10 of the members we track disclosed 19 purchases of MRK between 2022-03-30 and 2026-08-19, and 23 sales. Here is what the stock did afterwards.

How these buys are tagged
Merck & Company, Inc. 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. 4 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 23 disclosed sales of MRK are not in this table.
