Case A: To extract “cheap” volatility in Duke Energy convertible bonds, Mark Punt, a convertible arbitrageur at KBC AIM, purchases the bonds and delta hedges them with a short position in the company’s shares. To manage the credit risk of his long convertible bond position, Mark faces a choice of hedging with CDS, shares of the company or out-of-the-money puts on the company’s stock. Key to his hedging strategy is an understanding of the observed negative correlation between credit spreads and share prices for Duke Energy. Case B: Based on a Merton-type structural model of credit risk, Steve Dash, a trader at KBC AIM, perceives that British Airways’ CDS are mispriced relative to the company’s share price. Steve has to figure out which trades to put on to exploit the potential mispricing and what the main profit drivers of this strategy are. At the same time, he needs to be aware of the risks of his strategy and whether the “mispricing” could be attributable to factors that his capital structure arbitrage model isn’t able to capture.
