How to conduct event studies with

It is very simple to conduct event studies with the research apps of this website. You simply specify your research parameters, retrieve the data you need for the analysis, bring the data into the required structure, and upload it to the respective research app (see Figure 1). We currently offer three event study apps, or "abnormal effect calculators": The one most often used is the abnormal return calculator (ARC). For trading volume event studies, we provide the abnormal volume calculator (AVC), and for volatiltiy event studies, the abnormal volatility calculator (AVyC). The research apps are free of charge and perform for you various test statistics. You can provide your data in various different input formats, such as XLS, XLSX, and CSV - zipped or unzipped. You receive all results by email and/or website download.

What is news analytics and how to perform it?

News analytics is concerned with the quantitative analysis of news streams. It implies the procedural steps needed to turn news into quantitative metrics and time-series. News analytics allows three major applications: (1) the scientific analysis of qualitative dimensions that have previously been ignored in the study of individual events, (2) the repeated longitudinal consideration of similar sequences of events, and (3) from various practical applications, such as novel trading strategies, that build on the capability to plot firm behaviors. The figure beneath sketches the analytical framework implemented on this website (please also view this step-by-step tutorial).
