CVM informe diário API — daily fund NAV and flows
Informe diário is the daily pulse of the Brazilian fund industry: net asset value, subscriptions, redemptions and shareholder counts, reported per fund per business day. It is the series you need to know whether a fund is growing, bleeding or simply marking a volatile book.
It is also published as monthly archive files that need unpacking and concatenating before anything resembling a time series exists, with older periods carrying their own encoding and column quirks.
Hindcast turns it into a queryable daily series per CNPJ with flows separated from performance, which is the distinction most analysis actually cares about: a NAV that fell because the market fell is a different fact from a NAV that fell because investors left. Fund identity resolves into the same entity graph as the portfolio data, so daily flows and disclosed positions are two views of one fund rather than two datasets.

Questions
Can I separate flows from performance?
Yes, and that separation is the main reason to use the daily file rather than a NAV series. Subscriptions and redemptions are reported directly, so asset growth attributable to investors is distinguishable from growth attributable to markets.
How does this pair with portfolio data?
The same fund identity links both, so a month where flows turned negative can be read next to the positions disclosed around it — with each side carrying its own disclosure timing.
