Title: Open-loop equilibrium strategy for mean-variance portfolio problem under stochastic volatility Authors:  Tingjin Yan - The Chinese University of Hong Kong (China) [presenting]

Abstract: The open-loop control framework for time-consistent mean-variance (TCMV) portfolio problems is formulated in incomplete markets with stochastic volatility (SV). We offer the existence and uniqueness results of the TCMV equilibrium controls for general SV models and derive explicit closed-form equilibrium controls for several popular models, including the Heston, Hull-White and 3/2 SV models. The uniqueness of the equilibrium controls are related to the mean-reverting speed of the volatility and the investment horizon.
