Core Viewpoint - The U.S. stock market is experiencing a correction, primarily driven by concerns over AI bubbles, regulatory policies, and interest rate outlooks, leading to a shift in investor behavior towards undervalued and defensive assets [1] Group 1: Market Reaction - On August 20, major U.S. stock indices continued their downward trend, with the Nasdaq falling by 0.67%, while the S&P 500 also declined, and the Dow Jones showed relative resilience [1] - Investors are moving towards undervalued sectors and defensive assets, indicating a rapid decline in market risk appetite, which has also contributed to a 1% increase in gold prices on COMEX [1] Group 2: Federal Reserve's Stance - The Federal Reserve's July meeting minutes, released on August 20, revealed that most members are more concerned about inflation risks than employment risks, maintaining the benchmark interest rate in the 4.25%-4.50% range [2] - The market interpreted the minutes as hawkish, leading to a significant reduction in expectations for a large rate cut in September, with the probability of a 25 basis point cut remaining high at 81.9% according to CME's FedWatch tool [2] Group 3: Political Pressure on the Federal Reserve - President Trump publicly called for the resignation of Federal Reserve Governor Lisa Cook, citing allegations of mortgage fraud, which is seen as a serious political intervention that could undermine market confidence in U.S. monetary policy [3] - This political noise has increased investor uncertainty regarding policy direction, prompting a shift of funds towards safe-haven assets like gold, while also creating a dual sentiment in the futures market regarding potential policy easing and political uncertainty [3] Group 4: Implications for Gold and Tech Stocks - The current environment suggests that while rate cuts are typically seen as beneficial for stocks, if perceived as a response to increased recession risks, it could negatively impact future earnings and thus be detrimental to tech stocks [4] - Gold prices are currently supported by uncertainties surrounding the Russia-Ukraine negotiations and the Federal Reserve's policy direction, with potential for a pullback if these uncertainties ease [4][5] - For investors, gold serves as a necessary but costly insurance, and while some defensive positioning is reasonable, expectations for excessive returns should be tempered, especially in a market driven by domestic policies and liquidity [5]
