DFIH develops an infrastructure to collect, align and share data on all the assets traded on the French stock markets and listed issuers over the 19th and 20th centuries. It registers twice per month spot, forward and options prices of securities, currencies and precious metals, besides securities events relevant for harmonizing prices over time. It records information on issuers such as boards, headquarters, balance sheets and income statements. It aims at broadening its scope to include a larger variety of data. To achieve its goals, it contributes to the development of innovative technologies of data extraction.
Research projects based on DFIH have been financed by ANR and PSL University. The database is exploited by several researchers in France and abroad.
