市场缩量调整，聚焦攻防均衡丨周度量化观察

Market Overview - This week, the A-share market experienced a comprehensive pullback, with the Shanghai Composite Index down by 1.27%, the CSI 300 down by 1.33%, and the ChiNext Index down by 3.28%. The average daily trading volume in the Shanghai and Shenzhen markets significantly decreased to around 2.3 trillion yuan [2][11][15]. - In the bond market, the overall performance was strong, supported by a stable funding environment maintained by the central bank. The January PMI data fell below the growth line, which is favorable for the bond market [3][31]. Equity Market - The decline in A-shares was primarily driven by a shift in expectations regarding the Federal Reserve's policy, which triggered a significant pullback in precious metals and led to profit-taking in popular sectors ahead of the Spring Festival. The nomination of hawkish candidate Waller as Fed Chair strengthened the dollar, suppressing risk appetite and dragging down cyclical stocks [6][9]. - The investment strategy emphasizes a balanced approach, advocating for low buying and avoiding high chasing. Long-term trends in sectors such as defense, resources, finance, and supply chains are highlighted as areas of potential growth [6][9]. Bond Market - The market is expected to remain volatile in the short term, with favorable factors including the central bank's support for the funding environment. However, the anticipated supply of government bonds poses a challenge. The recommendation is to focus on medium to short-term bond strategies rather than excessive speculation on long-term bonds [7][31]. Commodity Market - The gold market experienced significant volatility, with COMEX gold prices dropping sharply by 8.92% due to a combination of factors, including hawkish expectations from the Fed, profit-taking by bulls, and a sharp decline in silver prices [4][36]. - The short-term outlook for gold suggests potential fluctuations within the current range, with a focus on upcoming U.S. non-farm payroll data and Fed officials' statements. Long-term gold investment remains solid as a core asset [8][40]. Overseas Market - The U.S. economy remains strong, with favorable credit cycle expectations. However, the market is at a relatively high level, and factors such as unclear policy outlooks and declining risk appetite may lead to increased volatility. The AI industry trend is still ongoing, and traditional cycles are expected to recover [9][39].
