confidence ability and herding ability

Description

We use the trading data of Wanke corporation to compute the trader’s confidence ability and herding ability, which is described in detail in our paper “The dynamics of heterogeneous investors’ trading pattern——the perspective from the level of confidence and herding”. The typical trader Bayesian updates the memory coefficients of his confidence ability and herding ability based on a monthly frequency, respectively. We show the patterns of confidence ability based on the trader’s past performance and herding ability based on the recent market ups and downs.
