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.

1. Report Industry Investment Rating - No relevant content provided 2. Core View of the Report - On December 26, 2025, stock indices oscillated upwards with the total stock market turnover reaching 2160.3 billion yuan, an increase of 216.5 billion yuan from the previous day. The recent increase in trading volume and consecutive rise of stock indices indicate a continuous recovery of market risk appetite. As the new year approaches, positive policy expectations are gradually fermenting. With the appreciation of the RMB, a large amount of relatively high - interest time deposits will mature next year, and their "re - allocation" may bring a large influx of incremental funds into the stock market. The positive policy expectations and the net capital inflow trend together form the medium - and long - term support for stock indices. As the stock indices approach the previous high, short - term attention should be paid to whether they can break through the technical resistance of the previous high. In general, the bullish factors are continuously fermenting, and the stock indices are expected to be oscillating strongly in the short term. For options, since the current position PCR and implied volatility are both in the normal range, a bull spread or ratio spread strategy with a mild bullish view can be adopted [3] 3.

1. Report Industry Investment Rating - No relevant information provided 2. Core Viewpoints of the Report - Today, each stock index fluctuated and rose, with CSI 1000 and CSI 500 leading the gains. The total market turnover of the stock market was 192.18 billion yuan, an increase of 2.46 billion yuan from the previous day. In the medium - to - long term, the positive policy expectations and the trend of capital inflows together form the medium - to - long - term support for the stock index. Currently, positive policy expectations are gradually fermenting. With the appreciation of the RMB, a large number of relatively high - interest time deposits will mature next year, and their "reallocation" may bring a large amount of incremental funds into the stock market. In the short term, the liquidity of the capital market is tightening near the end of the year, policy incremental signals are not yet clear, and the stock index is approaching its previous high, which may cause short - term disturbances. In general, the stock index will maintain a range - bound oscillation in the short term. For options, the current position PCR and implied volatility are both within the normal range, and a bull spread or ratio spread with a mild bullish view can be adopted [3]. 3.
