Buys are marked to the latest close and treated as open. A sell tagged rt closes an earlier disclosed buy in the same name. exit shows how the stock moved after the member sold.
22 members of the U.S. House and Senate have disclosed McKesson Corporation transactions under the STOCK Act — 45 purchases and 20 sales. The full member-by-member breakdown, with dates and dollar ranges, is in the table above.
No member of Congress has disclosed a MCK purchase in the last 90 days. STOCK Act filings lag the trade by up to 45 days, so newer buys may still be pending disclosure.
Notional-weighted, lawmakers' disclosed MCK buys are up 24.7% versus the latest close of $992.87. Each trade's own return — and realized round-trips on matched sells — is in the Return column.
Yes. Under the 2012 STOCK Act, members of Congress may buy and sell individual stocks but must publicly disclose each transaction within 45 days. Bargo surfaces those filings so you can see who traded MCK and how it performed.
