In this paper information theoretical approach is applied to the description of financial markets A model which is expected to describe the markets dynamics is presented. It is shown the possibility to describe market trend and cycle dynamics from a unified viewpoint. The model predictions...

Understanding the origins of wealth inequality is critical in the debate over what, if anything, to do about it. In this note, we propose a simple model which is still rich enough to reproduce observed patterns of wealth inequality. We call it the Concentrated Asset Betting (CAB) model. A key...

With 30% of the world's investment grade sovereign bonds trading at sub-zero yields, there is a growing acceptance that negative interest rates are the 'new normal.' Even very low probabilities of sustained negative interest rates in the future leads to incredibly high Expected Values for...

Agent-based models are usually claimed to generate complex dynamics; however, the link to such complexity has not been subject to rigorous examination. This paper studies this link between the complexity of financial time series---measured by their multifractal properties---and the design of...

This note describes the background of Factor investing in its Smart Beta form, and discusses the reasons Factor investing has become a popular investing style. We also discuss a number of reasons for skepticism regarding forward-looking expected returns

The investor sentiment measures based on market variables underperform those sentiment measures extracted from investor surveys in various applications. By purging the fundamental component out of the market-variable-based sentiment measures thoroughly, we propose a largely contamination-free...

Strategies are often analyzed without confronting quantitatively the clients' views. They also may present an overfitting problem which is detrimental to the investor and the client. In this paper, we present a new quantitative framework that enables the clients and investors alike to test their...

We examine the complexity of financial returns generated by popular agent-based models through studying multifractal properties of such time series. Specifically, we are interested in the sensitivity of the models to their parameter settings and whether some patterns emerge in the connection...

Continuously rebalanced long-short trades are similar to highly levered trades in that their PNL profile depends not only on the final distribution of return, but also on the realized co-variance structure of the asset pair. It's easily possible for both orientations of a rebalanced long-short...
