When we launched the call for papers for this special issue in November 2018, we could hardly imagine what state the World would be in, just two years later, when writing this editorial for the completed work in November 2020. In some ways, the current Covid-19 pandemic shows the necessity for the methods and results outlined in 15 highly creative and innovative papers that have been retained. What we are witnessing is a prime example for nonlinear dynamics at work. It goes without saying that adequate risk management methods have been and remain of utmost importance for navigating through the financial markets during the turbulent year of 2020. We are happy and proud to bring a wide array of state-of-the-art research to the reader written by diverse author teams. A clear focus of the special issue can be found in the application of machine learning techniques that are recurrent topics in the special issue’s articles. Equally, the theme of cryptocurrencies and their dynamics emerges. Finally, the papers also cover macro-economic topics such as Brexit, the behavior of bond markets and sovereign credit ratings. The selected papers have strong ties to twomajor finance conferences that have established andproven themselves over the years. Firstly, our issue features reworkedpapers from the 25th International Conference on Forecasting FinancialMarkets that was organized in cooperation with theOxford-Man Institute ofQuantitativeFinance and tookplace inSaidBusinessSchool, University of Oxford. Secondly, the issue includes publications from the 2018 Vietnam Symposium on Banking and Finance that took place in the wonderful old imperial capital city of Hue, Vietnam, and that was co-organized by the Association of Vietnamese Scientists and Experts (AVSE Global) and the Hue College of Economics. We firmly believe that the special issue’s papers, written by some of the leading experts in the field of nonlinear dynamics, complexity, and machine learning in finance, will be of wide interest to academic researchers and finance professionals alike. Their methodologies and findings may also encourage further research in a variety of challenging issues for the global financial markets associated with not only a post-Covid but also a post-Brexit environment.
