金融动力学中的交叉相关性

Cross-correlation in financial dynamics

J. Shen, B. Zheng

摘要:

为了研究金融动力学中相互作用的普遍结构,我们分析了中国股票市场价格收益的交叉相关矩阵C,并与美国和印度股票市场的交叉相关矩阵C进行了比较。作为一个重要的新兴市场,中国市场表现出比发达市场更强的相关性。在中国市场上,同一行业的股票之间的相互作用很弱,而在异常行业中检测到额外的相互作用。利用双因子模型的一个变体,我们模拟了金融市场中的相互作用.

英文摘要:

To investigate the universal structure of interactions in financial dynamics, we analyze the cross-correlation matrix C of price returns of the Chinese stock market, in comparison with those of the American and Indian stock markets. As an important emerging market, the Chinese market exhibits much stronger correlations than the developed markets. In the Chinese market, the interactions between the stocks in a same business sector are weak, while extra interactions in unusual sectors are detected. Using a variation of the two-factor model, we simulate the interactions in financial markets.
