  • QUANTS : Convertible Bonds

    Convertible bonds are hybrids which are both equity and credit derivatives.

    QUANTS provides a specific expertise in underlying risks modeling for both action and credit derivatives and for the links between equity and credit.

    QUANTS is also able to provide advice on complex clauses of convertible bonds such as soft calls, dividend protections and exchangeables.

    Pricing and hedging

    Convertible bonds are debts issued by companies in the form of convertible bonds which can be converted into shares of the same company (simple convertible bonds) or in shares of another company (exchangeables).

    The complexity of convertible bonds comes from the modeling of underlying processes (equity, interest rates, credits) and from the specific clauses.

    Modeling of underlying processes

    The specific clauses of convertible bonds are constantly changing in order to meet the needs of issuers and investors. The issuer tries to minimize his costs of finance charges while minimizing the holder’s share of capital in case of a conversion. On the contrary, the investor requires protection mechanisms for the different events of the life cycle of the issuing company (dividend, public take-over bids, etc.) on which the price of convertible bonds strongly depends.

    Clause modeling

    The specific clauses of convertible bonds are constantly changing in order to meet the needs of issuers and investors. The issuer tries to minimize his costs of finance charges while minimizing the holder’s share of capital in case of a conversion. On the contrary, the investor requires protection mechanisms for the different events of the life cycle of the issuing company (dividend, public take-over bids, etc.) on which the price of convertible bonds strongly depends.

    These clauses are described in the leaflets with the help of a complex and rarely harmonized terminology. Their qualitative effects are often simple to approximately comprehend while the rigorous consideration and encryption of these effects are very difficult to evaluate and sometimes need to be developed.

    Applications

    Market-Making

    The market-making of convertible bonds necessitates a perfect command of pricing models and hedging. QUANTS supports its clients in their development projects of market making activities in bringing its know-how of underlying risk factor models, allowing the implementation of systematic hedging strategies.

    Arbitrage

    QUANTS’ expertise in arbitrage has been built up in assisting its clients in their development projects of systematic and discretionary strategies for derivatives (proprietary trading, hedge fund). Today, QUANTS is able to provide to its clients this unique know-how.

    Structuration

    Structuring of complex derivatives requires a perfect command of pricing and of the chosen vanilla hedging products. The complexity of the clauses of convertible bonds makes the replication more difficult. QUANTS supports its clients in their needs of modeling of new risk factors and brings its expertise for the implementation of optimal hedging strategies.

    Long-Only

    Long-Only investors used to base their approach on qualitative analysis of companies. But the convertible bonds, because of the complexity of the dynamic of underlying processes and the diversity of the clauses, make the security selection more difficult. QUANTS offers its clients systematic tools of security selection and is able to lead back-testing of quantitative strategies.

    Examples of client projects

    Convertible Bonds Arbitrage

    The project "convertible bonds arbitrage" consisted of the implementation of systematic detection tools for arbitrage of opportunities over 800 convertibles bonds.

    Thanks to its competence, QUANTS has made a systematic process of convertible bonds from the pricing process in implied volatility and implied credit spread while respecting the constraints of calculation time and data updating.

    The developed tools allow traders to improve and rationalize their investment approaches.

    Model validation of convertible bonds

    The project "model validation" consisted of the testing of a pricing model of convertible bonds, describing a new dynamic of the underlying shares and credits with a link between equity and credit.

    Thanks to its competences in modeling and back-testing, QUANTS has tested the model on a universe of convertible bonds and verified the hedge ratios to the market reality.

    The survey allows the client to prove the suitability of the new modeling under all market conditions.
