郑志新 (board member) discloses dealings in 长芯博创 to SSE / SZSE (CSRC). The record holds 4 filings, for trades running from 23 December 2021 to 27 April 2023.

No open-market purchase appears, only 4 sales worth €641k. In 2023 alone, the filings show no purchases and 3 sales.

On 27 April 2023 came the latest disclosure, an open-market sale for €124k in 长芯博创. Publication is fast: at least half of the trades appear on SSE / SZSE (CSRC) on the same day. 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.
