We investigate any similarity and dependence based on the full distributions of cryptocurrency assets, stock indices and industry groups. We characterize full distributions with entropies to account for higher moments and non-Gaussianity of returns. Divergence and distance between distributions...

Rényi entropy criterion, which summarizes the uncertainty in portfolio returns. Assuming asset returns are projected by a … regime-switching regression model on the two market risk factors, we develop an entropy-based dynamic portfolio selection … empirical Sharpe and return to entropy ratios, the dynamic portfolio under the proposed strategy is much improved in contrast …

Financial data are expensive and highly sensitive with limited access. We aim to generate abundant datasets given the original prices while preserving the original statistical features. We introduce the Wasserstein Generative Adversarial Network with Gradient Penalty (WGAN-GP) into the field of...
