How to conduct event studies with www.eventstudytools.com?
Conducting event studies with this website is very simple. It implies a short sequence of steps illustrated in Figure 1. The only step specific to conducting event studies with this website is the transformation of your data into the format required by the website's abnormal return calculators. Irrespective of whether you use the free basic (bARC) or the access-restricted advanced abnormal return calculator (aARC - beta, purchase a passkey), you need to upload three CSV-data files: One file specifying the analysis parameters (i.e., the request file) and two files holding your stock and reference index price information (example files for bARC and aARC, macro for Yahoo! Finance data retrieval, help in file construction, help in defining your research question). After uploading these files, the research app will perform your event study and prompt you results through CSV files.

What is news analytics and how to perform it?
News analytics is concerned with the quantitative analysis of news streams (e.g., Das, 2010; Kimbrough, Kimbrough et al. 2011). It also implies the procedural steps needed to turn news items into quantitative metrics and time-series. News analytics allows three major applications: (a) the scientific consideration of qualitative dimensions that have previously been ignored in the study of individual events, (b) the repeated longitudinal consideration of similar sequences of events (e.g., characterizing organizational behaviors), and (c) from a practical perspective, novel trading strategies and other practical applications that draw on the capability to plot firm behaviors (e.g., business intelligence). Figure 1 sketches the analytical framework implemented on this website (please also view this step-by-step tutorial).
