This paper investigates persistence in high-frequency, intraday data (and also daily and monthly ones) in the case of the EuroStoxx 50 futures over the period from 2002 to 2018 (720 million trade records) using R/S analysis and the Hurst exponent as a measure of persistence. The results indicate...

This paper attempts to find evidence for sign asymmetry of exchange rate exposure. An extended classification of the sources of asymmetry has been introduced in place of somewhat incomplete classification suggested by previous studies. In addition, a new measure is suggested in order to estimate...

This paper uses time-varying second moments to investigate exchange rate exposure betas. Using a BEKK-GARCH(1,21)-M model, time-varying exchange rate exposure betas are obtained with explicit focus on the non-orthogonality between exchange rate changes and market returns. We look into certain...
