Ma Ning

Ma Ning has filed trades across 2 companies (mainly through SEC (Form 4)), most often in Chenghe Acquisition Co. and IMPACT Therapeutics, Inc - B - H Shares. The record holds 4 filings, for trades running from 15 February 2024 to 10 June 2026.

None of the filings is a plain purchase or sale on the open market; they cover grants, option exercises and other movements. Such operations are usually part of compensation schedules, which makes them a weaker signal than an open-market trade.

The newest entry dates from 18 June 2026: a transaction, in IMPACT Therapeutics, Inc - B - H Shares. Typically, a trade is published a median of 11 days after it takes place. Section 16 rules allow two business days to file each Form 4. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
