Title

Semi-Parametric Replication of Barrier-Style Claims on Price and Volatility

Abstract

We show how to price and replicate a variety of barrier-style claims written on the log price X and quadratic variation ⟨X⟩ of a risky asset. Our framework assumes no arbitrage, frictionless markets, and zero interest rates. We model the risky asset as a strictly positive continuous semimartingale with an independent volatility process. The volatility process may exhibit jumps and maybe non-Markovian. As hedging instruments, we use only the underlying risky asset, zero-coupon bonds, and European calls and puts with the same maturity as the barrier-style claim.  We consider knock-in, knock-out, and rebate claims in single and double-barrier varieties.  This is joint work with Peter Carr and Roger Lee.
