Chen Fei: trading record in brief
Chen Fei, listed as chief executive, has filed trades across 2 companies (mainly through SEC (Form 4)), most often in Liqtech International Inc and YSB Inc. In total, 10 filings cover trades dated from 12 September 2022 to 24 March 2026.
No open-market sale appears; the market trades are 2 purchases worth €66k. No amount is published for 1 filing, which the totals therefore leave out. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Other entries cover 8 share grants. So far in 2026, the count stands at 1 purchase and no sales.
The record was last updated on 25 March 2026 with an open-market purchase in YSB Inc. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 5 days. US insiders must file a Form 4 within two business days of a trade. Source: insider filings from SEC (Form 4). Past trades are no guide to future returns.
