Factor checklist — research, not advice

A check leans with a bullish reading. A cross leans against it. A dash is unavailable or mixed.

  • Insider Unavailable or mixed. – Insider: neutral. All sales (≈ $783K) were pre-planned Rule 10b5-1 trades, excluded from the score. No open-market buys or discretionary sales. – Initiés : neutre. Toutes les ventes (≈ $783K) sont sous plan 10b5-1 préétabli, exclues du score. Aucun achat ni vente discrétionnaire.
  • Narrative Unavailable or mixed. Stored narrative reading is in the neutral band
  • Congress Supports a bullish reading. 3 purchase disclosures year to date
  • Timing Pulls against a bullish reading. Close is more than 0.5 ATR under stored support
  • Financial indicators Supports a bullish reading. Current ratio 1.33 · operating margin 34%

Suggested stop 269.26, nearest stored support minus 0.5 ATR(24.4% under the last close). Reward/risk to the next stored resistance is 0.42. Wait — that reward/risk is under 2. Research, not advice. Not an order.
