1. Report Industry Investment Rating No relevant content provided. 2. Core Views of the Report - The Huaxia Securities view is to wait for the bond market to return to fundamental pricing, focus on trading long - term bonds, and the anti - decline of credit bonds may continue under loose funds. The current bond market is weak, with long - term interest rates reversing multiple times during the day. Policy factors, the stock - bond seesaw, and bond fund redemption fee reforms have impacted the bond market. The bullet strategy is theoretically better, and 10Y and 30Y bonds are suitable for intraday trading. There are opportunities in the spread compression of some high - coupon local bonds. Credit bonds are more anti - decline under loose funds [2]. - The seller's view is that the bond market sentiment remains low, and most expect a sideways movement. Currently, 22% of institutions are bullish, 56% are neutral, and 22% are bearish [2]. - The buyer's view is that over 60% of buyers are neutral. Overall, the sentiment of fixed - income buyers is bullish, and the sentiment index has risen. Currently, 20% of institutions are bullish, 68% are neutral, and 12% are bearish [2]. 3. Summary by Relevant Catalogs 3.1 Seller and Buyer Market 3.1.1 Seller Market情绪指数与利率债 - The weighted sentiment index this week is - 0.02, and the unweighted index is 0, both lower than last week.

The overall view of institutions is neutral - bullish, with 5 bullish, 17 neutral, and 3 bearish institutions [11]. 3.1.3 Credit Bonds - Market hot topics include the stock - bond seesaw and public fund fee reforms. The stock - bond seesaw leads to intensified capital diversion from the bond market, increased pressure on bond fund redemptions, and the public fund fee reform triggers a structural adjustment on the liability side, causing a full - scale increase in credit bond yields [16][17]. 3.1.4 Convertible Bonds - This week, institutions generally hold a neutral - bullish view. 40% of institutions are bullish, and 60% are neutral [20]. 3.2 Treasury Bond Futures Tracking 3.2.1 Futures Trading - Futures prices generally declined.
