摘要翻译:
股票之间的相关系数依赖于价格历史,包含了金融市场中的层次结构信息。这对于投资组合的选择和风险的估计都是有用的。我引入了股票价格之间相关性的生命时间,以知道我们应该研究多大程度的价格历史,以获得最优的相关性持久性。我对新兴市场(波兰)和成熟市场(美国、英国和德国)进行研究。本文还讨论了其它方法,包括最小生成树、树的半衰期、相关分解和Epps效应。

英文摘要:
The correlation coefficient between stocks depends on price history and includes information on hierarchical structure in financial markets. It is useful for portfolio selection and estimation of risk. I introduce the Life Time of Correlation between stocks prices to know how far we should investigate the price history to obtain the optimal durability of correlation. I carry out my research on emerging (Poland) and established markets (in the USA, Great Britain and Germany). Other methods, including the Minimum Spanning Trees, tree half-life, decomposition of correlations and the Epps effect are also discussed.
