There is a whole ecosystem around data, bringing together the key players who acquire, process, centralize and disseminate information for institutional investors, analysts and managers. The latter are extremely heterogeneous, hence the need to centralize them: stock market prices, quotation history, economic statistics, official publications, agency dispatches and financial data; all this data comes from these key players with very different jobs.

This thematic list refers to companies that play a leading role in the processing of financial data, operating in various sectors such as professional information providers, rating agencies, and trading platforms.
