Tsutomu Kubo

Tsutomu Kubo has filed trades across 2 companies (mainly through EDINET (Japan FSA)), most often in 株式会社ラキール and 久保 努. The record holds 4 filings, for trades running from 16 July 2021 to 19 May 2025.

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.

The latest filing, published on 23 May 2025, reports a transaction in 株式会社ラキール. Between a trade and the moment it shows up on EDINET (Japan FSA), the median delay is 6 days. The shorter that gap, the sooner other investors can see what insiders have done. Source: insider filings from EDINET (Japan FSA). Past trades are no guide to future returns.
