Getting data on all UK companies except one sector in Datastream
A common request in Thomson Reuters Datastream is to get all the companies in a particular country except for a few sectors. Previously, the Criteria Search function provided an easy way to this. Since Criteria Search is being phased out (it is not compatible with Internet Explorer 11), we have been looking at alternative approaches to some of these data requests. This example shows you one.
New request table
In this example, I have chosen the list WSCOPEUK which is a contituent list of all active, dead and delisted UK companies (over 5,000 in size). You may wish to try this approach out with something smaller first, such as LFTSE100 for the constituents of the FTSE 100 index.
The Request Type is TSL (time series for a list) and the Datatype is WC04225 (Extraordinary Items), from 01/01/2013 to 01/01/2015. The trick here is to choose Transpose and to include a custom header of the static datatype INDM4, which is the Level 4 Industry Name, with DS Code and Name as optional extras (so Format is HRCTF:INDM4,DSCD,NAME).
Custom headers were introduced in a previous post. Again, try this out with a small date range before you are happy with the output format.
Insert Excel table
Select the output results worksheet Sheet1.
Assuming you used Transpose in the Datastream request, there will be a row containing the headers such as Name, Industry Level 4 Name, DS Code and each date period (2013, 2014 and 2015 in this case). You can filter out certain rows by selecting the data from this row to the last row with content and choosing Insert > Table from the Excel menu (and tick “My table has headers”). Here, I selected cells A4 to G5331.
A filter icon appears at the top-right of every column. Click it in the industry column and untick the industry you wish to exclude (e.g. Financial Services(4)). Assuming you have the DS Code variable, you can now select cells from that column to create a new list and continue your research.
Datastream has a Worldscope constituent list for companies (equities) in most countries except the United States (which would be too large a list to use). These can be found in the Datastream Navigator by typing WSCOPE in the simple search box. A different industry classification may be required for some countries.
