1. Report Industry Investment Rating The provided content does not mention the industry investment rating. 2. Core Viewpoints of the Report - The stock - bond seesaw effect has generally strengthened since 2025, but there are periods of weakening. The restoration of the stock - bond seesaw effect requires the continuous strengthening of the pricing factors of stocks or bonds. The market trends of the stock and bond markets have their own dominant factors, and the stock - bond seesaw is not the only pricing factor for bonds [3][43][46]. - The bond market strategy is to hold bonds during the holiday and appropriately increase the account's income elasticity. The report is optimistic about the future market and suggests starting to prepare for the whole - year trading market, shifting from a configuration - oriented to a trading - oriented approach [48][52]. - In the first week of February, the bond market strengthened with oscillations due to the weakening of the equity market and the central bank's support. The 30 - 10y spread of treasury bonds has compression potential, and there are opportunities in long - term credit bonds [7][72][77]. 3. Summary by Directory 3.1 Stock - Bond Seesaw "Failure" Re - discussion - **Overall Strengthening of the Stock - Bond Seesaw Effect in 2025**: The strengthening is mainly due to the significant boost in market risk appetite by the strong performance of the equity market and the significant widening of the stock - bond price ratio. For example, from September 2024 to October 2025, the share of open - ended bond funds decreased by 3.18%, while that of open - ended stock funds increased by 22.92%. As of February 2026, the margin trading balance in the Shanghai and Shenzhen stock markets reached 2.67 trillion yuan [10][14][15]. - **Weakening of the Stock - Bond Seesaw Effect in Some Windows**: There are two situations: stock - bond co - rising and stock - bond co - falling. Stock - bond co - rising occurs when the bond market has clear bullish factors (mostly related to easing expectations), and the yield is in a downward channel. Stock - bond co - falling is mostly related to the redemption of "fixed - income +" products. For example, in November 2025 and February 2026, the redemption of "fixed - income +" products led to an increase in bond yields [22][32]. - **End of the Stock - Bond Seesaw "Failure"**: The restoration of the stock - bond seesaw effect is driven by different factors, such as the "anti - involution" logic in July 2025 leading to the bond market following the adjustment, and the early "spring rally" in the equity market and the cooling of the bond market's easing expectations in late December 2025 - early January 2026 [41]. - **Summary**: The "failure" of the stock - bond seesaw is more common after the bond market's cost - performance returns. To restore the seesaw effect, the pricing factors of stocks or bonds need to be continuously strengthened. The subsequent trend of the "failure" during the "fixed - income +" redemption stage after the stock market decline needs to be observed [43][46]. 3.2 Bond Market Strategy - **Under - expected Bond Market Gains after the Decline in Risk Appetite**: The bond market gains were under - expected due to the redemption of "fixed - income +" funds and the lack of a clear trading theme in the short - term bond market [48]. - **Optimistic Outlook for the Future Market**: The central bank's pre - holiday capital injection is relatively active, and the capital fluctuation pressure is controllable. However, the institutions' cross - holiday capital arrangements are relatively late, and short - term frictions in the last week need attention. The power of allocation - type funds is relatively strong, and the pricing influence of the equity market on bonds is weakened. The bond market yield is still in the cost - performance range [52][61][66]. - **Operation Suggestions**: Continue to layout convex - type varieties, conduct spread mining according to the convex points. Focus on 5y China Development Bank bonds in the short - term, 8y Export - Import Bank of China bonds and 10y local government bonds in the medium - term. Insurance funds can configure long - term local government bonds at high yield fluctuations. It is recommended to hold bonds during the holiday and appropriately increase the account's elasticity, and layout long - term offensive varieties with good liquidity [69][72]. 3.3 Interest - Rate Bond Market Review - **Market Performance**: In the first week of February, the equity market was weak, and the bond market strengthened with oscillations. The 10y treasury bond yield was blocked at 1.80% multiple times, and the 30y treasury bond led the rise, driving the compression of the 30 - 10y spread. The 1y treasury bond active bond yield rose 2BP to 1.3100%, the 10y treasury bond active bond yield fell 0.8BP to 1.8020%, and the 30y treasury bond yield fell 3.45BP to 2.2255% [7]. - **Funding Situation**: The central bank's net withdrawal of funds was 656 billion yuan this week, and the funding situation was generally loose. The 1y inter - bank certificate of deposit issuance price of national joint - stock banks fell to 1.58%, and the weighted price of DR007 fell to 1.4613% [8]. - **Primary Issuance**: The net financing of policy - financial bonds decreased, while the net financing of treasury bonds, local government bonds, and inter - bank certificates of deposit increased [92]. - **Benchmark Changes**: The term spreads of treasury bonds and China Development Bank bonds both narrowed. The short - end yields of treasury bonds rose 2.08BP, and the long - end yields fell 0.1BP. The short - end yields of China Development Bank bonds fell 1.32BP, and the long - end yields fell 2.2BP [89].
