郑涛: trading record in brief

郑涛 is a declared insider at 4 companies (senior executive); the most frequent names are 恒玄科技, 英联股份 and 兆易创新. The record holds 8 filings, for trades running from 24 May 2021 to 8 January 2026.

The open-market record consists of 8 sales worth €1.1M, with no purchase. Since January 2026: no purchases and 1 sale on the market.

Most recently, on 8 January 2026, the filings show an open-market sale worth €447k in 天奈科技. Publication is fast: at least half of the trades appear on SSE / SZSE (CSRC) on the same day. Until a filing is published, the market cannot know about the trade. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. Every figure here comes from the filings published by SSE / SZSE (CSRC) and describes the past, not future prices; it is not investment advice.
