How to read this

The weight is each stock's share of the theoretical portfolio, exactly as B3 discloses it — never recomputed by us. Stocks without their own Lume page still appear (the composition is a fact), just without a link. The portfolio is rebalanced every four months, which is why the effective date is part of the data.
