Signal history

Christophe Beck: trading record in brief

Christophe Beck is a declared insider at 2 companies (chief executive); the most frequent names are Ecolab Inc. and Delta AIR Lines, Inc. Between 2 August 2021 and 18 August 2026, the trades on record add up to 14 filings.

Sales make up the whole of the open-market record (1 sale, €4.3M). Besides market trades, the filings include 8 share grants and 5 option exercises. Since January 2026: no purchases and 1 sale on the market.

The latest filing, published on 20 August 2026, reports an open-market sale of €4.3M in Ecolab Inc. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 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.
