1. Report Industry Investment Rating - No relevant content provided 2. Core Viewpoints of the Report - Today, all stock indices fluctuated and slightly declined. The total trading volume of the Shanghai, Shenzhen, and Beijing stock markets throughout the day was 1.92 trillion yuan, a decrease of 134 billion yuan compared to the previous day. The Political Bureau meeting pointed out that in 2026, a more proactive fiscal policy and a moderately loose monetary policy will continue to be implemented. The expectation of policy benefits continues to ferment, driving up the market's risk appetite. However, near the end of the year, the power of capital to drive the market to break through is insufficient, and there is still a need for short - term shock consolidation. Currently, the stock indices remain within the previous shock range. Subsequently, as more policy details are introduced at the Central Economic Work Conference, the expectation of policy benefits will gradually become the main line of the market, and the capital inflow is expected to continue, driving the stock indices to have a spring market. In general, the expectation of policy benefits is gradually fermenting, and the stock indices will be mainly fluctuating strongly in the short term. [3] - Regarding options, considering the long - term upward trend of the stock indices, a bull spread or ratio spread with a moderately bullish approach can be adopted. [3] 3.
