RIBOMIC Inc. Stock: price and insider trades · Japan

RIBOMIC Inc. is a listed company. Its directors and officers file their transactions with EDINET (Japan FSA). Over the twelve months to 18 October 2026, the company's managers filed 9 filings, 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. Because grants and exercises are largely decided by remuneration plans, they are not counted as purchases here.

With 9 filings in twelve months, the company is more active than the median of 3 filings across the 3,419 companies we follow on the same exchange.

There has been no open-market purchase by an insider of RIBOMIC Inc. for at least a year. Typically, a trade is published a median of 7 days after it takes place. That lag is the time during which only the insider knows about the trade.
