The homotopy analysis method for derivatives pricing under wrong-way risk

Derivatives pricing is approximated with a computationally efficient homotopy-based application that accounts for WWR


The valuation of wrong-way risk is a challenging task in the financial industry. In this article, Takayuki Sakuma applies the homotopy analysis method to semi-linear partial differential equations to derive an analytical approximation formula that can be computed efficiently

Wrong-way risk (WWR), which is the risk that captures the positive correlation between exposures and the default probability of the counterparty, has received a great deal of attention as a
