Many authors have already studied about stock price reactions after earnings announcements yet, which is because of the importance of earnings announcements, in particular quarterly earnings announcements, for many investors. However, all major studies concerning this topic deal with long-term scenarios, the stock’s price performance is measured for a time period of at least three quarters. Due to the fact that there are many investors, especially institutional investors such as hedge funds that trade stocks much more frequently, the existing studies are not relevant for them.
This paper studies stock price reactions around quarterly earnings announcements for companies listed in Deutscher Aktienindex (DAX) or Midcap DAX (MDAX) with respect to changes of the company’s full-year outlook and of earnings surprise regarding analyst consensus forecast within ten days before and after the announcement date. Hence, this paper aims to analyse short-term reaction to quarterly earnings announcements, which are of relevance for all investors, whose investment strategy is, at least partially, focussing on the short-term performance. The main target group of this analysis are therefore hedge funds and investors that run short-term strategies. Due to the fact that the widespread Event Study Methodology is focused on the long-term, it is irrelevant for this analysis.

Research Objectives and Key Topics
This paper examines short-term stock price reactions to quarterly earnings announcements for companies listed in the DAX and MDAX indices. It aims to determine how market participants react to deviations from analyst consensus forecasts and changes in corporate full-year outlooks, specifically addressing the needs of investors running short-term strategies like hedge funds.
- Analysis of market efficiency versus behavioural finance theories in the context of earnings reports.
- Evaluation of abnormal returns across nine distinct portfolios based on analyst expectations and outlook guidance.
- Comparison of market reactions between bull and bear market scenarios.
- Impact assessment of pre-announcement stock performance on post-announcement price behavior.
- Identification of outliers, including the role of profit warnings and short-selling activities.
Excerpts from the Book
1.1 Problem Definition and Objectives
“The impact of particular types of firm-specific events (e.g. […] earnings reports) on the prices of the affected firms’ securities has been the subject of a number of studies. A major concern […] has been to assess the extent to which security price performance around the time of the event has been abnormal – that is, the extent to which security returns were different from those which would have been appropriate, given the model determining equilibrium expected returns.” (Brown and Warner, 1980, p. 205).
Many authors have already studied about stock price reactions after earnings announcements yet, which is because of the importance of earnings announcements, in particular quarterly earnings announcements, for many investors.

Summary of Chapters
1 Introduction: Defines the research problem regarding short-term stock price reactions to quarterly earnings reports and outlines the study's scope for DAX/MDAX companies.
2 Theoretical Foundations: Covers stock price determinants, legal obligations for Prime Standard companies, market efficiency hypotheses, and the theory of anomalies.
3 Theoretical Discussion on Stock Price Behaviour after Earnings Announcements: Explores behavioural finance models, judgement biases like conservatism, and investment strategies that challenge the Efficient Market Hypothesis.
4 Practical Examination on Stock Price Behaviour after Earnings Announcemens: Details the empirical methodology, data collection, portfolio classification based on consensus and outlook, and presents the results of the stock performance analysis.
5 Conclusion: Summarizes the study's findings on the crucial influence of consensus surprises and outlook changes, concluding that both factors similarly impact short-term stock price movements.

Frequently Asked Questions
What is the core focus of this research?
The research focuses on the short-term impact of quarterly earnings announcements on the stock prices of companies listed in the German DAX and MDAX indices.
What are the primary themes addressed in this study?
The central themes include the influence of analyst consensus expectations, the impact of management's full-year outlook, market efficiency versus behavioural finance, and the role of pre-announcement performance.
What is the main objective of the paper?
The primary goal is to provide actionable insights for short-term investors and hedge funds by analyzing how stock prices react to specific earnings-related news within a ten-day window surrounding the announcement.
Which scientific methodology is employed?
The study uses an event-study approach, separating companies into nine portfolios based on earnings surprise (above/at/below consensus) and outlook guidance (raised/unchanged/lowered), further differentiating between bull and bear market scenarios.
What is covered in the main body of the work?
The main body establishes the theoretical foundations of market efficiency and behavioural finance, followed by a detailed practical examination of 155 quarterly earnings announcements to identify patterns in stock price adjustments.
Which keywords best describe this research?
Key terms include Stock Price Reaction, Quarterly Earnings Announcements, Market Efficiency, Behavioural Finance, Analyst Consensus, and Portfolio Strategy.
How does the author define an 'abnormal' return in this context?
Abnormal returns are defined as the difference between the observed return of a security and the return that would have been expected given a specified model for determining equilibrium returns.
Why did the author differentiate between bull and bear markets?
The author found that market participants' behavior shifted significantly during the transition to a bear market, often leading to a "sell on good news" strategy as investors prioritized profit realization due to market insecurity.
What role do 'outliers' play in the findings?
Outliers, such as companies that met expectations but still saw price declines due to disappointing orders or profit warnings, help illustrate that market sentiment is often influenced by factors beyond simple earnings beats, such as trust and management guidance.
What is the significance of the "Pre-Announcement Performance"?
The analysis indicates that the stock's price trend in the ten days leading up to an announcement significantly influences the post-announcement reaction, serving as an indicator for optimal entry or exit strategies.
