Research Objectives and Core Topics

This thesis aims to determine how the acquisition of voting blocks by different types of acquirers influences the market valuation of German firms. By analyzing a comprehensive dataset of block acquisitions, the research investigates whether specific blockholder identities—such as banks, hedge funds, or corporations—generate distinct value effects, moving beyond the traditional focus on block size alone.

• Analysis of the relationship between shareholder structure and firm valuation in Germany.
• Evaluation of value effects based on distinct blockholder types using event-study methodology.
• Investigation of the impact of block magnitude on corporate governance and valuation.
• Comparison of market reactions to acquisitions by institutional vs. non-institutional investors.
• Examination of the "effective control" threshold and its implications for firm performance.

Frequently Asked Questions

What is the primary objective of this research?

The research aims to clarify how different types of block acquirers influence the market value of German firms, specifically testing if the identity of the blockholder matters more than the mere size of the acquired stake.

What are the central thematic fields covered?

The study centers on corporate governance, shareholder structures, the legal environment for stock acquisitions in Germany, and the empirical measurement of abnormal stock returns.

What methodology is used to evaluate the valuation effects?

The author employs an event-study methodology, utilizing an OLS market model adjusted for daily returns, and applies standardized cross-sectional tests to determine abnormal returns.

What does the main body of the work address?

The main body focuses on the empirical analysis of block acquisitions, segmenting the data by acquirer groups (banks, hedge funds, etc.) and block size thresholds, while contextualizing these results within existing corporate governance literature.

Which key groups of blockholders are analyzed?

The study examines mutual funds, corporations, banks, individual investors, insurance companies, hedge funds, and private equity firms.

What are the primary findings regarding bank involvement?

The research finds that block acquisitions by banks in Germany are associated with a negative value effect, potentially reflecting creditor interests rather than shareholder value maximization.

How do hedge funds affect firm value according to the study?

Hedge fund block acquisitions exhibit a strong positive valuation effect, with a cumulative abnormal return of 4.38% in the observed period.

What role does block magnitude play in firm control?

The study analyzes block sizes from 3% to 30%, suggesting that thresholds around 10% and 25% are critical for exercising influence and "effective control" over target companies.
