How is it possible to find out about the differences between two stocks of the same company? For instance how can I find out what the difference between SEHK:1211 and szse:002594 is?
A little more background:
Looking at the wikipedia page for BYD (https://en.wikipedia.org/wiki/BYD_Company) I found that the company is traded as SEHK:1211 and szse: 002594. As of today the stock price for SEHK:1211 is
The currency exchange rate is 1CNY=1.16HKD. So the two stocks are seemingly different. Even their charts are noticeably different over a 5 year period (and it doesn't seem to be currency fluctuation).
The answer to the question For a single company listed in multiple exchanges in different countries, are the shares being offered the same? was very intersting, but it doesn't answer how to identify the differences. How would I know if the stock is an ADR? Or a Globally Registered Share? Or a dual listing?
Thanks a lot
