英文摘要:
We find a nonlinear dependence between an indicator of the degree of multiscaling of log-price time series of a stock and the average correlation of the stock with respect to the other stocks traded in the same market. This result is a robust stylized fact holding for different financial markets. We investigate this result conditional on the stocks\' capitalization and on the kurtosis of stocks\' log-returns in order to search for possible confounding effects. We show that a linear dependence with the logarithm of the capitalization and the logarithm of kurtosis does not explain the observed stylized fact, which we interpret as being originated from a deeper relationship.

中文摘要:
我们发现股票对数价格时间序列的多尺度程度指标与该股票相对于同一市场中交易的其他股票的平均相关性之间存在非线性依赖关系。这一结果是针对不同金融市场的一个强大的程式化事实。为了寻找可能的混杂效应,我们在股票资本化和股票对数收益峰度的条件下研究了这一结果。我们表明,与资本化对数和峰度对数的线性依赖关系不能解释观察到的程式化事实,我们解释为源自更深层次的关系。
