BEARISH30d +6.2% vs SPYSayiner (SNDK director) sells $870K stake, first trade on file101d ago
Director Necip Sayiner executed a Code-S open-market sale of 579 shares at $1503.11 on 2026-05-08, reducing holdings by 16.6% from 3,479 to 2,900 shares and generating $870K in proceeds. This is the insider's first Form 4 filing on record—no prior Code-P buys or Code-S sales exist—and occurs with zero offsetting officer or director purchases in the 60-day cluster window. The sale occurred 3.9% below the 90-day high of $1564.00 and 190.7% above the 90-day low of $517.00, in a stock with 27-analyst STRONG BUY consensus (22 buy / 5 hold / 0 sell).
Where it could go — First-time director sales with no prior trading history carry elevated noise risk; however, if this pattern holds across comparable one-time sellers, the stock historically declines in the 30–90 day window post-sale—invalidated if SNDK holds above the $1564 recent high or if subsequent insider buys emerge within 30 days.
