Company ownership data
There have been several recent articles in the financial press on the impact of the Qatari stake in Xstrata on the outcome of the proposed merger of Glencore and Xstrata.
There have also been several questions about the resources that we have for ownership data (shareholders). We have updated the FAQ questions:
- Where can I find the institutional holdings of various stocks?
- Where do I find info on insider holdings and insider trading?
- Where can I find info on share ownership of UK stocks (shares)?
While some shareholder information is publicly available, since large shareholders and directors have to declare dealings to the markets it is not easily available in a research-friendly format.
The commercial providers of ownership data tend to provide data for users who are interested in the current ownership of a single company or a small portfolio. They also collect data from as many sources as possible: large shareholders who have to report their holdings, institutional owners who report the largest holdings in their funds, and director dealings that can be large or small. (The exception if the Thomson Reuters database in WRDS (Wharton Research Data Services) - this is more research-friendly but only covers US companies.)
With ownership data researchers need to carefully check what is available and how easily it can be collected.
