How to determien Peer Groups on own criteria

Hi Refinitiv Developer Community,

I am working with a list of ~450 companies (primarily listed firms) and would like to retrieve, for each company, a list of peer companies — ideally 5 to 10 — using the Refinitiv Eikon or Workspace Python API.

In the Workspace platform, I know the “Peers” tab in the GUI and the PEERS() Excel formula provide these peer groups based on Refinitiv’s classification and market data.

I am looking for the programmatic equivalent (based on own criteria):

Is there a way to to do selection logic — e.g., based on TRBC industry, market cap proximity, region — using the Screener API or via a parameterized get_data() call?
Can this be done in bulk, i.e., iterate through my list of RICs or ISINs and fetch peers per firm?

Ideally, I’m looking for either:

A way to construct a screener query dynamically for each company (e.g., TRBC = X, ±30% market cap, same country).

Any guidance, and especially working coding examples would be great.

Best regards,

Hello @Bjoern

There are couple of articles on the developers forum which discuss peer analysis and demonstrate using code snippets. Please take a look at these -

@Gurpreet Thank you - but this is more discussing the existing peer function. How can specific companies be filtered/found based on a list of criteria (e.g., via screener?)?

This could be the screener or search API.

For the screener, you need to contact the helpdesk via LSEG Support for the screener formula. You can ask for the screener formula that can be used in the Workspace Excel. Then, the same formula can be applied to Python, as mentioned in this article: Find Your Right Companies with SCREENER | the Data Library (Python).

For the search API, you can refer to the following articles.
