Investigation of Convergence in the Returns of Cryptocurrencies: Panel Nonlinear Tar Approach

Summary/Abstract: Purpose – The main objective of this study is to establish/offer an optimal cryptocurrency portfolio for investors. For this purpose, the existence of convergence among the daily returns of cryptocurrencies is investigated. Through this study, it is aimed to determine whether cryptocurrencies are becoming alternative tools for each other or not. Design/methodology/approach – To conduct analysis a sample that includes six cryptocurrencies that have the highest market value and transaction volumes are built. The analysis is based on the daily returns of the cryptocurrencies for the 30.10.2016-12.05.2019 period. First, the linearity of the series of cryptocurrency returns is analyzed. The convergence among daily returns of these cryptocurrencies is examined by using a panel nonlinear TAR unit root test. Findings – According to Caner and Hansen (2001) Linearity Test Results, it is found out that the return of the cryptocurrencies is not linear. Based on Beyaert and Camacho (2008) Panel Nonlinear TAR Unit Root Test Results, it is determined that there is a convergence between the cryptocurrency returns on the condition that the daily cryptocurrency returns are higher than - 5.958%.
