Chiang Sang Sem

All filings by Chiang Sang Sem on record concern Bonia Corporation Berhad. Over a trading history stretching from 14 July 2026 to 28 September 2026, the count stands at 22 filings.

Purchases make up the whole of the open-market record (22 purchases, €95k). Unlike grants, an open-market purchase is paid for by the insider, at the market price.

The median purchase comes to €2,648. Measured against the company's value, the median purchase equals 0.0077% of market capitalisation, across 22 purchases where it is known. No cluster: in 22 purchases, no other insider of the company bought within 30 days.

On 29 September 2026 came the latest disclosure, an open-market purchase for €4,507 in Bonia Corporation Berhad. Filings reach the Bursa Malaysia (SC) feed a median of 1 day after the trade. This delay matters because a trade only becomes useful information once it is public. Every figure here comes from the filings published by Bursa Malaysia (SC) and describes the past, not future prices; it is not investment advice.
