Summary of Anxin Capital Fixed Income Report

This report analyzes the key changes and dynamics in convertible bond (debt-to-equity) price adjustment (下修) for the first half of 2023, based on Anxin Securities' Fixed Income theme research. The analysis covers motivations,博弈 logic, risks, and case studies.

Key Findings for 2023 Half-Year

A total of 23 convertible bonds underwent successful price adjustments in 2023年上半年 (January to June), surpassing the 2022同期 level.
Adjustments were more frequent during stock market downturns, driven by triggers like avoiding put-back obligations or缓解 financial pressure.
Motivations vary by industry: non-bank companies focus on shareholder减持 or reducing expenses, while banks aim to boost core capital.
Regulatory changes shortened the decision window, reducing costs but increasing risks such as more partial adjustments or outright rejection (over 70% of cases in 2023).

Downward Adjustment Gameplay Logic

Gains from adjustments stem from higher conversion parity, elevating bond prices.
Optimal intervention points are before or on the board proposal date, with a 84% win rate and average 28% return from 2018 data, based on backtesting.
Risks include no adjustment, failed board approval, or incomplete adjustments, leading to price declines.
For short-term play, the board proposal day sees high returns, but later stages carry higher risks with lower win rates.

Changes in 2023

Stock market volatility increased opportunities due to more trigger events.
However, risks rose significantly, with a shift toward partial adjustments and more refusals, reflecting issuer confidence in stock prices.
Backtesting for 2023下修 events shows higher variability, with intervention before proposals offering better returns.

Case Studies

Strong Link Bond: Full adjustment exceeded expectations, boosting bond price and facilitating conversion.
Healthy Sail Bond: Partial adjustment fell short, causing price drops and missed opportunities.
Zeng Bang Bond: Unexpected full adjustment aided stock conversion, reducing risk for holders.

##总体 Insight
Investors face a trade-off between higher potential returns with timely action and increased risks in 2023, particularly with more partial adjustments. Focus on pre-announcement intervention for better outcomes, but monitor for adjustment failures.
