Core Viewpoint - The market has shown signs of cooling down after a prolonged period of strength, indicated by a significant drop in major indices, suggesting a potential period of consolidation and correction [2][4]. Group 1: Market Dynamics - A sudden large drop in indices has occurred, breaking through short-term moving averages, indicating a significant sell-off by large funds, which reflects a cooling intention from the market leaders [2]. - The implied volatility of options has surged, reflecting extreme market emotions. During the downturn, this corresponds to a capitulation of bullish positions, while in an uptrend, it indicates a rush of new capital entering the market [3]. - The recent large drop in indices has led to a noticeable shift in market sentiment, with implied volatility showing a negative correlation with index movements, suggesting fear of further declines [4][5]. Group 2: Market Sentiment and Future Outlook - The current market correction is seen as a natural response to previous extreme bullish sentiment, with the potential for a gradual recovery rather than a sharp decline, as existing funds appear to be staying in the market [7]. - The macroeconomic backdrop remains supportive, with expectations of a potential easing in the US dollar and domestic policies aimed at reducing competition, which could provide a foundation for future market strength [7]. - Despite recent declines, smaller indices and thematic stocks have shown relative strength, indicating that not all segments of the market are equally affected [8]. Group 3: Investment Strategies - In light of the current market conditions, a "buy low, sell high" strategy is recommended, with a focus on maintaining a balanced options portfolio to manage risk effectively [9]. - For options traders, it is advised to limit exposure to positive Vega, as the market remains heated, and to consider strategies that mitigate risks associated with extreme downward movements [11]. - Conservative investors may find more stability in indices like the 50 and 300, which are perceived to have lower downside risk compared to more aggressive indices [11].

1. Report Industry Investment Rating No relevant content provided. 2. Report's Core View - On September 3, 2025, all stock indices fluctuated and declined. The total trading volume of the Shanghai, Shenzhen, and Beijing stock markets was 2.3957 trillion yuan, a decrease of 516.7 billion yuan from the previous day. Due to the significant increase in some stocks, the profit - taking demand of profitable funds has risen, and the recent trading volume of the stock market has shrunk, indicating a certain divergence in market expectations, and the stock indices have entered a short - term technical adjustment. In the long - term, the expectation of policy benefits and the loose capital situation strongly support the stock indices, and the logic of the long - term upward movement of the stock indices remains strong. Anti - involution policies and consumption - promotion policies optimize the supply - demand structure from both the supply and demand sides, promote a moderate increase in the price index, and repair corporate profits. In terms of capital, the margin trading balance has risen rapidly, non - bank deposits have soared, and long - term funds have continued to enter the market. The continuous inflow of incremental funds in the stock market promotes the repair of stock valuations. In general, in the short term, the marginal effect of policy benefit expectations has weakened, and the profit - taking demand of profitable funds has increased. The stock indices are expected to fluctuate widely in the short term. Currently, the implied volatility of options continues to rise. Considering the long - term upward trend of the stock indices, investors can continue to hold bull spreads or ratio spreads for a mild bullish view [3]. 3.
