Congressional Activity

Smicroelectronics (STM)

ARIA INTELLIGENCE BRIEF

Congressional disclosure records show two members — Byron Donalds and Daniel Goldman — filing a combined three trades in this Information Technology sector security between February 24, 2023 and October 19, 2023, with the activity skewing toward selling: one purchase against two sales. No bipartisan co-trading cluster is recorded for this ticker, and the overall congressional footprint in the name is limited by count and volume. One executive-branch official has also disclosed a single transaction in the same security within the public filing record, representing an independent sequence of disclosures with no purchase-to-purchase proximity computed.

Signal Congress surfaces public disclosure data. This is not investment advice and does not imply wrongdoing.
