Burkhard Otto Cordes is a declared insider at 2 companies; the most frequent names are Cosan Ltd. and Cosan S.A. Between 18 May 2026 and 26 May 2026, the trades on record add up to 8 filings.
No open-market sale appears; the market trades are 8 purchases worth €1.2M. Unlike grants, an open-market purchase is paid for by the insider, at the market price.
Half of the purchases are above €110k and half below. Of 8 purchases, 3 formed part of a group of insiders buying within 30 days of each other. When several insiders buy within a few weeks of each other, analysts speak of a cluster purchase.
Most recently, on 15 September 2026, the filings show an open-market purchase worth €341k in Cosan S.A. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
