SQM

Sociedad Química y Minera de Chile (SQM), classified in the Materials sector, has attracted a narrow level of congressional trading activity, with just two distinct members disclosing a combined three trades in public filings spanning from February 2023 through March 2025. The disclosed activity tilts toward net buying, comprising two purchases against one sale, with Thomas Carper and Sheri Biggs identified as the most active filers in this name. No bipartisan co-trading clusters are recorded for this security, and no executive-branch officials have disclosed transactions in SQM within the available public record.
