B3 Investor Flow — who buys and sells on the exchange
Every trading day, B3 (Brazil's stock exchange) publishes how much each investor category bought and sold in stocks. The net balance (buys − sells) shows who is putting money into the market and who is pulling it out. Foreign capital tends to be the biggest driver of the Ibovespa. Official data from B3's Daily Market Bulletin — no opinion, just the numbers.
