Dados B3

Dados B3 provides fundamentals and market statistics for the ~450 companies listed on B3 (Brazil's stock exchange), banks and insurers included, from 2010 to today, plus market indices, ETFs and BDRs.

Every figure carries the CVM account it came from, and the full methodology is public. Valuation multiples are priced at the first trading session on or after the filing became public, so there is no look-ahead.

What you can ask:

• Dividends and interest on equity per share for any listed ticker, with a yearly summary and the trailing 12-month dividend yield.
• Performance of a stock or of a B3 index over any period: price return, total return with dividends reinvested, maximum drawdown and volatility.
• A plain-language verdict on a company's latest year: does it make money, is it indebted, is it expensive against its sector and its own history.
• ETF rankings, the list of BDRs that trade on B3, and the list of listed companies and indices.
• What changed in the Brazilian market in the last 30 days, how current the data is, the methodology behind each metric, a data dictionary and a reproducible audit sample.
