Zielsetzung und Themenschwerpunkte (Objectives and Key Themes)

This study examines the relationship between returns on portfolios sorted by size, specifically focusing on the lead-lag patterns observed in European markets. The research investigates two novel factors that could explain these lead-lag effects: size distribution and market efficiency. The study aims to analyze the lead-lag structures within a framework that distinguishes between countries based on their stock market development.

• Lead-lag patterns between large and small capitalization portfolios in European markets
• The influence of size distribution and market efficiency on lead-lag effects
• Comparison of lead-lag structures in emerging and developed economies
• Identifying the underlying determinants of lead-lag patterns
• Assessing the impact of market inefficiencies on lead-lag effects

Zusammenfassung der Kapitel (Chapter Summaries)

• Introduction: This chapter sets the stage by discussing the predictability of short-term stock returns, highlighting the concept of lead-lag effects, particularly those driven by size differences. It outlines the study's focus on size-driven lead-lag patterns in both emerging and developed European markets, along with the exploration of new causal factors, size dispersion, and market efficiency.
• Literature Review: This chapter provides a detailed overview of existing research on lead-lag effects in developed countries, highlighting the consistent finding that large capitalization stocks lead the returns of small capitalization stocks. It explores various rationales for these size-based lead-lag effects, including information adjustment speed, financial transparency, market imperfections, and other explanations.
• Methodology: This chapter outlines the methodology employed in the study, including country-by-country regressions, the measurement of speed of adjustment, market efficiency, and size distribution. It explains the use of pooled regression to analyze the determinants of lead-lag patterns.
• Data: This chapter presents the data used in the study, providing details about its sources and characteristics.
• Results: This chapter presents the findings of the study, including the results of country-by-country regressions and the pooled regression. The analysis focuses on identifying the underlying determinants of lead-lag patterns and exploring the impact of size distribution and market efficiency.
