Acknowledgements<br />

I s<strong>in</strong>cerely thank my advisor, Pr<strong>of</strong>essor Walter Zucch<strong>in</strong>i, for the encouragement and the<br />

academic support he provided to me as an external doctoral student over the last few<br />

years. Besides, I am grateful to Pr<strong>of</strong>essor Jörg Breitung for supervis<strong>in</strong>g my work on<br />

time-vary<strong>in</strong>g sector betas and for allow<strong>in</strong>g me to participate <strong>in</strong> his econometrics course<br />

at the Bonn Graduate School <strong>of</strong> Economics dur<strong>in</strong>g the w<strong>in</strong>ter semester 2004–2005. I am<br />

<strong>in</strong>debted to both <strong>of</strong> them for their commitment, their helpful comments and the many<br />

valuable suggestions they made <strong>in</strong> the <strong>in</strong>sightful discussions we had.<br />

Thanks to my former colleagues at Generali Investments, Cologne, where I spent<br />

the first three years <strong>of</strong> my doctoral project. After my first year as a fund manager <strong>in</strong><br />

the equity department, the idea <strong>of</strong> gett<strong>in</strong>g some more academic work done arose. I<br />

am especially thankful to Michael Fuchs for his belief <strong>in</strong> me, to Dr. Stephan Stockert<br />

and the management board for creat<strong>in</strong>g a framework that enabled me to work<br />

on the thesis and on equity strategy at the same time, and to my friend He<strong>in</strong>z-Josef<br />

Stenten who has always been there for some thoughts away from econometrics. I also<br />

appreciate the support provided by Quoniam Asset Management dur<strong>in</strong>g completion<br />

phase <strong>of</strong> the project.<br />

Many thanks go to Dr. Jan Bulla for his contribution <strong>of</strong> the code to conduct the<br />

computations related to hidden Markov <strong>models</strong>, for answer<strong>in</strong>g all my LaTeX-related<br />

questions and for read<strong>in</strong>g the f<strong>in</strong>al manuscript.<br />

I would like to thank my family and all my friends for their support and their patience<br />

with me. My special thanks go to Levent and Alper Özkurt for giv<strong>in</strong>g me shelter dur<strong>in</strong>g<br />

my numerous stays <strong>in</strong> Gött<strong>in</strong>gen. I am <strong>in</strong>debted to my mom for allow<strong>in</strong>g me to follow<br />

this route and for always be<strong>in</strong>g there.<br />

F<strong>in</strong>ally, my heart goes to my wife, Leyla, who conv<strong>in</strong>ced me that there is no alternative<br />

to start<strong>in</strong>g this project, and who has always kept faith <strong>in</strong> me. I very much enjoyed<br />

our discussions on conceptual issues and her <strong>in</strong>genious contributions on how to move<br />

forward methodologically. Without her love and <strong>in</strong>spiration, her cont<strong>in</strong>uous support and<br />

dedication, it would not have been possible for me to get this thesis together.<br />
