1High frequency multiscale relationships among major cryptocurrencies:portfolio management implications显示文摘This paper examines the high frequency multiscale relationships and nonlinear multiscale causality between Bitcoin,Ethereum,Monero,Dash,Ripple,and Litecoin.We apply nonlinear Granger causality and rolling window wavelet correlation(RWCC)to 15 min-data.Empirical RWCC results indicate mostly positive co-movements and long-term memory between the cryptocurrencies,especially between Bitcoin,Ethereum,and Monero.The nonlinear Granger causality tests reveal dual causation between most of the cryptocurrency pairs.We advance evidence to improve portfolio risk assessment,and hedging strategies.Walid Mensi Mobeen Ur Rehman Muhammad Shafiullah Khamis Hamed Al‑Yahyaee Ahmet Sensoy 2021Financial Innovation2021,7,1:2
