Sumitomo Mitsui DS Asset Management Company, Limited

Filings by Sumitomo Mitsui DS Asset Management Company, Limited span 280 companies, the busiest being 三井住友DSアセットマネジメント株式会社, 株式会社メイコー and CKD株式会社. In total, 710 filings cover trades dated from 15 February 2022 to 8 October 2026.

None of the filings is a plain purchase or sale on the open market; they cover grants, option exercises and other movements. Grants and option exercises follow pay plans set in advance, so they reveal less about an insider's own view than a purchase made with personal money.

Most recently, on 15 October 2026, the filings show a transaction in 株式会社東光高岳. Filings reach the EDINET (Japan FSA) feed a median of 7 days after the trade. That lag is the time during which only the insider knows about the trade. Source: insider filings from EDINET (Japan FSA). Past trades are no guide to future returns.
