Low-Price Convertible Bond Rotation and Its Credit-Risk Dependence
Summary
The document explains a convertible-bond rotation strategy that ranks bonds by absolute price and holds a selected group of the cheapest issues. Unlike a double-low approach, it does not use conversion premium as a selection variable. Its thesis depends on bond-floor support, potential put protection, and the possibility that issuers lower conversion prices to encourage conversion. The strategy assumes issuers are unlikely to default and have reasons to convert debt into equity.
A historical test spanning 2018 through October 2022 reports strong risk-adjusted results and lower volatility than a convertible-bond index, while returns were slightly below the double-low strategy. It describes relative resilience in equity-market declines, alongside weaker participation when risk appetite and valuations recover. The evidence is limited to that sample and does not establish future performance. Credit events can undermine the bond-floor assumption: the document cites a market episode in which default fears hurt valuations, especially among weaker issuers. It also flags liquidity, macroeconomic and equity-market shocks, and delayed public data as risks; screening only by cheapness requires attention to underlying issuer fundamentals.
Key ideas
- The strategy ranks convertible bonds by absolute price and rotates into the cheapest issues, without considering conversion premium.
- Its expected support comes from bond value and put features, while conversion-price reductions may provide upside potential.
- The historical test reports lower volatility and defensive behavior, with less upside participation than a double-low strategy.
- The thesis relies on limited credit risk; a credit shock can weaken the bond floor and harm cheap, lower-quality issues.
- Low price alone is not a sufficient assessment of issuer quality, and the reported sample does not guarantee future results.
