At the heart of the portfolio selection problem lies the challenge of accurately estimating asset expected returns and covariance matrices. The classical Black-Litterman model addresses this challenge by combining market equilibrium and investors' views within the Markowitz mean-variance...

In the realm of investment decision-making, it is widely recognized that effective decision-making necessitates the integration of various knowledge domains. This paper presents a novel approach to estimating investors’ views in the Black-Litterman model by accumulating evidence from various...

We examine the diversification benefits of cryptocurrency asset categories. To mitigate the effects of estimation risk, we employ the Bayes-Stein model with no short-selling and variance-based constraints. We estimate the inputs using lasso regression and elastic net regression, employing the...

For 5,500 North American hedge funds following 11 different strategies, we analyse the stand-alone performance of these strategies using a stochastic discount factor approach. Employing the same data, we then consider the diversification benefits of each hedge fund strategy when combined with a...

Cryptocurrency returns are highly non-normal, casting doubt on the standard performance metrics. We apply almost stochastic dominance (ASD), which does not require any assumption about the return distribution or degree of risk aversion. From 29 long-short cryptocurrency factor portfolios, we...

We investigate the out-of-sample diversification benefits of cryptocurrencies from a generalised perspective, a cryptocurrency-factor level, with traditional and machine-learning-enhanced asset-allocation strategies. The cryptocurrency factor portfolios are formed in an analogous way to equity...
