Post-Earnings-Announcement Drift

Stock prices tend to adjust slowly to the information contained in earnings announcements. After a positive (negative) earnings surprise (defined as the difference between actual and expected earnings), stock prices tend to drift upward (downward) for up to one year. This phenomenon is referred to as the post-earnings-announcement drift (PEAD). This project's main contribution to research into PEAD is the use of laboratory experiments. In three separate papers, the project will investigate (1) the most prominent explanation from the literature for why PEAD occurs - earnings autocorrelation, (2) whether limits to arbitrage prevent the elimination of PEAD, and (3) how share prices adjust to the information contained in the announcements, and how institutional features of the market, details of trader behavior and the timing of the earnings announcement affect the adjustment of prices.

Regulation of Insider Trading

This project studies the impact of insider trading on markets. The topics under research include how insiders' presence and trading activity influence the efficiency of prices, the profitability of insiders' and non-insiders’ investments, how insider regulation affects these relationships and how regulators can detect insiders.

Financial Market Microstructure

This project studies the way securities are actually traded on financial markets with a special focus on market liquidity and efficiency. The main research areas include: (i) An in-depth analysis of the liquidity of the Austrian stock market, based on “Finance Research Graz Data Services” (FiRe Graz DS) – Link: banken-finanzierung.uni-graz.at/de/datenbank-finance-research-graz-data-services-fire-graz-ds/ (ii) Algorithmic and high-frequency trading, (iii) Market reactions to news.

Funding: Partly funded by the Anniversary Fund of the Austrian National Bank (OeNB)

Blockchain Finance and Cryptocurrency Markets

This project which is interdigitated with the former studies cryptocurrencies as a new asset class and focuses on the different channels these currencies can be transferred (on-chain versus off-chain). The main research areas include: (i) Price efficiency and liquidity on cryptocurrency trading platforms, (ii) Microstructure of crypto-markets, (iii) Interdependences between on-chain and off-chain trading of cryptocurrencies

Bank Risk Governance

Studying bank risk governance is particularly relevant given the ongoing debate on whether bank governance failures caused the recent financial crisis. Therefore, this project focuses on bank risk governance, which differs substantially from non-bank governance, and its interplay with banking regulation. Several dimensions of this interplay are studied. First, money laundering infractions of internationally active banks are employed to study when and how these infractions are affected by local and foreign regulators. Second, banks in dual banking countries are used to investigate how the introduction of banking regulations, especially with respect to the Basel disclosure requirements, affects banks’ risk governance structures.

Risks in International Banks

Large, internationally active banks play a special role in the (international) financial system because they are closely connected to their governments due to large sovereign bond holdings and because they transmit shocks easily from one country to another. This project focuses on several roles that internationally active banks may play in the financial system. First, sovereign rating downgrades are used to test whether banks spill over shocks from one country to another through their various types of foreign asset holdings, such as foreign sovereign debt holdings and foreign claims to banks. Second, the most recent COVID crisis is used to investigate how the change in banks’ risk profile is moderated by their governments’ creditworthiness due to the guarantee channel which is in place between banks and governments.
