马学绵

马学绵 appears in our data through filings on Grand Field Group Holdings Ltd. shares, published by HKEX. In total, 3 filings cover trades dated from 14 August 2018 to 15 November 2019.

On the open market, the record shows 1 purchase and 2 sales. No amount is published for 3 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. Since January 2019: no purchases and 2 sales on the market.

On 18 November 2019 came the latest disclosure, an open-market sale in Grand Field Group Holdings Ltd. The last purchase on record was published on 17 August 2018, which is 2,991 days ago. Typically, a trade is published a median of 3 days after it takes place. This delay matters because a trade only becomes useful information once it is public. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. Source: insider filings from HKEX. Past trades are no guide to future returns.
