短期内股指震荡整理

1. Report Industry Investment Rating - No relevant content provided. 2. Core Viewpoints - Today, each stock index hit the bottom and rebounded, showing a volatile consolidation throughout the day. The total trading volume of the Shanghai, Shenzhen, and Beijing stock markets was 2.1329 trillion yuan, a decrease of 216.9 billion yuan from the previous day. The policy - favorable expectations brought by the "15th Five - Year Plan" are gradually fermenting, providing strong support for the stock index. However, as it enters November, the incremental expectations of domestic policies are decreasing, and the impact of the easing of external risks is diminishing at the margin. The upward driving force has weakened in the short term. As the valuation of stocks rises, the willingness of profitable funds to take profits has increased, and there is still a need for a short - term technical adjustment of the stock index. In general, under the game between the fermentation rhythm of policy - favorable expectations and the profit - taking rhythm of funds, the stock index will mainly fluctuate and consolidate in the short term. Currently, the implied volatility of options remains relatively stable. Considering the long - term upward trend of the stock index, it is advisable to maintain a bullish spread or covered - call strategy [4]. 3.
