Tamron Co.,Ltd.: what insiders have been doing
Tamron Co.,Ltd., classified in the Retail sector, is a listed company. Its insiders report their share dealings to EDINET (Japan FSA). Over the twelve months to 26 October 2026, 7 filings were filed, from 1 insider.
Every open-market trade in the period is a purchase: 1 purchase, from 1 insider, and not a single sale. No amount is published for 1 filing, which the totals therefore leave out. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. The buyers include 1 major shareholder.
Compared with its exchange (3,205 companies, median 3 filings), a count of 7 filings is above the norm. Since 2021, the database holds 1 purchase and no sales by insiders of the company.
The last insider purchase was made public on 8 October 2026, 33 days ago. The median gap between a trade and its publication by EDINET (Japan FSA) is 7 days. That lag is the time during which only the insider knows about the trade.
