Super-replication in extremely incomplete markets

In this work we introduce the notion of extremely incomplete markets. We prove that for these markets the super–replication price coincide with the model free super–replication price. Namely, the knowledge of the model does not reduce the super–replication price. We provide two families of extremely incomplete models: stochastic volatility models and rough volatility models. Moreover, we give several computational examples. Our approach is purely probabilistic. (joint work with A.Neufeld)
