Robert Adrian Stringer eliminated his direct Sony Group Corp stake on August 5, 2026. The executive sold 545,547 $SONY shares across two open-market transactions that together fetched $12,269,352, or $22.49 per share. The sales, disclosed a day later in a single Form 4 filing, left his direct holdings at zero. They also marked the largest single-day insider disposition at Sony that year.
Stringer’s role on the filing was listed as 'See Remarks.' In the first trade, he sold 445,000 shares for $10,008,050, retaining 100,547 shares. The second trade moved those remaining shares for $2,261,302.
The August 5 sale extended a wave of insider selling that began in May 2026. Since then, six Sony insiders have sold roughly $28.3 million across nine open-market transactions. No insider has bought shares on the open market in 2026.
Director Kenichiro Yoshida unloaded 400,000 shares on May 18 for $9,044,000. CEO Hiroki Totoki parted with 225,000 shares on July 3, grossing $4,729,500. Chief Digital Officer Tsuyoshi Kodera made two cuts: 17,500 shares on May 18 and 17,100 shares on August 4, together worth $784,187. Ravi Ahuja, also classified as 'See Remarks,' sold shares on July 6 and August 4 for a combined $1,130,114. Jonathan Jose Platt, another 'See Remarks' insider, sold 16,512 shares on July 6 for $348,073.
$SONY shares closed at $22.44 on August 5, the day of Stringer’s trades, within a session range of $22.40 to $22.74. Earlier that week, the stock had ended at $23.26 on July 31 and $22.77 on July 30.
Congressional trading in $SONY was far more modest. The most recent congressional transaction was a purchase by Representative Ro Khanna, a California Democrat, in February 2026. The trade’s midpoint value was estimated at $15,001, based on STOCK Act disclosure brackets. Representative Lisa Mcclain, a Michigan Republican, executed several $SONY trades in the second half of 2025, each falling into the $1,001 range. Representative Bruce Westerman of Arkansas and Representative Susie Lee of Nevada also traded the stock in early-to-mid 2025, each at the $1,001 bracket. Congressional figures are midpoint estimates of disclosed ranges, not exact amounts.
