Just wondering how people handle their share price data in charting software after a company merger.
For example, when SIG merged with AWP to give SIP, you had totally unrelated data for SIG and AWP, and then had to create data for SIP.
In such a case, would you:
- Leave SIP with just the data since the merger?
- Merge SIP with only one of SIG or AWP and ignore the other?
- Somehow merge the SIG and AWP data together to get historic data for SIP?
If you use a data provider that does all this sort of stuff for you, what did they do for that particular merger?
