金融期权：股指窄幅震荡整理

1. Report Industry Investment Rating - No information provided in the report 2. Core Views - Today, all stock indices fluctuated within a narrow range. The trading volume of the Shanghai, Shenzhen, and Beijing stock markets was 2.1247 trillion yuan, a decrease of 145.4 billion yuan compared to the previous day. As silver stopped falling and rebounded, market sentiment improved, and the stock index's operation logic returned to its fundamental factors. However, due to the approaching holiday, the demand for cash during the holiday and concerns about uncertainties, the willingness of funds to trade was relatively weak, and the trading volume of the stock market remained around 2 trillion yuan. In the medium to long term, the positive policy expectations and the continuous net inflow of incremental funds into the stock market remain unchanged, and the core logic for the medium to long - term upward movement of the stock index is relatively solid. Overall, the risk appetite of the stock market before the holiday is cautious, and the stock index mainly fluctuates within a range [4]. - Regarding options, the implied volatility of at - the - money options has recently rebounded. Since the logic for the medium to long - term upward movement of the stock index is relatively solid, the bull spread strategy is maintained [4]. 3.
