Wong Teek Son

Wong Teek Son is a declared insider of Riverstone Holdings Limited, with filings sourced from SGX. Over a trading history stretching from 19 March 2020 to 22 May 2025, the count stands at 53 filings.

The open-market record is one-sided, with 52 purchases worth €4.9M and not one sale. No amount is published for 1 filing, which the totals therefore leave out. Unlike grants, an open-market purchase is paid for by the insider, at the market price. Since January 2025: 2 purchases and no sales on the market.

The median purchase comes to €80k. Of 51 purchases, 31 formed part of a group of insiders buying within 30 days of each other. Purchases made close together by different insiders form what is called a cluster. Looking at 50 purchases old enough to measure, the stock rose over the following 90 days in 72% of cases; the median change was +30.1%. This is a record of the past, not a forecast.

Most recently, on 22 May 2025, the filings show an open-market purchase worth €245k in Riverstone Holdings Limited. Half of the filings or more reach the SGX feed on the day of the trade. The shorter that gap, the sooner other investors can see what insiders have done. Every figure here comes from the filings published by SGX and describes the past, not future prices; it is not investment advice.
