Objectives & Core Themes

This master thesis investigates the performance effects of directors' dealings in Germany to assess market efficiency and identify potential strategic trading patterns among corporate insiders. By applying an event study approach to a comprehensive dataset spanning from 2004 to 2014, the research examines whether insiders can generate abnormal returns and if outsiders can benefit by mimicking these transactions.

• Testing of the Efficient Market Hypothesis (EMH) in Germany.
• Analysis of corporate insider trading motives and performance.
• Comparison of insider performance between transaction and reporting days.
• Investigation of strategic patterns (contrarian/anti-cyclical behavior).
• Impact of firm-specific factors (size, volume, insider position) on abnormal returns.

Frequently Asked Questions

What is the core focus of this thesis?

The work focuses on analyzing directors' dealings in Germany to determine if insiders possess an information advantage that allows them to generate abnormal returns and if this behavior challenges the Efficient Market Hypothesis.

Which research methodology is applied?

The thesis utilizes a quantitative event study approach to measure abnormal returns around specific transaction and reporting dates, complemented by multivariate OLS regression analysis.

Does the thesis differentiate between insider groups?

Yes, the study distinguishes between members of the executive board, the supervisory board, and other insiders to test the information hierarchy hypothesis.

What are the primary goals regarding market efficiency?

The primary goal is to test the strong form of the EMH using transaction day data and the semi-strong form using reporting day data, while also exploring if outsiders can profit from public disclosures.

What key findings does the study present?

The findings indicate that insider purchases are associated with positive abnormal returns, while sales often lead to negative abnormal returns, suggesting that markets do not fully reflect this information immediately.

How does the German market compare to the US and UK?

The thesis highlights that Germany had a later start in regulating insider trading compared to the US and UK and is characterized by a bank-dominated system, which influences corporate governance and disclosure practices.

What role does transaction volume play in the analysis?

Transaction volume is analyzed to see if larger trades contain higher information content, with the study testing if higher volume correlates with greater abnormal returns.

What is the significance of the "post-crisis" sub-sample?

The post-crisis sub-sample analysis helps identify if market reactions to insider trades changed following the financial crisis of 2009, revealing that performance effects were often more pronounced after the crisis.
