1. Report Industry Investment Rating - No information provided in the content 2. Core Viewpoints of the Report - Today, all stock indices fluctuated within a narrow range. The total trading volume of the Shanghai, Shenzhen, and Beijing stock markets was 2001.0 billion - 2037.0 billion yuan. Due to the approaching holiday, investors' trading willingness was relatively weak. The inflation data for January showed that CPI continued to grow year - on - year, and the year - on - year decline of PPI narrowed. The repair of inflation expectations promoted the repair of corporate profit expectations, and the macro expectations improved. In the long - term, the positive policy expectations and the continuous net inflow of incremental funds into the stock market remained unchanged, and the core logic for the long - term upward movement of stock indices was relatively solid. Overall, the risk appetite of the stock market was cautious before the holiday, and stock indices mainly fluctuated within a range. For options, the implied volatility of at - the - money options has rebounded recently. Given the relatively solid long - term upward logic of stock indices, the bull spread strategy is maintained [4]. 3.
