Penalty methods for bilateral XVA pricing in European and American contingent claims by a partial differential equation model
Under some assumptions, the valuation of financial derivatives, including a value adjustment to account for default risk (the so-called XVA), gives rise to a nonlinear partial differential equation (PDE). The authors propose numerical methods for…
‘Rough volatility’ models promise better pricing and hedging of options. But will they catch on?
In the most realistic simulations, data-driven approach fared 30% worse than conventional hedging
The authors devise a neural network-based compression/completion methodology for financial nowcasting.

Research on ‘rough volatility’ gives fresh insight into financial fluctuations, quant expert explains
The authors consider the problem of finding a valid covariance matrix in the foreign exchange market given an initial nonpositively semidefinite (non-PSD) estimate of such a matrix.

Bourse draws criticism over timing of options model change; delay in sending key margin file
New research addresses fundamental issues with ANN approximation of pricing models
In this paper, the authors investigate a nonlinear generalization of the Black–Scholes equation for pricing American-style call options, where the volatility term may depend on both the underlying asset price and the Gamma of the option.
In this paper, the authors propose a bivariate interpolation of the implied volatility surface based on Chebyshev polynomials. This yields a closed-form approximation of the implied volatility, which is easy to implement and to maintain.
In this paper, the authors analyse the convergence of tree methods for pricing barrier and lookback options.
Quants are embracing the idea of ‘model free’ pricing and hedging
