Yan Ming

Yan Ming, listed as senior executive, has filed trades across 2 companies (mainly through SEC (Form 4)), most often in Cytek Biosciences, Inc. and JF SmartInvest Holdings Ltd. We count 58 filings; the first trade dates from 10 February 2022 and the latest from 16 September 2026.

On the open market, the record shows 1 purchase and 25 sales worth €119.7M. No amount is published for 2 filings, which the totals therefore leave out. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. Outside the open market, there are 4 share grants and 24 option exercises. So far in 2026, the count stands at no purchases and 1 sale.

The latest filing, published on 18 September 2026, reports an open-market sale of €107.1M in JF SmartInvest Holdings Ltd. The last purchase on record was published on 21 July 2025, which is 457 days ago. Typically, a trade is published a median of 2 days after it takes place. US insiders must file a Form 4 within two business days of a trade. Sales are harder to read than purchases, since they often meet personal needs such as tax or diversification. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
