This study deals with the issue whether gold actually exhibits the function of a hedge or a safe haven as often referred to in the media and academia. In order to test the Baur and Lucey (2010) hypotheses, we contribute to the existing literature by the augmentation of their model to a smooth...

This study adopts a copula wavelet approach to analyze dynamics of the gold price against bonds, stocks and exchange rates based on disaggregation of the underlying relationships across different frequencies. We also examine whether gold prices are directly affected by changes in uncertainty....

Decisions on ass et allocations are often determined by covariance estimates from historical market data. In this paper, we introduce a wavelet-based portfolio algorithm, distinguishing between newly embedded news and long-run information that has already been fully absorbed by the market....

We study the statistical properties of the Bitcoin return series and provide a thorough forecasting exercise. Also, we calibrate state‐of‐the‐art machine learning techniques and compare the results with econometric time series models. The empirical assessment provides evidence that the...
