  1. Report Industry Investment Rating - No information provided in the content 2. Core Viewpoints of the Report - Today, all stock indices fluctuated and rose. The trading volume of the Shanghai, Shenzhen, and Beijing stock markets was 1829.3 billion yuan, an increase of 63.2 billion yuan from the previous day. The current market sentiment remains positive and optimistic, with the stock market trading volume at a relatively high percentile level, and investors' risk appetite continues to recover. However, from a technical perspective, since late June, some stocks have achieved significant gains, and some profit - taking funds may need to take profits, so the stock indices may need a period of consolidation. In general, the stock indices will fluctuate with a slight upward trend in the short term, and attention should be paid to the policy guidance of the Political Bureau meeting. Currently, the implied volatility of options has rebounded. Considering that the stock indices continue to trend upward, investors can continue to hold bull spreads or ratio spreads for a moderate bullish view [4] 3.
