James C. Klauer: trading record in brief
All filings by James C. Klauer on record concern Costco Wholesale CORP /new, in the capacity of senior executive. Between 14 June 2021 and 10 September 2026, the trades on record add up to 28 filings.
Every open-market trade on record is a sale: 5 sales worth €8.2M. Outside the open market, there are 22 share grants. Since January 2026: no purchases and 1 sale on the market.
The newest entry dates from 14 September 2026: a share grant, in Costco Wholesale CORP /new. The median gap between a trade and its publication by SEC (Form 4) is 3 days. For comparison, the SEC allows two business days to file a Form 4. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
