Report Industry Investment Rating - No relevant content provided Core Viewpoints - Today, all stock indices oscillated and rebounded. The total trading volume of the Shanghai, Shenzhen, and Beijing stock markets was 2.0904 trillion yuan, a decrease of 506.2 billion yuan from the previous day. The volume - shrinking rebound of the stock market reflects that the overall market sentiment remains optimistic, with funds entering the market on dips after corrections, and the downside space for stock indices is limited. At the same time, it also shows that funds chasing higher near the previous high points remain relatively cautious [4]. - In the short term, the tariff war has resurfaced, and external uncertainties have increased before November. Coupled with the current relatively high valuation level, investors' willingness to take profits has risen, and there is short - term technical correction pressure. In the medium to long term, the problem of insufficient effective domestic demand still exists, and the disturbance of external tariff factors still remains. There are strong expectations for policy - makers to stabilize the macro - fundamentals, and the expectation of policy benefits forms strong support for the stock indices. The trend of net capital inflow into the A - share market remains unchanged, so the stock indices have strong medium - to - long - term support. Overall, under the game between profit - taking sentiment and policy support, the stock indices are expected to maintain wide - range oscillations in the short term [4]. - Currently, the implied volatility of options remains relatively stable. Considering the medium - to - long - term upward trend of the stock indices, investors can continue to hold bull spreads or covered calls [4].
