Bulgarian Stock Exchange (BSE) announced that it will partner with Refinitiv, a leading provider of data and infrastructure for financial markets and a member of the London Stock Exchange Group. Refinitiv will manage and provide data on the sustainable performance of BSE listed companies in the form of ratings, which will serve to qualify constituents that will be included in the BSE’s upcoming ESG Index. The methodology for the new stock exchange index is expected to be approved by the end of the year.
