Total shareholder return (share price return)

Business Research Plus

Thomson ReutersWhen using Datastream the datatype RI (return index) includes the re-investment of dividends. The total return can be calculated from the change in the return index over the chosen time period. The basic fomula is:

Retit = ( RIit – RIit-1 ) / RIit-1  (multiply by 100 for percentage return)

The percentage return can be calculated using a Datastream formula.

For example,  PCH#( X(RI), 1M )

  • percentage change (PCH#) of
  • the series return index (X(RI))
  • over 1 month (1M) (you can have 1D for one day, 1Y for one year etc.)

This gets the return for a company when X is an equity series, for an index when X is a index series, and for a group of companies when X is a list.

If you want the percentage change in price, that is without re-investment of dividends, you can use P rather than RI,

Risk Free Rates on Datastream

Business Research Plus

A couple of business library blogs have mentioned the risk free rate recommendations on the Thomson Reuters Datastream extranet – see Risk free rates, T-Bills, Benchmark bonds (Databaser, Oct 2013) and Datastream – Risk free rate (Aberconway Library, Sept 2011). The first recommendation is to use 3 Month Treasury Bills where possible (Thomson Reuters, 2009). Unfortunately, these recommendations have not been updated recently. Some of the series mentioned are now dead (i.e. do not give up to date data), including those for the US and UK.

Thomson ReutersThere are alternative sources for 3 Month Treasury Bills (T-Bills) on Datastream:


  • USTBL3M – 03/07/1989 – 01/05/2007, Daily, US TREAS.BILL 3M(USE FRTBS3M)’DEAD from Financial Times
  • FRTBS3M – 04/01/1954 – present, Daily, US T-BILL SEC MARKET 3 MONTH from Thomson Reuters

Requesting monthly data in Datastream – what happens?

Good post on how different frequencies work in Datastream

EDSC tips & hints

In the Time Series Request in Datastream you can choose the frequency. Available options are Daily, Weekly, Monthly, Quarterly and Yearly. What happens when your serie has a daily frequency and you request the data with a monthly frequency? That depends on the datatype you request.

P and MV
When you download the closing price (P) or market value (MV) of an equity with a monthly frequency, you get data for one day of each month. Which day Datastream uses, depends on the start date entered in the request: if the start date is 1/1/2005, you get the P and MV of the first (trading) day of each month. If you enter 1/31/2005 as the start date you get the P and MV of the last trading day of each month.

Be aware: this is not a monthly average – it’s just the data on one particular day of the…

Datastream and SEDOL codes

Great post on using SEDOL codes in Datastream courtesy of the library at Manchester Business School.

Business Research Plus

Thomson ReutersTake care when using SEDOL codes in Thomson Reuters Datastream! You can lookup an equity by its SEDOL code (Datastream datatype SECD) but SEDOL codes do not work properly when creating a Datastream List or when using a Datastream Request Table.

There is a solution – add ‘UK’ before the SEDOL code, so B09LQS3 becomes UKB09LQS3, and then they are recognised correctly.

This is a known problem – see Searching Datastream using Sedol codes and Datastream Tips and tricks.

The following screenshot shows some results from a Datastream Request Table – the first five have UK added, then next five are the original SEDOL code, the next five have UK added and so on.

You will see that none of the SEDOL codes starting with “B” are recognised correctly, and some of those that are just numbers are mistaken for Datastream codes so can return data referring to something…
