Back in 2020 I started to compile and share financial data in dataverse. The data covers corporate finance events from the DFP and FRE systems. The available tables are the same I use for my research and teaching material, and will be updated once a year. Today I updated all datasets. The available data are: R Package Source of Data Description Direct Link Last Update GetTDData Tesouro Nacional Prices and yields of brazilian sovereign bonds Link 2023-04-18 GetFREData CVM Corporate dataset from FRE systems Link 2023-04-18 GetDFPData2 CVM Annual Financial Reports from DFP system Link 2023-04-18
