Insider selling at 0.02% of market cap is quantitatively trivial and does not signal a bearish view — even with CEO participation. Historical insider cluster reports on NTRA have underperformed at T+20 (30% win rate, -3.97% alpha vs SPY). Do not short or reduce position into this cluster. Monitor for any follow-on 10b5-1 plan adoption or larger multiday CEO selling pattern.
