Portfolio selection and risk management are very actively studied topics in quantitative finance and applied statistics. They are closely related to the dependency structure of portfolio assets or risk factors. The correlation structure across assets and opposite tail movements are essential to...

We analyse a sample of funds and other securities each assigned a total rating score by an unknown expert entity. The scores are based on a number of risk and complexity factors, each assigned a category (factor score) of Low, Medium, or High by the expert entity. A principal component analysis...

We employ the stochastic dominance (SD) approach that utilizes the entire return distribution to rank the performance of exchange-traded funds as traditional mean-variance and CAPM approaches may be inappropriate given the nature of non-normal returns. We find second and third-order stochastic...

Bai, et al. (2011c) develop the mean-variance-ratio (MVR) statistic to test the performance among assets for small samples. They provide theoretical reasoning to use MVR and prove that our proposed statistic is uniformly most powerful unbiased. In this paper we illustrate the superiority of our...

This is the Preface written jointly with Paul Schulte giving an overview of the current landscape in the ABCD, 5G and Quantum. There are discussions of how AI, Blockchain, Cloud Computing and Data Analytics that help both the USA and Chinese tech giants to garner a substantial portion of the...
