Teo Cher Koon: trading record in brief
Teo Cher Koon has filed trades across 2 companies (mainly through SGX), most often in ISDN Holdings Limited and ISDN Holdings Ltd. The record holds 25 filings, for trades running from 12 January 2017 to 25 August 2026.
Market trades split into 19 purchases (€1.8M) and 1 sale. The totals do not cover 15 filings with an undisclosed amount. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. In 2026 alone, the filings show 2 purchases and no sales.
Half of the purchases are above €347k and half below. The 5 purchases reviewed show no overlap with other insiders buying the same stock within a month.
The latest filing, published on 28 August 2026, reports an open-market purchase in ISDN Holdings Ltd. Filings reach the SGX feed a median of 3 days after the trade. That lag is the time during which only the insider knows about the trade. This summary is built from SGX disclosures alone and does not predict where the share price will go.
