风险偏好持续回升，股指大幅上涨

1. Report Industry Investment Rating - No information provided in the report. 2. Core Viewpoints - On January 6, 2026, all stock indices rose significantly. The trading volume of the Shanghai, Shenzhen, and Beijing stock markets reached 2.8322 trillion yuan, an increase of 265 billion yuan from the previous day. The continuous increase in trading volume after the holiday is mainly due to the return of market liquidity and the rising expectation of policy benefits. The policy emphasizes the construction of a modern industrial system, which drives the significant rise of related industrial chain stocks. The margin trading balance and margin trading amount have both increased, indicating strong willingness of leveraged funds to enter the market and optimistic market sentiment. In the medium to long term, the expectation of policy benefits and the trend of net capital inflow are the main drivers for the upward movement of stock indices. With the implementation of policy benefits in 2026 and continuous net capital inflow, the risk appetite of the stock market will continue to rise. It is expected that the stock indices will fluctuate strongly in the short term. For options, since the current position PCR and implied volatility are within the normal range, a bull spread or ratio spread strategy with a mild bullish view can be adopted [3]. 3.
