共同跳跃影响货币市场的相关性吗?

Do co-jumps impact correlations in currency markets?

Jozef Barunik, Lukas Vacha

摘要:

我们量化了共同跳跃如何影响货币市场的相关性。为了从协跳中分离出二次协变的连续部分,并研究协跳对相关性的影响,我们提出了一种新的基于小波的估计。所提出的估计框架是能够本地化的协同跳跃非常精确地通过小波系数,并确定统计上显着的协同跳跃。实证结果揭示了亚洲、欧洲和美国交易时段的共同跳跃行为的不同。重要的是,我们的文件,共同跳跃显着影响货币市场的相关性。

英文摘要:

We quantify how co-jumps impact correlations in currency markets. To disentangle the continuous part of quadratic covariation from co-jumps, and study the influence of co-jumps on correlations, we propose a new wavelet-based estimator. The proposed estimation framework is able to localize the co-jumps very precisely through wavelet coefficients and identify statistically significant co-jumps. Empirical findings reveal the different behaviors of co-jumps during Asian, European and U.S. trading sessions. Importantly, we document that co-jumps significantly influence correlation in currency markets.
