BV534 Investigating Volatility Haircuts/Caps in Convertible Bonds Valuation

Webinar Description

It is commonly seen in practice that a volatility “haircut” or “cap” – reducing the volatility if the market data suggests an elevated volatility level – is applied to appropriately price the convertible bonds, under the assumption that the convertible markets do not typically price in the full volatility at elevated levels. In this study, a set of traded convertible bonds with observable yields were selected and valued, and the model values were compared against observable traded values. Volatility caps were subsequently introduced and differences in model vs market prices were investigated. We find evidence to support the notion that market prices for convertibles do not always reflect the observed levels of volatility, and that using the observed volatility without an adjustment may result in overvaluing the convertible instruments in some cases.

Learning Outcomes

Upon webinar completion, the participant will be able to:

  • Analyze the volatility input for convertible notes; 
  • Identify situations where a cap on a volatility may be appropriate;
  • Apply appropriate caps and/or haircuts to the volatility input; and
  • Discuss nuances of volatility estimation for convertible bonds with low vs high credit quality.
