Discrete time hedging in a complete diffusion market is considered. The hedge portfolio is rebalanced when the absolute difference between delta of the hedge portfolio and the derivative contract reac...
Models of self-financing hedging strategies in illiquid markets: symmetry reductions and exact solutions
nonlinear PDEs illiquid markets option pricing invariant reductions
2010/10/21
We study the general model of self-financing trading strategies in illiquid markets introduced by Schoenbucher and Wilmott, 2000. A hedging strategy in the framework of this model satisfies a nonlinea...
Approximations and asymptotics of upper hedging prices in multinomial models
