Abstract

 

This paper develops a three-state jump-recovering-switching model (JRS model), coupling jump processes and a regime-switching methodology, to investigate the dynamic patterns and statistical properties of initial and recovering jumps in S&P 500 stock index returns from 2002-2015. The empirical findings show that a “directional effect” and a “magnitude effect,” two jump phenomena in the returns process from the perspective of overreaction, are empirically supported.
