SELECTED PUBLICATIONS & RESEARCH PROJECTS

Most of my current work evolves around business cycle research and trading models utilizing low, medium and high frequency strategies.


Current projects include:

 

  • Recurrence and Cross-Recurrence Quantification analysis of ultrahigh frequency US stock market data.

  • Application of SVMs (Support Vector Machines) on high frequency data for intradaily and daily trading strategies.

  • Trading strategies utilizing proprietary volatility indices and other market stress indicators.

Selected Works

BOOK:

  • Co-Editor: Progress in Financial Markets Research, (2012) Editors: Catherine Kyrtsou (University of Macedonia, Thessaloniki, Greece), Costas Vorlow (Director, IMAR, International Markets and Risk, Athens, Greece), New York, Nova Science, (ISBN: 978-1-61122-864-9)

Numerous empirical studies have analysed the identification and nature of the underlying process of an economic system, as well as the influence of information on financial time series. The standard financial theory of efficient markets assumes identical investors having rational expectations of future stock prices. This means that there are no opportunities for speculative profit, and both trading volume and price volatility are not serially correlated. This book approaches key topics such as the above from a novel point of view, by covering theoretical and  methodological issues ranging from time series and asset pricing methods to data mining, non-linear or chaotic dynamics and wavelet-based analysis. Order from AMAZON

BOOK CONTRIBUTIONS:

​In this work we employ the Recurrence Quantification Analysis (RQA) framework, effective in discovering evidence of non-linear determinism and complex dynamics in short, noisy and irregular signals. We apply RQA to a set of US macroeconomic time series and simulated sequences in order to provide a classification based on topological aspects of their dynamics. Through RQA we can in general obtain useful information on the quality and complexity of the structure of the dynamics in an economy, as this is embedded in its macroeconomic time series.

​The Handbook of Investors' Behavior during Financial Crises provides fundamental information about investor behavior during turbulent periods, such the 2000 dot com crash and the 2008 global financial crisis. Contributors share the same behavioral finance tools and techniques while analyzing behaviors across a variety of market structures and asset classes. The volume provides novel insights about the influence and effects of regional differences in market design. Its distinctive approach to studies of financial crises is of key importance in our contemporary financial landscape, even more so since the accelerated process of globalization has rendered the outbreak of financial crises internationally more commonplace compared to previous decades.
