- Bloomberg (available at Barcelona Library Financial room)

Getting the membership for the start date and the end date in your range will obviously not consider any company that joined and left in the intervening time. It is common to collect the membership at month end for each month in the range, paste the results into one long list in Excel then use the Data > Remove Duplicates function to get a tidy list of each company once only.

(1) Export each month’s constituents
See FAQ Where can I find current constituent lists for the S&P and other indices?

(2) Copy and paste the Tickers into one long column for all months

(3) Select that column and choose Data > Remove Duplicates.

You can get all the other data again using the Bloomberg Excel add-in if you wish (with formulas such as =BDP (“AAPL US Equity”, “ID_ISIN”) where the first parameter is a reference to the cell with the Ticker).

There is a screen in Bloomberg called Historical Index Member Changes CHNG. But only works for some indices and the report cannot be exported.

For the FTSE 100, type ‘UKX <Index> CHNG <GO>’. Choose the date range and click the top ‘Enter 1<GO> to generate report’. A report will be generated and it will tell you the number of the report. Go to the Retrieve Reports screen RPT. View these on screen or save one page at a time to an image or printer.
