We investigate financial markets under model risk caused by uncertain volatilities. For this purpose we consider a financial market that features volatility uncertainty. To have a mathematical consistent framework we use the notion of G-expectation and its corresponding G-Brownian motion...

This paper deals with the superhedging of derivatives on incomplete markets, i.e. with portfolio strategies which generate payoffs at least as high as that of a given contingent claim. The simplest solution to this problem is in many cases a static superhedge, i.e. a buy-and-hold strategy...

We study the valuation and hedging of unit-linked life insurance contracts in a setting where mortality intensity is …. We also show that the induced hedging strategies indeed produce a dynamic superhedge and subhedge under the statistical … by finite difference methods. For our contracts and choice of parameters the pricing and hedging is fairly robust with …

This paper provides a theoretical and numerical analysis of robust hedging strategies in diffusion?type models … including stochastic volatility models. A robust hedging strategy avoids any losses as long as the realised volatility stays …

When options are traded, one can use their prices and price changes to draw inference about the set of risk factors and … option hedging errors. We derive a closed-form solution for the option hedging error and its expecta- tion in a stochastic …, the expected hedging error cannot identify the exact structure of the compensation for jump risk. Furthermore, we derive …
