金融市场指数网络的聚类形成与演化

Cluster formation and evolution in networks of financial market indices

Leonidas Sandoval Junior

摘要:

利用全球金融危机之前和期间世界证券交易所指数的数据,为不同的阈值和不同的时间段建立指数集群和网络,从而可以分析集群是如何根据指数之间的相关性形成的,以及它们如何随时间演变,特别是在金融危机期间。进一步分析了对应于相关矩阵次高特征值的特征向量,揭示了运行在不同时区的市场所特有的结构。

英文摘要:

Using data from world stock exchange indices prior to and during periods of global financial crises, clusters and networks of indices are built for different thresholds and diverse periods of time, so that it is then possible to analyze how clusters are formed according to correlations among indices and how they evolve in time, particularly during times of financial crises. Further analysis is made on the eigenvectors corresponding to the second highest eigenvalues of the correlation matrices, revealing a structure peculiar to markets that operate in different time zones.
