Joseph A. Berquist

Joseph A. Berquist (chief executive) discloses dealings in Quaker Chemical Corp to SEC (Form 4). We count 15 filings; the first trade dates from 10 August 2021 and the latest from 15 March 2026.

On the open market, the record shows 1 purchase worth €44k and 2 sales worth €426k. Taken together, the sales exceed the purchases by €381k. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. The rest of the record consists of 9 share grants and 3 option exercises.

The newest entry dates from 17 March 2026: a share grant, in Quaker Chemical Corp. The last purchase on record was published on 13 May 2025, which is 523 days ago. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. Section 16 rules allow two business days to file each Form 4. Selling is not necessarily a view on the stock: liquidity needs and diversification are common motives. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
