落后还是不落后?如何比较在不同时间运行的股票市场指数

To lag or not to lag? How to compare indices of stock markets that operate at different times

Leonidas Sandoval Junior

摘要:

全球金融市场的工作时间并不相同。因此,金融市场指数之间的相关性或因果关系的研究变得依赖于我们是否应该考虑在计算相关矩阵的所有指数在同一天或滞后指数。本文提出的答案是,我们应该考虑两者。在这项工作中,我们使用79个指数的多样性股票市场在世界各地,以研究他们的相关性结构,并发现,在同一个网络中表示原始和滞后指数,我们获得了更好的理解,如何在不同的时间运行的指数相互关联。

英文摘要:

Financial markets worldwide do not have the same working hours. As a consequence, the study of correlation or causality between financial market indices becomes dependent on wether we should consider in computations of correlation matrices all indices in the same day or lagged indices. The answer this article proposes is that we should consider both. In this work, we use 79 indices of a diversity of stock markets across the world in order to study their correlation structure, and discover that representing in the same network original and lagged indices, we obtain a better understanding of how indices that operate at different hours relate to each other.
