Market trades split into 17 purchases (€38.4M) and 4 sales (€145k). No amount is published for 2 filings, which the totals therefore leave out. Unlike grants, an open-market purchase is paid for by the insider, at the market price. 2026 to date brings 2 purchases and no sales.

In size, the median ticket on the buying side is €1.6M. Clusters matter here: 6 out of 17 purchases overlapped with buying by a colleague within 30 days. Purchases made close together by different insiders form what is called a cluster.

The newest entry dates from 12 May 2026: an open-market purchase of €2.5M, in Keppel DC REIT Management Pte. Ltd. Most trades are made public on the day they happen. That lag is the time during which only the insider knows about the trade. These figures are compiled from regulatory filings published by SGX. They describe what insiders did and are not a recommendation.
