Study on capital market anomalies: Does machine learning help to better predict stock returns?


In a dynamic financial market, the precise prediction of share returns is a challenging task. A common approach is to utilise capital market anomalies. These include certain company characteristics that are known to influence stock returns. However, conventional linear methods often struggle with the complexity inherent in these anomalies, especially in a global sample of stock returns. A research project by scientists from Kaiserslautern and Munich has used machine learning to overcome this challenge. This novel study uses machine learning to combine information from hundreds of capital market anomalies in a global sample of stocks. Their results were presented in the renowned 'Journal of Asset Management'.

Project "Smart batch processes in the energy system of the future"

The RPTU is working on topics of the future that move society and industry. This is demonstrated by the latest success in research: RPTU has received over 5 million euros from the Carl Zeiss Foundation's "CZS Breakthroughs" programme for the interdisciplinary project "Smart Batch Processes in the Energy System of the Future". The Carl Zeiss Foundation's "CZS Breakthroughs" programme supports top international research from Baden-Württemberg, Rhineland-Palatinate and Thuringia. The chairs of "Production Management" with Prof Dr Florian Sahling and "Sustainability Management" with Prof Dr Katharina Spraul from the Department of Economics are involved.

Research profile

The research profile is initially derived from the individual profiles of the departments. In addition, interdisciplinary topics, such as sustainable corporate management, are also addressed. There are cooperative relationships with other departments, affiliated institutes and other universities, particularly in the case of third-party funded projects. With its third-party funding per professorship, the department is one of the top departments in economics.


Modelling of investment decisions under undercertainty in capital markets, as well as the investigation of the behaviour of agents with subjective expectations in OLG models.

In the context of digitalisation, various dimensions of entrepreneurship and organisational innovation are at the heart of the field. The main focus is on theory-based and empirical research into digital start-ups, innovations and forms of financing as well as the associated mechanisms of action and their management in business and society.

These topics are reflected in the three central research areas of the professorship:

  • Digital Entrepreneurship
  • Entrepreneurial Finance
  • Digital Transformation & Analytics

Research at the Chair of Business Administration, in particular External Accounting, is classified as behavioural accounting and aims to better understand the use and provision of accounting information by economic actors and the associated decisions in order to be able to make suggestions for improving decision-making in practice on this basis. This follows the basic understanding that one of the main purposes of accounting is to provide information that is useful for decision-making.

This is examined primarily against the background of current social and economic developments, such as digitalisation and the associated increasing availability of information. Exemplary questions to which the Chair's research would like to contribute are, for example: What is the mode of action of differently designed corporate communication, in light of the fact that more and more investors:inside are carrying out transactions on mobile devices? How can artificial intelligence be used to increase employee satisfaction and the effectiveness of performance incentives? What drives unethical behaviour at middle management level? Experimental research methods are used to answer these questions.
