Group 1: Investment Rating - The report does not provide an overall investment rating for the bond industry. Group 2: Core Views - Market fluctuations have caused some disturbances to the liability side, but overall liability side stability remains acceptable. ETFs and "fixed income +" funds have seen small net outflows, but the pace has slowed compared to early September, and insurance funds still focus on allocation. [3][8] - In a volatile market, the operating strategies of public - offering institutions have diverged. Low - volatility strategy funds aiming for absolute returns may have reduced their allocations to high - price bonds and convertible bonds in general, while high - volatility tolerance products and relative return funds can increase allocations to some convertible bond issues with sufficient corrections and fundamental support. [3][9] - Different - priced convertible bonds have different performances and strategies. High - price convertible bonds have proven their upward logic, and for high - tolerance funds, holding is better than trading. Medium - price convertible bonds are the core of the "attack - and - defense" strategy, and bonds with reasonable price structures and catalytic expectations should be selected. The valuation of low - price (partial - debt) convertible bonds has reached an extreme level, and caution should be exercised. [2][3][9] - In October, investors are advised to pay attention to Shangyin Convertible Bond, Shouhua Convertible Bond, Jingke Convertible Bond, Kangtai Convertible Bond 2, Baolong Convertible Bond, Keshun Convertible Bond, Yingbo Convertible Bond, Huaya Convertible Bond, Wankai Convertible Bond, and Luwei Convertible Bond. [3][13] Group 3: Summary by Directory 1. Convertible Bond Weekly Thinking - The convertible bond market has shown limited adjustments and slight recoveries. In the past week, the ChinaBond Convertible Bond Index rose by about 1 percentage point, and the 100 - yuan premium rate also slightly recovered. [8] - The liability side of convertible bonds remains stable. Although there are small net outflows from some funds, the overall situation is improving, and insurance funds still focus on long - term allocation. [3][8] - Public - offering institutions' strategies have diverged. Low - volatility funds reduce positions, while high - volatility tolerance funds increase positions in some high - quality bonds. [3][9] - Different - priced convertible bonds have different characteristics and strategies. High - price bonds are suitable for holding, medium - price bonds need comprehensive screening, and partial - debt bonds should be treated with caution. [2][3][9] 2. Convertible Bond Market Tracking 2.1 Convertible Bond Market Conditions - Different convertible bond indexes have different performances in different time periods. For example, the Wind Convertible Bond Energy Index has a 0.14% increase in the past week, - 0.91% in the past two weeks, etc. [14] 2.2 Convertible Bond Issues - The report shows the top ten and bottom ten convertible bond issues in terms of price changes in the past week, but specific issue names are not provided in the text. [18] 2.3 Convertible Bond Valuations - The report presents the valuation trends of different types of convertible bonds (debt - type, balanced, and equity - type) through charts, but specific data analysis is not provided in the text. [21][26][28] 2.4 Convertible Bond Prices - The report shows the proportion trends of high - price convertible bonds and the median price trends of convertible bonds through charts, but specific data analysis is not provided in the text.

Group 1: Report Industry Investment Rating - Not provided in the content Group 2: Core Viewpoints of the Report - The recent performance of the convertible bond market has been significantly weaker than that of the underlying stocks, with the core contradiction being high valuations and a lack of cost - effectiveness. The valuation compression was triggered by the equity market entering a consolidation phase, and the slowdown of incremental funds' allocation. The high valuations also led to a lack of cost - effectiveness in convertible bonds, with high premium rates for different types of convertible bonds [1][2][7]. - The expansion of convertible bond ETFs has made them a timing tool for absolute - return funds. The current stock size of convertible bond ETFs exceeds 70 billion yuan, accounting for over 10% of the convertible bond market. The investment institutions behind these ETFs are mainly absolute - return funds, and the trading flexibility of ETFs provides a good tool for them [2]. - The frequent up - and - down market movements have created opportunities for mispriced bonds. When the market shows adjustment signals, ETF funds often redeem en masse, and then quickly increase positions during the initial rebound of the underlying stocks, leading to market volatility and opportunities for active management institutions to obtain alpha [2][8]. - The optimal strategy in a volatile market is to manage positions in a hierarchical manner. In the long - term, the stock market's positive trend remains unchanged, and convertible bonds have long - term allocation value. In the short - term, the equity market is in a wide - range oscillation. It is recommended to layout industries that benefit from the shift from high - to low - priced stocks at low levels, and make different arrangements for high - priced bonds according to their characteristics. In September, it is suggested to pay attention to bonds such as Shangyin Convertible Bond, Shouhua Convertible Bond, etc. [2][8] Group 3: Summary According to the Table of Contents 1. Convertible Bond Weekly Thinking - The convertible bond market has underperformed the underlying stocks recently, mainly due to high valuations and a lack of cost - effectiveness. The valuation compression was triggered by changes in the equity market and the behavior of incremental funds. High valuations have also made convertible bonds less attractive. The expansion of convertible bond ETFs has changed their role, and the up - and - down market movements have created mispricing opportunities. A hierarchical position management strategy is recommended [7][8] 2. Convertible Bond Market Tracking 2.1 Convertible Bond Market Conditions - Provided the performance data of various convertible bond indices in different time periods, including the past week, two weeks, September to date, one month, two months, half - year, and one year. For example, the Wind Convertible Bond Energy Index had a - 1.05% change in the past week, - 1.33% in the past two weeks, etc. [13] 2.2 Convertible Bond Individual Securities - Presented the top ten and bottom ten individual convertible bonds in terms of price changes in the past week, but specific bond names were not provided [17] 2.3 Convertible Bond Valuations - Included the valuation trends of bond - type, balanced, and equity - type convertible bonds, as well as the valuation trends of convertible bonds with different parities [19][25] 2.4 Convertible Bond Prices - Showed the proportion trend of high - priced bonds and the median price trend of convertible bonds [27]

Group 1 - The report highlights that from September 15 to 19, the equity market showed a decline after a period of strength, with the Wande All A index closing at 6209.37, down 0.18% from September 12, while the China Convertible Bond index fell by 1.55, indicating a continued state of valuation retreat [1][9]. - Despite increased market volatility in September, there is a persistent inflow of funds into thematic ETFs, suggesting that investors are not abandoning thematic pursuits but are instead looking for new opportunities to capitalize on [1][16]. - The report notes that low-priced stocks have shown significant excess returns in September, which some investors associate with a potential end to the bull market; however, the report argues that this strength may be linked to retail investor participation and market style shifts rather than signaling a market downturn [2][54]. Group 2 - The report discusses the reasons behind the excess returns of low-priced stocks, including the influence of small investors who find it easier to invest in low-priced stocks due to minimum trading unit restrictions, which limits their ability to purchase high-priced stocks [2][43]. - It is noted that low-priced stocks often follow a pattern of rallying after small-cap stocks during liquidity-driven bull markets, as seen in previous cycles from 2014 to 2015 [2][46]. - The convertible bond market has faced increased trading difficulties following sharp price fluctuations, with valuation compression observed, leading to a challenging investment environment [3][59].

Quantitative Models and Construction Methods 1. Model Name: "百元转股溢价率" (100 Yuan Conversion Premium Rate) - **Model Construction Idea**: This model compares the valuation of convertible bonds and their underlying stocks by calculating a time-series comparable valuation indicator, "百元转股溢价率", and uses rolling historical percentiles to measure the relative allocation value between convertible bonds and stocks [3][13] - **Model Construction Process**: 1. Fit the relationship curve between the conversion premium rate and conversion value in the cross-sectional space at each time point 2. Substitute a conversion value of 100 into the fitted formula to obtain the "百元转股溢价率" 3. Formula: $$ y_{i} = \alpha_{0} + \alpha_{1} \cdot \frac{1}{x_{i}} + \epsilon_{i} $$ - \( y_{i} \): Conversion premium rate of the \( i \)-th bond - \( x_{i} \): Conversion value of the \( i \)-th bond - \( \alpha_{0}, \alpha_{1} \): Fitted coefficients - \( \epsilon_{i} \): Residual term [43] - **Model Evaluation**: The rolling three-year and five-year percentiles of this indicator are at 98.00% and 93.70%, respectively, indicating that convertible bonds are relatively expensive compared to stocks [3][13] 2. Model Name: "修正 YTM – 信用债 YTM"中位数 (Modified YTM - Credit Bond YTM Median) - **Model Construction Idea**: This model evaluates the relative allocation value between debt-oriented convertible bonds and credit bonds by stripping the impact of conversion terms on the convertible bond's yield-to-maturity (YTM) [4][13] - **Model Construction Process**: 1. Adjust the YTM of debt-oriented convertible bonds using the formula: $$ \text{Modified YTM} = \text{Convertible Bond YTM} \times (1 - \text{Conversion Probability}) + \text{Expected Conversion Yield} \times \text{Conversion Probability} $$ 2. Calculate the conversion probability using the Black-Scholes (BS) model, incorporating stock price, strike price, stock volatility, remaining term, and discount rate 3. Compute the difference between the modified YTM and the YTM of credit bonds with the same rating and term 4. Take the median of these differences across all debt-oriented convertible bonds: $$ \text{"修正 YTM – 信用债 YTM"中位数} = \text{median}\{X_1, X_2, ..., X_n\} $$ - \( X_i \): Difference for the \( i \)-th bond - \( n \): Number of debt-oriented convertible bonds [44] - **Model Evaluation**: The current median value is -2.48%, indicating that the overall cost-effectiveness of debt-oriented convertible bonds is relatively low [4][13] --- Quantitative Factors and Construction Methods 1. Factor Name: 转股溢价率偏离度 (Conversion Premium Deviation) - **Factor Construction Idea**: Measures the deviation of the conversion premium rate from its fitted value, making it comparable across different parities [18] - **Factor Construction Process**: - Formula: $$ \text{Conversion Premium Deviation} = \text{Conversion Premium Rate} - \text{Fitted Conversion Premium Rate} $$ - The number of convertible bonds determines the fitting quality [18] 2. Factor Name: 理论价值偏离度 (Theoretical Value Deviation) - **Factor Construction Idea**: Measures the price expectation difference using a Monte Carlo simulation that fully considers the terms of convertible bonds (e.g., conversion, redemption, downward revision, and resale) [18] - **Factor Construction Process**: - Formula: $$ \text{Theoretical Value Deviation} = \frac{\text{Convertible Bond Closing Price}}{\text{Theoretical Value}} - 1 $$ - Theoretical value is calculated by simulating 10,000 paths at each time point using the Monte Carlo method, with the same credit term interest rate as the discount rate [18] 3. Factor Name: 转债综合估值因子 (Convertible Bond Comprehensive Valuation Factor) - **Factor Construction Idea**: Combines the above two factors to enhance the systematic allocation value of convertible bonds [17][18] - **Factor Construction Process**: - Formula: $$ \text{Convertible Bond Comprehensive Valuation Factor} = \text{Rank(Conversion Premium Deviation)} + \text{Rank(Theoretical Value Deviation)} $$ - Select the top 1/3 of convertible bonds based on this factor to construct low-valuation indices for different styles (e.g., equity-biased, balanced, debt-biased) [18][19] 4. Factor Name: 转债市场情绪捕捉指标 (Convertible Bond Market Sentiment Capture Indicator) - **Factor Construction Idea**: Captures market sentiment using momentum and volatility deviation of convertible bonds [24] - **Factor Construction Process**: - Formula: $$ \text{Market Sentiment Capture Indicator} = \text{Rank(20-day Momentum)} + \text{Rank(Volatility Deviation)} $$ - Use the median value of these indicators within low-valuation style indices to determine sentiment [25] --- Backtesting Results of Models 1. "百元转股溢价率" Model - Rolling three-year percentile: 98.00% - Rolling five-year percentile: 93.70% [3][13] 2. "修正 YTM – 信用债 YTM" Model - Current median value: -2.48% [4][13] --- Backtesting Results of Factors 1. 转债综合估值因子 - Equity-biased convertible bond low-valuation index: - Annualized return: 25.46% - Annualized volatility: 20.55% - Maximum drawdown: -22.94% - IR: 1.24 - Calmar ratio: 1.11 - Monthly win rate: 62.64% [21] - Balanced convertible bond low-valuation index: - Annualized return: 14.85% - Annualized volatility: 11.88% - Maximum drawdown: -15.95% - IR: 1.25 - Calmar ratio: 0.93 - Monthly win rate: 62.64% [21] - Debt-biased convertible bond low-valuation index: - Annualized return: 13.31% - Annualized volatility: 9.50% - Maximum drawdown: -17.78% - IR: 1.40 - Calmar ratio: 0.75 - Monthly win rate: 58.24% [21] 2. 转债市场情绪捕捉指标 - Convertible bond style rotation strategy: - Annualized return: 24.37% - Annualized volatility: 16.71% - Maximum drawdown: -15.89% - IR: 1.46 - Calmar ratio: 1.53 - Monthly win rate: 64.84% [30]

Core Viewpoint - The convertible bond market is experiencing significant growth, driven by the overall rise in the A-share market and increasing institutional demand, despite a notable reduction in the supply of convertible bonds due to strong redemptions and maturities [1][2]. Group 1: Market Performance - The A-share market has reached new highs not seen since 2015, with the China Convertible Bond Index also hitting a new peak, closing at 490.98 points, a 0.46% increase [1]. - The scarcity of convertible bonds has attracted substantial inflows from public funds, insurance, and bank wealth management products, contributing to the market's upward momentum [1]. Group 2: Valuation Metrics - The median price of convertible bonds has risen to 130 yuan, indicating a high absolute price level [1][2]. - The convertible bond market's conversion premium rate stands at 27%, suggesting a relatively reasonable valuation despite the high median price [2]. Group 3: Investment Considerations - The acceleration of strong redemptions is expected as the median price exceeds 130 yuan, making it crucial for investors to avoid convertible bonds that may be subject to early redemption [3]. - Investors face dual pressures of compressed premiums and increased selling from a rapidly expanding circulation if early redemptions occur unexpectedly [3].

1. Report Industry Investment Rating - Not provided in the given content 2. Core View of the Report - The convertible bond market continues to rise with the equity market, with trading volume exceeding 10 billion yuan for multiple days. The market's fear and sensitivity to high valuations have decreased. Although high valuations still suppress the willingness to increase positions, most institutions choose to maintain their current positions and profit from high - to - low rotations. In the short term, there are no domestic negative factors, and the impact of the semi - annual reports is limited. With optimistic expectations for equities, convertible bonds may continue to break through. If there is a correction, the opportunities outweigh the risks, and appropriate low - buying can be considered. The equity market is expected to strengthen with fluctuations, and the driving force of this bull market comes from the improvement of grass - roots governance capabilities and technological competitiveness, which boosts public confidence [5][8]. 3. Summary by Relevant Catalog 3.1 Convertible Bond View: Trading Heat Hits a New High, and Valuation Has Not Peaked - The convertible bond market continues to rise with the equity market, and trading volume has exceeded 10 billion yuan for multiple days, last seen in the September 24, 2024, market. The market's fear and sensitivity to high valuations have decreased. Currently, the positions of public - offering convertible bonds are generally not high, and the previous profit - taking sentiment has changed. However, high valuations still suppress the willingness to increase positions, and most institutions choose to maintain their current positions and profit from high - to - low rotations. There are no short - term domestic negative factors, and the impact of the semi - annual reports is limited. With optimistic expectations for equities, convertible bonds may continue to break through, and if there is a correction, the opportunities outweigh the risks, allowing for appropriate low - buying [8]. - Last week, the A - share market continued to rise. Policies and data such as the suspension of the 24% tariff between China and the US for 90 days, the introduction of interest - subsidy policies to stimulate consumption, and a slight rebound in the CPI in July had a positive impact on market sentiment. The Shanghai Composite Index once exceeded 3700 points, with the financial and technology sectors leading the rise, especially the securities brokerage sector, which boosted market sentiment. The equity market is expected to strengthen with fluctuations, and the driving force of this bull market comes from the improvement of grass - roots governance capabilities and technological competitiveness, which boosts public confidence [8]. 3.2 Convertible Bond Review: The Stock Market Reaches a New High, and Convertible Bonds Rise Accordingly 3.2.1 Market Overall Performance: The Equity Market Rises with Increased Volume, Led by Technology and Securities Brokerage - From August 11th to August 15th, the market rose with increased volume. The Shanghai Composite Index rose 1.70%, the Shenzhen Component Index rose 4.55%, the CSI 300 rose 2.37%, the CSI 1000 rose 4.09%, the ChiNext Index rose 8.58%, the STAR 50 rose 5.53%, and the Beijing Stock Exchange 50 rose 2.40%. In terms of industries, communication, electronics, and non - bank finance led the rise, while banking, steel, and textile clothing led the decline. The average daily trading volume increased significantly by 404.382 billion yuan to 2.1 trillion yuan [11]. - The top ten convertible bonds in terms of gains last week were Outong, Dayuan, Jintong, Weixin, Youzu, Dongcai, Bo23, Zhongqi, Huamao, and Dongjie Convertible Bonds. In terms of trading volume, Outong, Dayuan, Jiaojian, Zhongqi, Dongjie, Tianlu, Rongtai, Haitai, Saili, and Dongcai Convertible Bonds were relatively active [11]. 3.2.2 Convertible Bonds' Trading Volume Hits a New High, with High - Priced and Small - Cap Bonds Leading the Rise - Last week, convertible bonds significantly followed the rise, with the average daily trading volume increasing significantly to 9.3085 billion yuan. The CSI Convertible Bond Index rose 1.60%, the parity center rose 0.8% to 109.4 yuan, and the conversion premium rate center decreased 0.5% to 21.3%. In terms of style, high - priced and small - cap convertible bonds performed well last week, while AAA - rated and large - cap convertible bonds were relatively weak [15].

- The report discusses the valuation of convertible bonds (CB) using the pricing deviation indicator, which is calculated as the ratio of the CB price to the CCBA model price minus one. As of August 15, 2025, the pricing deviation indicator for the CB market is 5.42%, placing it in the 99.9th percentile since 2018, indicating a high valuation zone[6] - The report also mentions a rotation strategy between CBs and a stock-bond portfolio based on the pricing deviation indicator. The strategy involves calculating a Z-score from the pricing deviation and its standard deviation over the past three years, then adjusting the CB weight accordingly. This strategy has historically generated stable excess returns[21][23] - The report evaluates different CB strategies, including a low-valuation strategy, a low-valuation plus strong momentum strategy, a low-valuation plus high turnover strategy, a balanced debt-enhanced strategy, a credit bond replacement strategy, and a volatility control strategy. Each strategy is constructed using specific factors and has shown varying degrees of absolute and excess returns since 2018[33][36][40][44][48][52] Model and Factor Construction 1. **Pricing Deviation Indicator**: - **Construction Idea**: Measure the deviation of CB prices from their theoretical values - **Construction Process**: - Calculate the pricing deviation as follows: $ \text{Pricing Deviation} = \frac{\text{CB Price}}{\text{CCBA Model Price}} - 1 $ - Use this indicator to assess the valuation level of the CB market[6] - **Evaluation**: Indicates that the CB market is currently in a high valuation zone[6] 2. **Rotation Strategy Between CBs and Stock-Bond Portfolio**: - **Construction Idea**: Rotate between CBs and a stock-bond portfolio based on CB valuation - **Construction Process**: - Calculate the Z-score of the pricing deviation: $ Z = \frac{\text{Pricing Deviation}}{\text{Standard Deviation (3 years)}} $ -

**Construction Idea**: Select CBs with the lowest valuation deviations - **Construction Process**: - Use the CCB_out model to calculate the pricing deviation: $ \text{Pricing Deviation} = \frac{\text{CB Price}}{\text{CCB_out Model Price}} - 1 $ - Select the 15 CBs with the lowest deviations in each of the debt, balanced, and equity-biased categories (total 45 CBs) - Ensure the selected CBs have a balance of over 300 million and a rating of AA- or above[33] - **Evaluation**: This strategy has shown strong stability and significant absolute and excess returns since 2018[33] 4. **Low-Valuation + Strong Momentum Strategy**: - **Construction Idea**: Combine low valuation with strong momentum for higher elasticity - **Construction Process**: - Combine the pricing deviation factor with the stock momentum factor (1, 3, 6 months) - Select CBs based on combined scores[36] - **Evaluation**: This strategy has shown strong elasticity and significant absolute and excess returns since 2018[36] 5. **Low-Valuation + High Turnover Strategy**: - **Construction Idea**: Combine low valuation with high turnover for higher liquidity - **Construction Process**: - Select the lowest 50% valuation CBs - Within this pool, select CBs with the highest turnover rates (5, 21 days) and the highest CB to stock turnover ratios (5, 21 days)[40] - **Evaluation**: This strategy has shown stable excess returns and significant absolute returns since 2018[40] 6. **Balanced Debt-Enhanced Strategy**: - **Construction Idea**: Enhance returns by combining low valuation with turnover and momentum factors - **Construction Process**: - Select the lowest 50% valuation CBs, excluding equity-biased CBs - Use turnover and momentum factors for debt-biased CBs and turnover factors for balanced CBs[44] - **Evaluation**: This strategy has shown significant absolute returns with low volatility and drawdown since 2018[44] 7. **Credit Bond Replacement Strategy**: - **Construction Idea**: Replace credit bonds with CBs for higher returns - **Construction Process**: - Select CBs with YTM + 1% greater than 3-year AA credit bond YTM - Ensure selected CBs have a balance of over 300 million and a rating of AA- or above - Select the top 20 CBs based on 1-month stock momentum, with a maximum weight of 2% per CB - Use volatility control to reduce short-term drawdown, allocate remaining weight to credit bonds[48] - **Evaluation**: This strategy has shown stable returns with low volatility and drawdown since 2018[48] 8. **Volatility Control Strategy**: - **Construction Idea**: Control portfolio volatility while enhancing returns - **Construction Process**: - Select the top 15 CBs in each of the debt, balanced, and equity-biased categories based on low valuation and strong momentum scores -

1. Report Industry Investment Rating No relevant content provided. 2. Core Views of the Report - The current valuation of convertible bonds is relatively high from the perspective of implied volatility, close to the peak in 2022, and there is a certain risk of short - term callback in the convertible bond index [10][17]. - The A - share market still shows good allocation cost - performance, and the weak resonance between the domestic economic fundamentals and the capital market is expected to gradually start. In the convertible bond market, considering the impact of refinancing policies, there is certain support on the demand side under the background of shrinking supply. However, be vigilant about the callback risk as the overall valuation is already at a relatively high level [21]. - In terms of industries, pay attention to popular themes, domestic demand - oriented sectors, central state - owned enterprises represented by "China -字头", and the military industry [22]. 3. Summary According to the Directory 3.1. Convertible Bond Weekly Special and Outlook 3.1.1. Implied Volatility: How about the Current Valuation of Convertible Bonds? - As of this Friday, the closing point of the China Securities Convertible Bond Index reached 475.25, a new high in recent years, with a year - to - date increase of 14.64%, slightly lower than the 16.19% increase of the Wind All - A Index [10]. - The overall implied volatility of convertible bonds has been rising since September 2024 and is now significantly higher than the annual highs since 2018. The implied volatility difference has accelerated its upward trend since April this year and is now above the 95% historical quantile, indicating that the overall valuation of convertible bonds is at a relatively high historical level [10]. - There is a certain differentiation in the valuation of convertible bonds. The valuation of convertible bonds with a parity of 50 - 80 is at a high historical quantile, while that of convertible bonds with a parity greater than 120 is relatively low. Some convertible bonds may still have room for valuation improvement [11]. - The RSJ_60 indicator of the China Securities Convertible Bond Index is currently above the 95% quantile of the past year, suggesting a certain short - term callback risk [17]. 3.1.2. Weekly Review and Market Outlook - This week, the market fluctuated upwards. The A - share market had mixed performance on different days, with various sectors rising and falling. Looking ahead, the A - share market shows good allocation cost - performance. The domestic economic fundamentals are expected to gradually resonate with the capital market [18][21]. - In the convertible bond market, pay attention to the game space of downward revision clauses, be vigilant about the forced redemption risk, and appropriately focus on the short - term game opportunities of near - maturity convertible bonds [21]. - Industries to focus on include popular themes, domestic demand - oriented sectors, central state - owned enterprises, and the military industry [22]. 3.2. Weekly Tracking of the Convertible Bond Market 3.2.1. Equity Market Closed Higher - This week, major equity market indices closed higher.

Summary by Relevant Catalogs 3.1 Weekly View and Outlook - **Low - volatility and Mid - to High - priced Convertible Bonds**: Since 2025, the imbalance between supply and demand in the convertible bond market has led to strong performance of traditional low - priced convertible bonds. The median price of the whole market has been rising, and the premium rate of low - parity convertible bonds is at a historical high. Due to the lack of elasticity in the underlying stock fundamentals and strong call expectations, there may be price - fluctuation risks at high premium rates, so trading is preferred over allocation [4][5]. - **High - elasticity and High - priced Convertible Bonds**: These are traditional high - parity and high - priced convertible bonds with high volatility. In Q2 2025, their performance was relatively limited, and the valuation was not high, with strong call risks being a significant constraint. However, the underlying stock fundamentals are relatively good, and the support logic is clear. Since Q3, their elasticity has gradually been released. Even if a call notice is issued, the impact on the bond price is expected to be controllable in the context of sufficient liabilities.
