股指延续震荡盘整

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - The stock indices continued to fluctuate and consolidate. The trading volume of the Shanghai, Shenzhen, and Beijing stock markets was 282.62 billion yuan, a decrease of 5.53 billion yuan from the previous day. After a significant upward movement, the stock indices need time to consolidate technically. However, the trading volume in the stock market remains at a relatively high level, and the buying amount of margin trading funds also stays high, indicating that the market sentiment is still relatively optimistic. With the unchanged positive policy expectations and the trend of capital inflow, and the stock indices having broken through the upper limit of the previous consolidation range, the stock indices are likely to remain relatively strong in the future. In general, it is expected that the stock indices will fluctuate with a slight upward trend in the short term. For options, as the current position PCR and implied volatility have both increased, a bull spread strategy can be considered [4]. 3.
