The current members of an equity index can be found in Bloomberg, Datastream or LSEG Workspace.  

- Bloomberg (available at Barcelona Library Financial room)

First, you need to find the right Bloomberg ticker for the equity index. In the Bloomberg search bar, type ‘SECF<GO>’ (that is, SECF then the Enter key) to use the Security Finder. Choose Category: Index/Stats and Sub-Category: Equity Index. If the index you need does not already appear in the list, you can further filter the list by typing the name of the index in the description field. 

On the first column, you have the Bloomberg ticker of the index. Click on the index you want and a menu will appear, choose Member Weightings (MEMB).

You can get straight to the Member Weightings screen if you know the Bloomberg ticker for the index. Type, for example, ‘SPX <Index> MEMB <GO>’ (that is, SPX then the F10 key then MEMB then Enter).

The date can be changed in the ‘As of’ box at the top-right and extra columns can be added.
From here, on the red menu, click Export > Excel to export the data

Alternatively, you can use Bloomberg formula in Excel to retrieve the members. Here is the formula for your reference:


 Syntax: =BDS(“ticker”; “field”; “overriding field=YYYYMMDD”)

The Excel will retrieve only the Bloomberg tickers of the members of the index as of that date. If you want to have the name of the company in the Excel, you need to use a separate BDP formula to pull the name.  =BDP (A1 & “ Equity”; “NAME”) apply this to the first cell and drag down to apply to the remaining tickers. You can use the same syntax to pull other data, for example the last price: =BDP (A1 & “ Equity”; “PX_LAST”). (Note that there is a space before the word “Equity”

Datastream (available at Barcelona and Madrid Libraries through LSEG Workspace (formerly Refinitiv Workspace). Ask staff for password.)
