The Basic Materials Index (IMAT) is compiled as a weighted average of a theoretical portfolio of stocks pursuant to criteria set forth in this methodology.
The indices compiled by B3 adopt concepts and practices set forth in the Concepts and Practices Manual for B3 Indices.
The IMAT is designed to track changes in the prices of the more actively traded benchmark basic materials stocks, so as to gauge average stock performance specific to the basic materials sector.
The IMAT is a total return index (see the Concepts and Practices Manual for B3 Indices).
The IMAT is composed exclusively of shares and units representing shares of B3-listed issuers that meet the inclusion criteria set forth below.
The index universe excludes Brazilian Depositary Receipts (BDRs) and shares of issuers under judicial or extrajudicial reorganization, government- or court-ordered administration or intervention, as well as shares otherwise designated to be under exceptional trading status (see the Concepts and Practices Manual for B3 Indices).
