The EDSC offers two tools you can use to download company data that matches to a specific date. This can be useful for an event study and that's why one of those tools even calculates CAR's. We want to thank Arco van Oord and Dan Zhang (former EDSC members) for the development of these tools!
The Event Study Tool enables you to do an event study with DataStream data (i.e. not limited to US companies: Eventus software uses data from CRSP and is thus limited to US companies). This tool works like the Matching Tool, but after matching Datastream data with event dates, (abnormal) returns are calculated for you. Click here to download the manual.
The Matching Tool downloads data from DataStream and matches this data to a specific date per company. You can use this tool for example to download the share price on the announcement day of a merger - this day will vary by company. The manual is included in the file. Please note: this tool will not calculate returns. You need the Event Study Tool for that.
