概要

A lead-lag effect in stock markets describes the situation where one (leading) stock return is cross-correlated with another (lagging) stock return at later times. There are various methods for stock return forecasting based on such a lead-lag effect. One of the most representative methods is based on the supply chain network. In this research, we propose a stock return forecasting method with an economic causal chain. The economic causal chain refers to a cause and effect network structure constructed by extracting a description indicating a causal relationship from the texts of Japanese financial statement summaries. We examine the following lead-lag effect. (1) whether lead-lag effect spreads to the 'effect' stock group when there is a large stock fluctuation in the 'cause' stock group in the causal chain. (2) whether lead-lag effect spreads to the 'cause' stock group when there is a large stock fluctuation in the 'effect' stock group in the causal chain. We confirm the existence of the both side of lead-lag effect and the evidence of stock return predictability across causally linked firms in the Japanese stock market.
