Contingent Claims and Hedging of Credit Risk with Equity Options

The Review of Asset Pricing Studies 2024 14(2), 310-348 open access
Using contingent-claims valuation, we introduce novel hedge ratios for credit exposures using put options. Option hedge ratios are generally in line with the empirical sensitivities of credit spread changes to put option returns and, relative to stock hedge ratios, produce further reductions in volatility for a portfolio of North American firms. We show that option hedge ratios capture option-specific credit exposure related to the VIX index and the default spread, which is unaccounted for by Merton’s (1974) equity hedge ratios alone. Combining stocks and put options for credit risk hedging can be done effectively using the volatility smirk.

The Predictive Power of the Dividend Risk Premium

Journal of Financial and Quantitative Analysis 2021 56(8), 2843-2869
We show that the dividend growth rate implied by the options market is informative about i) the expected dividend growth rate and ii) the expected dividend risk premium. We model the expected dividend risk premium and explore its implications for the predictability of dividend growth and stock market returns. Correcting for the expected dividend risk premium strengthens the evidence for the predictability of dividend growth and stock market returns both in and out of sample. Economically, a market-timing investor who accounts for the time-varying expected dividend risk premium realizes an additional utility gain of 2.02% per year.

Does CDS trading affect risk-taking incentives in managerial compensation?

Journal of Banking & Finance 2023 151, 105485 open access
We find that managers receive more risk-taking incentives in their compensation packages once their firms are referenced by credit default swap (CDS) trading, particularly when institutional ownership is high and when firms are in financial distress. These findings provide suggestive evidence that boards offer pay packages that encourage greater risk taking to take advantage of the reduced creditor monitoring after CDS introduction. Further, we show that the onset of CDS trading attenuates the effect of vega on leverage, consistent with the threat of exacting creditors restraining managerial risk appetite.
