鄭成田

鄭成田 is a declared insider of 中揚光, with filings sourced from TWSE / TPEx (MOPS). Between 3 October 2018 and 2 July 2025, the trades on record add up to 6 filings.

The filings describe grants, exercises and other transfers rather than trades on the open market. Because grants and exercises are largely decided by remuneration plans, they are not counted as purchases here.

On 2 July 2025 came the latest disclosure, a transaction in 中揚光. The median gap between trade and publication is zero days: most filings appear on the same day. This delay matters because a trade only becomes useful information once it is public. This summary is built from TWSE / TPEx (MOPS) disclosures alone and does not predict where the share price will go.
