1. Report Industry Investment Rating There is no information provided in the content about the report's industry investment rating. 2. Core Viewpoints of the Report - In February, the bond market may continue to fluctuate, and the coupon strategy may remain a relatively prudent choice. With low credit spreads and the need to control duration risk, investment strategies can focus on the refined exploration of variety spreads, increasing the allocation of low - credit - risk and high - absolute - return varieties [1][2] - Secondary perpetual bonds still have investment value, but their volatility may increase. It is recommended that trading desks control their positions according to their liability - side conditions and try reverse operations [4][5] 3. Summary by Relevant Catalog 3.1 Credit Bonds: Explore Variety Spreads, Pay Attention to Volatility Risks of Secondary Perpetual Bonds 3.1.1 Low Credit Spreads, Focus on Variety Spread Exploration - In January, the long - end interest rate showed a trend of "rapid rise → rapid fall → slow fall", credit bond yields declined, and credit spreads narrowed across the board. Medium - and low - rated bonds outperformed high - rated ones, and medium - and long - term varieties performed better [10][11] - In February, the bond market may continue to fluctuate. For accounts with unstable liability sides, it is not recommended to chase long - term credit. Focusing on medium - and short - term varieties may be relatively advantageous. After the spread compression in January, credit spreads are generally at a low level [14][15] - Investment strategies can focus on three aspects: exploring the spreads of perpetual varieties, seizing the allocation opportunities of brokerage bonds and brokerage sub - bonds, and grasping the "oversold" repair opportunities of science and technology innovation bond component bonds [18] 3.1.2 Secondary Perpetual Bonds Still Have Allocation Value, but Volatility May Increase - In January 2026, bank secondary perpetual bonds had a catch - up rally, with yields declining across the board and credit spreads narrowing, generally outperforming ordinary credit bonds. This rally was mainly driven by funds, while insurance's net buying volume gradually decreased [32][33] - 3 - 5 - year large - bank secondary perpetual bonds still have certain allocation value for accounts with stable liability sides. However, with the rapid entry of trading - desk funds such as funds and the reduction of insurance's buying volume, the volatility of secondary perpetual bonds may increase [39] 3.2 Urban Investment Bonds: Net Financing Increased Year - on - Year, Medium - and Long - Term Transaction Activity Rose - In January, the net financing of urban investment bonds was positive and increased year - on - year. The issuance proportion of medium - and long - term urban investment bonds increased, and the weighted average issuance interest rate decreased across the board [42] - The yields of urban investment bonds declined across the board in January, with medium - and long - term and low - grade varieties performing better. The trading sentiment of urban investment bonds improved, and the medium - and long - term transaction activity increased [48][54] 3.3 Industrial Bonds: Short - End Issuance Proportion Increased, Medium - and Long - Term Secondary Performance was Superior - In January, the issuance and net financing scale of industrial bonds increased year - on - year. The short - term issuance proportion of industrial bonds continued to rise, and the issuance interest rate generally declined [57] - The yields of industrial bonds declined across the board in January, with medium - and long - term varieties showing obvious repair. Most industries' public offering bond yields declined, and medium - and long - term varieties performed better [59][62] 3.4 Bank Secondary Perpetual Bonds: Transaction Sentiment Warmed Up, Medium - and Long - Term Varieties Significantly Repaired - In January 2026, there were no new bank secondary perpetual bond issuances, and the net financing was - 415 billion yuan, a year - on - year decrease of 36.1 billion yuan [65] - The yields of bank secondary perpetual bonds declined across the board in January, with medium - and long - term varieties significantly repaired. The trading sentiment of bank secondary perpetual bonds warmed up, and the transaction of city commercial bank secondary perpetual bonds spread to medium - and low - grade bonds [71][74]

Group 1 - The core view of the report indicates that the credit style simulated portfolio has mostly rebounded, while the interest rate style portfolio continues to decline, with specific strategies showing varying performance [3][15][18] - The weekly return of the credit style portfolio has seen a slight increase in certain strategies, such as the broker debt and secondary debt duration strategies, achieving returns of 0.05% and 0.04% respectively [3][15] - The report highlights that the secondary capital bond heavy strategy has stabilized, with an average weekly return of 0.01%, outperforming the corresponding interest rate style portfolio by approximately 19 basis points [3][18] Group 2 - In terms of return sources, the long-duration portfolio's coupon rates have generally rebounded, indicating the emergence of left-side opportunities, with annualized returns for urban investment and industrial long-duration strategies reaching 2.45% and 2.48% respectively [4][29] - The report notes that the secondary debt duration strategy has shown superior cumulative excess returns over the past four weeks, with returns of 8.1 basis points, outperforming other strategies [5][34] - The short-end configuration value has also increased, with the urban investment short-end sinking strategy recovering nearly 13 basis points from its lowest point in 2025 [4][29]

Group 1: Investment Ratings - No information provided on the report's industry investment rating Group 2: Core Views - As of December 12, controlling drawdown is the main strategic goal recently. In a market with slow rises and sharp falls in the past month, the focus is on drawdown control rather than achieving excess returns through duration + band operations [2][12] - Last week (December 8 - December 12), bond - type ETFs had a net inflow of 2.95 billion yuan, with credit - bond ETFs having a net inflow of 5.37 billion yuan, while interest - rate bond ETFs and convertible - bond ETFs had net outflows of 960 million yuan and 1.46 billion yuan respectively. Bond ETF net values are marginally recovering [3][16] - As of December 15, 2025, compared with the previous week, more than half of the non - financial and non - real - estate industrial bonds saw their yields rise, real - estate bond yields generally increased, and financial bond yields showed differentiation among bond types [4][18] - The trading preference for ultra - long - term credit bonds has not improved. The number of transactions of general credit bonds with a maturity of over 7 years remains at a low level, and the lack of spread protection space weakens investors' motivation [5][20] - In terms of the issuance pricing of local government bonds, the average issuance rate of 10 - year local bonds in the latest week was 2.05%, slightly up from the previous week. The average coupon rates of new 20 - year and 30 - year local bonds were above 2.45%, at a relatively high level within the year. The long - end spreads remain high [6][23] Group 3: Summary of Each Section Quantitative Credit Strategy - As of December 12, the cumulative excess returns of the short - end sinking strategy for urban investment bonds, the bullet strategy for commercial financial bonds, and the sinking strategy for securities firm bonds reached 5bp, 4.4bp, and 1.5bp respectively, while those of other medium - and long - term strategies were less than 5bp. The cumulative excess return of the urban investment dumbbell portfolio, which performed well in the previous two months, dropped to a low of - 25.7bp in the past four weeks. The sinking strategy of the financial bond heavy - position portfolio outperformed the corresponding duration strategy by more than 12bp in cumulative returns [2][12] ETF Strategy - Last week (December 8 - December 12), bond - type ETFs had a net inflow of 2.95 billion yuan. Credit - bond ETFs, interest - rate bond ETFs, and convertible - bond ETFs had net inflows of 5.37 billion yuan, net outflows of 960 million yuan, and net outflows of 1.46 billion yuan respectively. Compared with the previous week, their cumulative unit net value weekly growth rates were + 0.05%, + 0.08%, and + 0.20% respectively [3][16] Coupon Asset Heat Map - As of December 15, 2025, compared with the previous week, more than half of the non - financial and non - real - estate industrial bonds saw their yields rise. Except for private - placement bonds of private enterprises within 1 year, the yield adjustments of other varieties were less than 4BP. Real - estate bond yields generally increased, with the yields of non - perpetual bonds within 1 year rising by more than 5BP. Financial bond yields showed differentiation among bond types, with the yields of commercial financial bonds within 3 years mainly rising, bank sub - debt valuations generally recovering, and the performance of securities firm sub - debt being better than that of ordinary bonds [4][18] Ultra - long Credit Bond Tracking - The trading preference for ultra - long - term credit bonds has not improved. This week (December 8 - December 12, 2025), the number of transactions of general credit bonds with a maturity of over 7 years remained at a relatively low level of around 300. The spread between the most actively traded 7 - 10 - year industrial bonds and 20 - 30 - year treasury bonds is only 19.9bp, which further weakens investors' motivation [5][20] Local Government Bond Supply and Trading Tracking - In the latest week, the average issuance rate of 10 - year local bonds was 2.05%, slightly up from the previous week. The average coupon rates of new 20 - year and 30 - year local bonds were above 2.45%, at a relatively high level within the year. The long - end spreads of local government bonds remain high, with the average spread of bonds with a maturity of 10 years and above being higher than 20bp [6][23]

The short-duration combinations demonstrated strong volatility resistance [2][17] Group 2 - The coupon income from municipal heavy strategies has dropped to a low point, making it difficult to cover weekly capital gains losses. Most municipal heavy combinations have seen their annualized coupon income fall below 1.9% [3][24] - The coupon contributions from the credit style combinations have generally turned negative, particularly for the municipal dumbbell and secondary debt duration strategies, which fell into the -35% to -30% range [3][24] Group 3 - In the past four weeks, broker debt strategies have gained favor, with cumulative excess returns for broker debt duration, municipal dumbbell, and broker debt sinking strategies at 18.5bp, 15.6bp, and 12.4bp respectively [4][28] - The broker debt duration strategy has achieved a cumulative return of 1.92% since the second quarter, ranking just below the municipal dumbbell strategy, which is around 1.98% [4][28] - Short-duration strategies have outperformed the mid-to-long-term benchmarks, with the municipal short-end sinking strategy exceeding the mid-to-long-term benchmark by the largest margin since May [4][30]

Report Industry Investment Rating - Not provided in the content Core Viewpoints - Despite the recent market fluctuations caused by quarter - end liquidity, the medium - to long - term allocation value of credit bonds remains intact. High - grade, long - duration credit bonds show strong resilience, and the narrowing decline in wealth management scale indicates stabilizing market sentiment. The supply - demand pattern of the credit bond market is relatively stable, and the yield - mining potential of credit bonds is prominent. The core logic of credit spread compression still holds, and investors are advised to focus on medium - to high - grade urban investment bonds and industrial bonds in stable industries [2][15] Summary by Directory 1. Credit Bond Configuration Value Unchanged by Quarter - End Disturbance - High - grade, long - term credit bond varieties have significant gains. From March 24th to 28th, the total full - price index of national bonds rose 0.25%, outperforming credit bonds (0.11%) and financial bonds (0.09%). Among them, the full - price index of national bonds over 10 years rose 0.72%, and the index of AAA credit bonds over 10 years rose 1.02% [16] - The scale of wealth management products decreased seasonally, but the decline was narrower year - on - year. In the 13th week of 2025, the scale change was - 0.49 trillion yuan, smaller than - 1.41 trillion yuan in 2024 and - 1.10 trillion yuan in 2023 [19] 2. Market Trading Structure and Selling Pressure - At the end of the month, the selling pressure was relieved. The proportion of GVN in interest - rate bonds dropped from 61.35% on March 17th to 32.96% on March 26th, and then rebounded to 48.54% on March 27th. The proportion of GVN in credit bonds was relatively stable, falling from 39.90% on March 17th to 19.20% on March 20th and rising to 31.48% on March 28th [24] 3. Coupon Advantage of Bonds - Brokerage bonds and insurance bonds have relative coupon advantages. This week, short - end bond yields generally declined. For example, the yields of 1 - month urban investment bonds and medium - short - term notes decreased by 3 bp and 1 bp to 1.97% and 2.01% respectively, and the yield of secondary capital bonds decreased significantly by 9 bp to 1.92% [27] 4. Credit Spread Compression Logic - The core logic supporting credit spread compression still holds. Against the backdrop of the "asset shortage", credit bonds are an important choice for capital allocation. The debt resolution work has reduced the credit risk of urban investment platforms. In the second quarter, the supply pressure of credit bonds eases, and the allocation demand is expected to pick up. 3 - year AA+ urban investment bonds are more cost - effective, and for industrial bonds, defensive industries such as public utilities and transportation are recommended [45] 5. Institutional Behavior and Allocation Strategies - Funds and money market funds have continuously increased their holdings in the past two weeks, and insurance companies have allocated long - end local government bonds. Funds have net - bought 305.42 billion yuan in 1 - year credit bonds, 210.95 billion yuan in 3 - year credit bonds, and 143.82 billion yuan in 5 - year credit bonds. Insurance companies have net - bought 275.69 billion yuan in 20 - 30 - year local government bonds and 22.79 billion yuan in 7 - 10 - year credit bonds. Money market funds have net - bought 2470.26 billion yuan in inter - bank certificates of deposit [39] - It is recommended that investors deploy along three main lines: seize the interest - rate elasticity of 3 - year AA+ urban investment bonds, explore mis - valued opportunities in non - bank varieties such as brokerage subordinated bonds and insurance capital bonds, and pay attention to the net - value restoration opportunities of wealth management subsidiaries' products with a low break - even rate. It is necessary to be vigilant about the economic recovery expectation, and the duration strategy should be moderately flexible [9]
