Su Ertian: trading record in brief
Su Ertian is a declared insider of Global New Material International Holdings Ltd. (chief executive), with filings sourced from HKEX. In total, 52 filings cover trades dated from 16 July 2021 to 22 October 2026.
Both buying and selling appear: 37 purchases worth €28.4M, against 13 sales. The totals exclude 13 filings filed without an amount. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. Since January 2026: 18 purchases and 1 sale on the market.
Half of the purchases are above €392k and half below. Relative to company size, the median is 0.030% of market cap (16 purchases with a known value). None of the 36 purchases we analysed coincided with buying by another insider of the same company within 30 days. Ninety days after publication, 36 purchases show a median change of +20.5%, with the price up in 58% of them. They describe history only and say nothing certain about the share price ahead.
On 23 October 2026 came the latest disclosure, an open-market purchase for €170k in Global New Material International Holdings Ltd. The median gap between a trade and its publication by HKEX is 2 days. The shorter that gap, the sooner other investors can see what insiders have done. This summary is built from HKEX disclosures alone and does not predict where the share price will go.
