BeOne Medicines Ltd. (ONC) insiders executed a small cluster of open-market sales totaling $1.49M over eight days, led by the CEO ($1.03M) and President/COO ($389K). At a $29.8B market cap, the total represents ~0.005% of the company — a trivial economic signal that does not outweigh the fact that the CEO and COO sold near the same price on the same day, which is more likely driven by post-vesting tax planning than a coordinated bearish view. Historical call calibration on ONC shows an avg T+20 alpha of -2.26% in this segment with a 0% win rate over the last two settled reports, suggesting prior cluster reads were over-scored.
