This thesis examines the kind of information “informed” traders have prior to a takeover announcement using options of target firms. I find that option liquidity rises before a takeover announcement, indicating the presence of informed traders. Using 2,390 M&A events, I show that the implied volatility (IV) skew and the relative option-to-stock trading volume O/S predict negatively on target announcement returns, but that the difference between implied volatilities of calls and puts (IV spread) has no predictive power. The main results indicate that the predictive power of these three informed option trading proxies increases if target management is entrenched and if the bidder and the target are in the same industry. I conclude that informed trading is partially driven by industry insiders with specific knowledge about the future acquisition. However, the results are only significant for one or two informed option trading proxies at a time.

Zielsetzung und Themenschwerpunkte (Objectives and Key Themes)
This thesis investigates the type of information that "informed" traders possess before a takeover announcement, utilizing options on target firms. The primary objective is to determine whether option liquidity changes before a takeover announcement, suggesting the presence of informed traders. The research further examines the predictive power of various informed option trading proxies for target announcement returns and explores how deal characteristics might influence this relationship. The key themes of the research are:- Informed Trading in Options Markets
- Predictive Power of Option Trading Proxies for Takeover Announcement Returns
- The Role of Deal Characteristics in Informed Trading
- The Price Discovery Process in the Options and Stock Markets
- The Value of Mergers and Acquisitions
Zusammenfassung der Kapitel (Chapter Summaries)
- Introduction: This chapter introduces the topic of informed trading in the context of mergers and acquisitions (M&A), highlighting the importance of understanding the information possessed by informed traders. It presents the research question of this thesis: what information do informed option traders possess regarding the target firm and the deal before the takeover announcement?
- Literature Review: This chapter reviews existing literature on the value of mergers and acquisitions, the wealth effects of acquisitions, and the relationship between stock and options markets. It examines previous studies on the predictive power of option trading proxies for announcement returns, particularly focusing on the role of informed traders and their knowledge about the takeover. It explores how information asymmetry and deal characteristics affect the price discovery process.
- Data and Methodology: This chapter outlines the data sources and methodologies employed in the research. It describes the data collection process for M&A events, options, stocks, and company information. The chapter explains the methodology used to calculate cumulative abnormal returns (CARs) and the key explanatory variables, as well as the hypothesis testing procedures.
- Empirical Results: This chapter presents the empirical findings of the study. It analyzes option liquidity before takeover announcements, examining the predictive power of option liquidity proxies. The chapter further investigates the relationship between informed option trading proxies and takeover announcement returns, exploring the influence of deal characteristics.
