光友股份有限公司

光友股份有限公司 discloses dealings in 光菱 to TWSE / TPEx (MOPS). We count 4 filings; the first trade dates from 18 December 2020 and the latest from 4 May 2021.

None of the filings is a plain purchase or sale on the open market; they cover grants, option exercises and other movements. Because grants and exercises are largely decided by remuneration plans, they are not counted as purchases here.

Most recently, on 4 May 2021, the filings show a transaction in 光菱. 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. These figures are compiled from regulatory filings published by TWSE / TPEx (MOPS). They describe what insiders did and are not a recommendation.
