Chiome Bioscience Inc.: what insiders have been doing
Chiome Bioscience Inc. is a listed company. Filings by its managers are published through EDINET (Japan FSA). Over the twelve months to 18 October 2026, 14 filings were filed, from 1 insider.
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.
Across the 3,427 companies tracked on its exchange, the median is 3 filings; at 14 filings, this issuer sits above that mark.
Insider buying of Chiome Bioscience Inc. has been absent for the past year. Typically, a trade is published a median of 7 days after it takes place. Until a filing is published, the market cannot know about the trade.
Every figure here comes from the filings published by EDINET (Japan FSA) and describes the past, not future prices; it is not investment advice.
