Common questions

Is the Sony Group Corp CEO selling stock?

Yes. Robert Stringer sold 546K shares ($12.3M) since March 18, 2026, none of it under a trading plan disclosed in the filings.

Why are Sony Group Corp insiders selling?

Filings rarely give a reason, and we don't guess at one. What they show is how the sales were made: 4% of sales by value ran under 10b5-1 trading plans disclosed in the filings, 35% were to cover taxes and 61% had no disclosed plan. A trading plan schedules sales in advance.

Are any Sony Group Corp insiders buying?

No. Officers and directors reported no purchases since March 18, 2026.

Known gaps and uncertainty24 officers and directors not confirmed

Holdings and share of stake are being verified. Balances, unit counts and every share-of-stake figure for Sony Group Corp are held back until that check is finished. Sales, proceeds, plan and tax status, titles and dates come straight from individual filings and are complete.

External context: we only cite outside events when a documented connection exists. None is shown for this period.

Sources and methodology62 filings on record, 61 filed since March 18, 2026, and how we read them

All 62 Forms 3, 4 and 5 on record for Sony Group Corp (SEC CIK 313838), filed from Aug 4, 2000 to Sep 18, 2026; 61 of them were filed in the 12 months this page covers, retrieved from SEC EDGAR on Oct 16, 2026. Prices are the ones reported in each filing, often weighted averages. 4 filings were left out because Sony Group Corp filed them as an owner of another company's stock. 1 older filing exists only on paper and could not be read.

Holdings. Each holding line (a share class plus an owner, such as a trust or LLC) carries its last reported balance forward. Entities first reported during the period start at zero, so transfers between an insider's own trusts don't count as selling. Lines not reported for three years or more are listed separately and left out of totals.

Sales. A sale counts as under a 10b5-1 plan if its footnote cites one or the filing's Rule 10b5-1 box is checked, and as tax-related if its footnote cites tax obligations or sell-to-cover. Shares withheld by the company for taxes are listed separately. Sales with neither attribute are labeled "no plan disclosed".
