Arm inc

Arm inc is a declared insider at 3 companies; the most frequent names are 株式会社セイファート, 株式会社セイファート and 株式会社セイファート. We count 30 filings; the first trade dates from 5 April 2023 and the latest from 5 October 2026.

None of the filings is a plain purchase or sale on the open market; they cover grants, option exercises and other movements. Such operations are usually part of compensation schedules, which makes them a weaker signal than an open-market trade.

The newest entry dates from 6 October 2026: a transaction, in 株式会社セイファート. Filings reach the EDINET (Japan FSA) feed a median of 3 days after the trade. This delay matters because a trade only becomes useful information once it is public. Source: insider filings from EDINET (Japan FSA). Past trades are no guide to future returns.
