According to Stützel (1960), insider transactions are comparable with roulette, where corporate insiders – in contrast with regular players – have the privilege to place their chips after the ball begins to rest. In other words, certainly, the outcome of the game is well known to corporate insiders. Apart from that, focusing on capital market transactions, are corporate insiders turned out to be winners?
Due to their closeness to the business, it is said that corporate insiders possess firm-specific, non-public, and value-relevant information. Various international empirical findings support that they are able to exploit their information advantage towards market participants, so-called outsiders. Additionally, corporate insiders represent anti-cyclical abilities and they are also capable to realize price discrepancies deviating from the firm’s intrinsic value.
Is there an opportunity for market participants to benefit as well? Because of legal leeway and a lag in technical transmission, typically, outsiders are informed later about transactions in own company stocks by insiders. However, referring to existing literature, predominantly, they also benefit by imitating transactions after public announcement as long as transaction costs are ignored. Thus, capital market efficiency is violated.
Of course, this link is recognized. For instance, in 2006, in cooperation with the FIFAM Research Institute for Asset Management, Handelsblatt, and the Technical University of Aachen, the Commerzbank published an insider trend barometer displaying the ratio from purchases to sales every two weeks (Handelsblatt, 2016). Furthermore, the Commerzbank issued a certificate containing companies of the DAX30 associated with directors’ dealings (Commerzbank, 2006).
In comparison with established nations like the USA or the UK, Germany looks back on a brief history regulating insider trading; therefore, research activities are manageable. While one strand of literature concentrates on performance effects for insiders, the other strand analyzes performance effects for outsiders.
This thesis examines directors’ dealings in two ways.

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.
Excerpt from the Book
2.1 Theoretical and conceptual foundations
Generally, by purchasing or selling listed securities the term insider trading deals with the exploitation of non-publicly known price-sensitive information which is also valid for transactions on behalf of a third party or derivatives. Thus, insiders have an information advantage relative to other market participants, so-called outsiders, having the potential to generate abnormal returns exceeding market average. Stating more precisely, insider trading is specified considering the type of insider security, category of persons covered, and the specific inside information (§ 15, WpHG).
Since directors' dealings are the explicit object of investigation of the present thesis, in the following, the insider term relates to the framework of existing legislation regarding disclosure requirements of section 15a, WpHG.
At this point, it is essential to differentiate the terms insider trading and directors' dealings because at first glance, they seem to be equivalent. The expression directors' dealings can be attributed to the UK Criminal Justice Act in 1993 first using the term insider dealing. In Europe, insider trading is equated with an illegal act of trading on private information, while directors' dealings are considered as reportable legal insider trading including potential assessments on business prospects relevant to pricing. On the other hand, contemplating US law, directors' dealings are associated with illegal as well as legal operations.

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.
