ISB Corporation: what insiders have been doing
This page follows insider dealings at ISB Corporation as filed with EDINET (Japan FSA). Between 18 October 2025 and 18 October 2026, 1 insider published 7 filings.
Not one of the filings records a straightforward purchase or sale on the market. Compensation-driven entries like these are tracked, but they say little about how insiders judge the share price.
There has been no open-market purchase by an insider of ISB Corporation for at least a year. The median gap between a trade and its publication by EDINET (Japan FSA) is 7 days. That lag is the time during which only the insider knows about the trade.
For context, the typical company on the same exchange (median of 3,419 companies) published 3 filings over the same period, against 7 filings here.
These figures are compiled from regulatory filings published by EDINET (Japan FSA). They describe what insiders did and are not a recommendation.
