Congress trades in AstraZeneca PLC (AZN)
5 of the members we track disclosed 10 purchases of AZN between 2024-10-29 and 2026-03-31, and 5 sales. Here is what the stock did afterwards.
Every purchase is measured over the three months after the transaction date, against XLV — the ETF standing in for Healthcare & Pharma — over exactly the same dates. The second figure is the one that carries information: the first mostly reflects what the sector did. How AZN was classified.
How these buys are tagged
AstraZeneca PLC is a mega-cap, so a committee-aligned purchase here is tagged Aligned (Mega-cap) rather than Notable: owning a company this size says little about committee access. 5 are marked Cluster: A buy is marked Cluster when at least one other tracked member of Congress bought the same stock within 30 days of it, regardless of committee membership.

Prices are the closing price on the transaction date, not what was paid: filings never disclose an execution price. Blank figures mean the window has not elapsed yet. Sales are not scored — a sale closes a position rather than opening one — so the 5 disclosed sales of AZN are not in this table.
