Isao Miyamoto

Isao Miyamoto is a declared insider at 3 companies (major shareholder); the most frequent names are 株式会社HCSホールディングス, 宮本 公 and 株式会社日比谷コンピュータシステム. Between 24 June 2021 and 16 October 2023, the trades on record add up to 5 filings.

No open-market purchase or sale appears among the filings, only grants, plan transactions and other operations. Compensation-driven entries like these are tracked, but they say little about how insiders judge the share price.

On 19 October 2023 came the latest disclosure, a transaction in 株式会社HCSホールディングス. Typically, a trade is published a median of 3 days after it takes place. That lag is the time during which only the insider knows about the trade. These figures are compiled from regulatory filings published by EDINET (Japan FSA). They describe what insiders did and are not a recommendation.
