No actionable signal. The dollar amount is noise for a $41B company. Monitor the next 10-Q for any change in the fundamental narrative — this cluster is not predictive.
Price Chart
Executive Summary
Two ONC insiders (PAO Ball and COO Wu) sold a combined $153K in open-market transactions over a one-week window. The cluster value is ~0.0004% of the $41.1B market cap, well below any materiality threshold. The sales follow the company's H1 2026 STAR Market dual-listing update (filed 9 days earlier), but the minuscule amounts relative to market cap and the executives' typical holdings indicate routine diversification, not a bearish signal.
Key Financial Metrics
Key Facts
- Principal Accounting Officer Ball sold 132 shares ($47K) on Sep 1, 2026 at $355.86.
- President & COO Wu sold 280 shares ($106K) on Aug 25, 2026 at $380.00.
- Total cluster value of $153K represents ~0.0004% of ONC's $41.1B market cap.
- Cluster follows the Aug 26, 2026 STAR Market dual-listing disclosure (neutral, impact 2).
- Prior reports on ONC have a 60% win rate T+20 and avg alpha +3.00%.
