英文摘要:
Wide class of elliptically contoured distributions is a popular model of stock returns distribution. However the important question of adequacy of the model is open. There are some results which reject and approve such model. Such results are obtained by testing some properties of elliptical model for each pair of stocks from some markets. New property of equality of $\\tau$ Kendall correlation coefficient and probability of sign coincidence for any pair of random variables with elliptically contoured distribution is proved in the paper. Distribution free statistical tests for testing this property for any pair of stocks are constructed. Holm multiple hypotheses testing procedure based on the individual tests is constructed and applied for stock markets data for the concrete year. New procedure of testing the elliptical model for stock returns distribution for all years of observation for some period is proposed. The procedure is applied for the stock markets data of China, USA, Great Britain and Germany for the period from 2003 to 2014. It is shown that for USA, Great Britain and Germany stock markets the hypothesis of elliptical model of stock returns distribution could be accepted but for Chinese stock market is rejected for some cases.

中文摘要:
广义椭圆等高线分布是一种流行的股票收益率分布模型。然而,模型的充分性这一重要问题仍然存在。有一些结果拒绝和批准这种模式。这些结果是通过测试某些市场中每对股票的椭圆模型的一些性质得到的。本文证明了具有椭圆等高分布的任意一对随机变量的$\\ tau$Kendall相关系数相等和符号重合概率相等的新性质。构造了检验任何一对股票的这一性质的无分布统计检验。构建了基于个体检验的Holm多假设检验程序,并将其应用于具体年份的股市数据。本文提出了一种新的检验股票收益率分布的椭圆模型的方法。该程序适用于中国、美国、英国和德国2003年至2014年的股票市场数据。结果表明,对于美国、英国和德国的股票市场,可以接受股票收益率分布的椭圆模型假设,但对于中国的股票市场,在某些情况下却被拒绝。
