摘要翻译:
利用世界上一些主要金融市场指数的相关矩阵的特征值和特征向量,我们证明了市场的高波动性与它们之间的强相关性直接相关。这意味着,在大崩盘期间,市场往往表现为一体。为了做到这一点,我们调查了1987年(黑色星期一)、1989年(俄罗斯危机)、2001年(网络泡沫破裂和911)和2008年(次贷危机)发生的几次金融市场危机,这些危机标志着过去30年来金融市场最大的衰退。

英文摘要:
Using the eigenvalues and eigenvectors of correlations matrices of some of the main financial market indices in the world, we show that high volatility of markets is directly linked with strong correlations between them. This means that markets tend to behave as one during great crashes. In order to do so, we investigate several financial market crises that occurred in the years 1987 (Black Monday), 1989 (Russian crisis), 2001 (Burst of the dot-com bubble and September 11), and 2008 (Subprime Mortgage Crisis), which mark some of the largest downturns of financial markets in the last three decades.
