黄 聖博: trading record in brief

Filings by 黄 聖博 span 2 companies, the busiest being 株式会社ストライダーズ and 盟和産業株式会社. The record holds 71 filings, for trades running from 3 March 2026 to 13 October 2026.

On the open market, the record shows 67 purchases worth €819k and 4 sales worth €1.1M. The totals exclude 66 filings filed without an amount. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant.

On 28 October 2026 came the latest disclosure, an open-market purchase for €681k in 盟和産業株式会社. This summary is built from EDINET (Japan FSA) disclosures alone and does not predict where the share price will go.
