In my Anlaysis report, I get "The event window seems to include an unexpected number of days the firm's stock has not been traded on" for some of my events. Could you please tell me what exactly this means?
I have two sub-sets of events, "good news" (15 events) and "bad news" (17 events), which I wish to see their effect of different sectors of the FTSE. Could you guide me into how I can test for these subsets of events on a specific sector at once?
I'm encountering difficulty with the estimation window. Most research papers I have found take a [-120;-11] estimation window with a [-1;1] event window. But in the app when I try to put in that estimation window I get an "Event Data import" error. I have seen you answer this question before saying that the estimation window needs to have one positive number. How can I use the [-120;-11] window with the app?
I'm trying to do an event study to look at the CAAR of stock prices during an M&A announcement. Some companies have had multiple announcements for different transactions. How can I put that in my data? It come back saying "Duplicate entry in event data" if I put the company name in twice. Do I need to change the name of the company? Delete duplicates? Would that not affect my results?
Can I conduct a complete event study using your app?
I'm doing my Thesis right now and I have to test if certain events at single firms do have an effect on a group of other firms all in the same market. How would you recommend me doing this? All Events seperate? I got about 200 single Events and 50 firms spread globally
I'm trying to conduct event study with two different groups. I have multiple event days and two groups. Event study tool gives me results from all the different days separately but doesn't show the grouped results in CAAR and AAR file. What could be the problem?
I intend to use intraday event studies with a sample of 1,200 profit announcements issued after the close and before the opening of the B3 stock exchange. Would you have an example of intraday event study implementation to make available (excel, R or other format)? I have read many articles on the subject however, nothing very practical. I would like to adopt some of the novel techniques for detecting jumps. If you can suggest some specific practical literature for reading.
I am carrying out an event study analysis based on Market Model for my master thesis and would like to use the EvenStudyTools Application. I have a question regarding the request file field 'Event ID'. According to the sample file an ID for various events should be introduced. In my case, I have only one event which affects 20 companies. How should I complete this field? I tried with the same event number for all the companies and it did not work because of duplicate entry in the event data. It did work though with different IDs, but I am not sure if it is correct for the same event.
And also I would like to ask regarding the field Grouping Variable. In the sample file this field is completed with an 'Addition'. What exactly should be in this field?
I am writing to you concerning the Event Study Calculator. Indeed, I would like to use this helpful tool but I am confused with two elements:
- In what code should the firm ID be? (ISIN, SEDOL, NAME...)
- For the firm and market data, how many days should we use for the returns (the example shows around 800 days which is much more than the event and estimation period)?
