高频金融数据的复相关方法

Complex Correlation Approach for High Frequency Financial Data

Mateusz Wilinski, Yuichi Ikeda, Hideaki Aoyama

摘要:

我们提出了一种新的方法,允许计算希尔伯特变换为基础的复杂的相关性不均匀间隔的数据。该方法特别适用于金融界特别感兴趣的高频交易数据。其最重要的特点是能够考虑到不同尺度上的超前-滞后关系,而无需事先知道它们。我们还提出了结果,同时使用这种方法在东京证券交易所的日内报价。我们发现,个别行业和子行业往往会形成重要的市场成分,可能会遵循彼此小,但显着的延迟。这些成分可以通过分析日经225股票的复相关矩阵的特征向量来识别。有趣的是,扇形分量也被发现在对应于批量本征值的本征向量中,传统上被视为噪声。

英文摘要:

We propose a novel approach that allows to calculate Hilbert transform based complex correlation for unevenly spaced data. This method is especially suitable for high frequency trading data, which are of a particular interest in finance. Its most important feature is the ability to take into account lead-lag relations on different scales, without knowing them in advance. We also present results obtained with this approach while working on Tokyo Stock Exchange intraday quotations. We show that individual sectors and subsectors tend to form important market components which may follow each other with small but significant delays. These components may be recognized by analysing eigenvectors of complex correlation matrix for Nikkei 225 stocks. Interestingly, sectorial components are also found in eigenvectors corresponding to the bulk eigenvalues, traditionally treated as noise.
