Abstract

Excessively optimistic and negative investor sentiment will affect the stability of stock market. In this paper, we investigate investor sentiment diffusion considering hesitating and forgetting mechanism on homogeneous network. Different from previous studies, we introduce the exponent form forgetting rate into SEIR model and figure out the basic reproduction number and existence of equilibrium point. Meantime, the locally asymptotic stability and global stability of internal equilibrium point are established. Finally, we illustrate the impact of forgetting rate on the investor sentiment diffusion through carrying out numerical simulations.
