英文摘要:
Stock correlations is crucial to asset pricing, investor decision-making, and financial risk regulations. However, microscopic explanation based on agent-based modeling is still lacking. We here propose a model derived from minority game for modeling stock correlations, in which an agent\'s expected return for one stock is influenced by the historical return of the other stock. Each agent makes a decision based on his expected return with reference to information dissemination and the historical return of the stock. We find that the returns of the stocks are positively (negatively) correlated when agents\' expected returns for one stock are positively (negatively) correlated with the historical return of the other. We provide both numerical simulations and analytical studies and give explanations to stock correlations for cases with agents having either homogeneous or heterogeneous expected returns. The result still holds when other factors such as holding decisions and external events are included which broadens the practicability of the model.

中文摘要:
股票相关性对资产定价、投资者决策和金融风险监管至关重要。然而,基于agent建模的微观解释仍然缺乏。本文提出了一个基于少数群体博弈的股票相关性建模模型,其中一个代理对一只股票的预期回报率受另一只股票的历史回报率的影响。每个代理人根据其预期回报,参考信息传播和股票的历史回报,做出决策。我们发现,当代理人对一只股票的预期收益与另一只股票的历史收益正(负)相关时,股票的收益正(负)相关。我们提供了数值模拟和分析研究,并对具有同质或异质预期回报的代理的股票相关性进行了解释。当考虑其他因素(如举行决策和外部事件)时,结果仍然成立,这拓宽了模型的实用性。
