Cryptocurrencies, Diversification and the COVID-19 Pandemic

MPRA Paper from University Library of Munich, Germany

Abstract: The paper features an analysis of cryptocurrencies and the impact of the COVID- 19 pandemic on their effectiveness as a portfolio diversification tool. It does so by exploring the correlations between the continuously compounded returns on Bitcoin, Ethereum and the S&P500 Index, using a variety of parametric and non-parametric techniques. These methods include linear standard metrics such as the application of ordinary least squares regression (OLS) and the Pearson, Spearman, and Kendall's tau measures of association. In addition, nonlinear, non-parametric measures such as the Generalised Measure of Correlation (GMC), and non-parametric copula estimates are applied. The results across this range of measures are consistent. The metrics suggest that whilst the shock of the COVID-18 pandemic does not appear to have increased the correlations between the crypto currency series, it does appear to have increased the correlations between the returns on crypto currencies and those on the S&P500 Index. This suggests that investment in cryptocurrencies is not likely to offer key diversification strategies in times of crisis, on the basis of evidence provided by this crisis
