volatility as uncertainty looms [6]
