摘要翻译：
席卷全球金融市场的信贷危机可能需要数年和整个职业生涯才能完全理解和分析。然而，对当前趋势的一个简短的实证调查表明，某些市场的损失，在这种情况下是美国股票市场，沿着各种股票的相关性遵循一个级联或流行病流类似的模型。这种现象将通过网络中股票收益的图形显示以及股票收益对拓扑度量的依赖来显示。最后，将讨论“流行病”或“级联”的想法是否是这场危机的隐喻或模型。

英文摘要：
The credit crisis roiling the world's financial markets will likely take years and entire careers to fully understand and analyze. A short empirical investigation of the current trends, however, demonstrates that the losses in certain markets, in this case the US equity markets, follow a cascade or epidemic flow like model along the correlations of various stocks. This phenomenon will be shown by the graphical display of stock returns across the network as well as the dependence of stock returns on topological measures. Finally, whether the idea of "epidemic" or a "cascade" is a metaphor or model for this crisis will be discussed.
