Convergence of the fixed-point iteration for the Bass Local Volatility model

via Zoom

Speaker Dr. Gudmund Pammer, Dept. of Mathematics, ETH Zürich Abstract: The Bass local volatility model introduced by Backhoff-Veraguas–Beiglböck–Huesmann–Källblad is a Markov model perfectly calibrated to vanilla options at finitely many maturities, that approximates the Dupire local volatility model. Conze and Henry-Labordère show that its calibration can be achieved by solving a fixed-point nonlinear integral equation. […]

Risk budgeting portfolios: Existence and computation

via Zoom

Speaker: Prof. Olivier Guéant, Department of Applied Mathematics, Université Paris 1 Panthéon-Sorbonne Abstract: Modern portfolio theory has provided for decades the main framework for optimizing portfolios. Because of its sensitivity to small changes in input parameters, especially expected returns, the mean-variance framework proposed by Markowitz (1952) has however been challenged by new construction methods that […]
