Analyzing the Role of Noise Trader in Financial Markets through Agent-Based Modelling

摘要

This article investigates the role of noise traders in financial markets by using an agent-based model. In this study, I analyze the market where various kinds of investors, including fundamentalists and investors who employ a passive investment strategy (which is one of the most popular investment strategies in the asset management business), are present. As a result of intensive experimentation, it was concluded that noise traders, such as investors who evaluate stock prices based on trends, averages, and latest prices, could contribute to the survival of fundamentalists and help to maintain market stability. These results are of both academic interest and practical use.
