Core Viewpoint - The convertible bond market has shown strong performance in 2023, with the China Convertible Bond Index rising by 17.14% year-to-date and total trading volume reaching 13.46 trillion yuan, a year-on-year increase of 37.75%. This has led to increased interest in quantitative investment strategies that leverage the unique characteristics of convertible bonds, which offer both offensive and defensive capabilities [1]. Group 1: Why Choose Convertible Bonds? - Convertible bonds are considered high-quality beta assets, with the China Convertible Bond Index significantly outperforming major broad-based indices since 2017. For instance, during the market downturn in 2018, the index only fell by 1.16%, while the CSI 300 and CSI 500 indices dropped by 25.31% and 33.32%, respectively. Conversely, in 2019, the index rose by 25.15%, demonstrating its ability to provide both growth and protection [3][4]. Group 2: Characteristics and Pricing Factors of Convertible Bonds - The core value of convertible bonds is tied to the underlying stock price, which directly influences their conversion value. The bonds exhibit a "dual nature" of equity and debt, allowing them to appreciate in value with rising stock prices while providing a "debt floor" during downturns [8][10]. - The interest rate environment plays a crucial role in shaping the "debt floor" of convertible bonds. A decrease in market interest rates enhances the attractiveness of convertible bonds as fixed-income assets, thereby supporting their price [10]. - Unique terms such as price adjustment clauses can create opportunities for value enhancement. When the stock price falls below a certain threshold, companies can lower the conversion price, increasing the number of shares each bond can convert into, thus boosting its market value [10][11]. - Supply and demand dynamics significantly impact the valuation of convertible bonds. The issuance pace and scale of convertible bonds are influenced by new stock offerings and refinancing policies, while institutional demand from public funds and insurance companies also plays a critical role [11]. Group 3: Common Quantitative Strategies for Convertible Bonds - Quantitative strategies for investing in convertible bonds involve using computer models to systematically identify and execute investment opportunities, minimizing emotional decision-making. Common strategies include: - **Dual Low Strategy**: Focuses on bonds with low prices and low conversion premiums to balance safety and upside potential [12]. - **Low Premium Strategy**: Targets bonds with very low or negative conversion premiums, capitalizing on strong stock performance [12]. - **High YTM Strategy**: Treats convertible bonds as fixed-income securities to secure stable interest income, particularly in bearish or volatile markets [12]. - **Event-Driven Strategy**: Monitors events that may cause price fluctuations, such as earnings announcements or proposed conversion price adjustments, to capitalize on market reactions [12].

Investment Rating - The report does not explicitly provide an investment rating for the convertible bond sector, but it discusses the relative performance and suitability of different types of convertible bonds, indicating a preference for balanced and bond-like convertible bonds for long-term holding [7][13]. Core Insights - The report emphasizes the value of convertible bonds in terms of allocation and timing strategies, categorizing them into bond-like, balanced, and equity-like convertible bonds. It suggests that balanced and bond-like convertible bonds have higher risk premiums and are better suited for long-term investment, while equity-like convertible bonds offer better timing opportunities due to their lower risk premiums [1][7][13]. - The report highlights the performance of convertible bonds in the recent market, noting that the equity-like convertible bonds performed the best in the last month, driven by stock contributions, while the overall market experienced a decline followed by a rebound [3][29]. Summary by Sections Convertible Bond Allocation and Timing Value - Convertible bonds can be categorized into bond-like, balanced, and equity-like types based on their pricing deviations. The report suggests that balanced and bond-like convertible bonds are more suitable for long-term investment due to their higher Sharpe and Calmar ratios compared to equity-like convertible bonds, which have higher volatility and drawdowns [1][7][11]. Market Review: Convertible Bond Market Downturn and Rebound - The convertible bond market experienced a downturn followed by a rebound, with stock contributions providing a positive return of 0.31% while valuation adjustments led to a negative return of -0.83% over the past month. Equity-like convertible bonds showed the strongest performance, with a positive stock contribution of 2.18% [3][29]. Convertible Bond Strategy Tracking - The report outlines various strategies for selecting and timing convertible bonds, including a low valuation strategy that has achieved a 21.7% absolute return since 2018. The strategy focuses on selecting the lowest priced convertible bonds and adjusting allocations based on relative valuations [32][40].

- Convertible bond allocation and timing strategies are divided into three categories: debt-biased, balanced, and equity-biased convertible bonds. Allocation is based on equal weighting, with bonds meeting criteria such as a balance of over 3 billion and a rating of AA- or above. Debt-biased and balanced convertible bonds show higher Sharpe and Calmar ratios, indicating better long-term allocation value, while equity-biased convertible bonds exhibit higher annualized returns but greater volatility and drawdowns, making them less suitable for long-term holding[7][11][13] - CCBA pricing deviation indicator (convertible bond price/CCBA model pricing - 1) is introduced as a timing factor. This indicator effectively measures the option valuation level of convertible bonds and is used to construct timing strategies for debt-biased, balanced, and equity-biased convertible bonds. The strategy adjusts weights based on the Z-score of the past three years' pricing deviation, reducing convertible bond allocation when valuation is high[8][12][13] - Timing strategies significantly improve performance for equity-biased convertible bonds, with Sharpe and Calmar ratios increasing to 0.87 and 0.74, respectively. For debt-biased and balanced convertible bonds, timing has less impact, suggesting these categories are better suited for long-term allocation without frequent adjustments[13][16][17] - Relative return strategies include the "low valuation strategy," which selects the 15 convertible bonds with the lowest pricing deviation from the CCBA_out model in each category (debt-biased, balanced, equity-biased). This strategy achieves an annualized return of 21.7% and an excess return of 12.3% since 2018, demonstrating strong stability even during market downturns[32][35][36] - The "low valuation + strong momentum strategy" combines pricing deviation factors with stock momentum factors (1, 3, 6-month momentum scores). This strategy achieves an annualized return of 24.5% and an excess return of 14.7% since 2018, showing higher elasticity and strong performance in 2023 with a 9.0% absolute return[35][37][40] - The "low valuation + high turnover strategy" selects the lowest 50% valuation convertible bonds and further filters based on high turnover factors (5-day and 21-day turnover rates). This strategy achieves an annualized return of 23.4% and an excess return of 13.7% since 2018, with stable excess returns in 2023 and a 10.9% absolute return[39][41][44] - Absolute return strategies include the "balanced debt-biased enhancement strategy," which uses turnover rate factors and stock momentum factors for debt-biased bonds and turnover rate factors for balanced bonds. This strategy achieves an annualized return of 23.1% since 2018, with low volatility and drawdowns[44][45][47] - The "credit bond substitution strategy" selects convertible bonds with YTM+1% greater than 3-year AA-rated credit bond YTM, combined with stock momentum factors for allocation. This strategy achieves an annualized return of 7.3% since 2018, with volatility and drawdowns below 3%[48][51][52] - The "volatility control strategy" combines enhanced strategies for debt-biased, balanced, and equity-biased convertible bonds with credit bonds, controlling portfolio volatility at 4%. This strategy achieves an annualized return of 10.0% since 2018, with volatility and drawdowns around 4%-5%[53][55][56]
