Factor checklist — research, not advice

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

  • Insider Pulls against a bullish reading. Selling cluster — sale value, no purchase value
  • Congress Unavailable or mixed. 4 purchase disclosures year to date, a thin reading
  • Narrative Unavailable or mixed. Stored narrative reading is in the neutral band
  • Timing Pulls against a bullish reading. Close is more than 0.5 ATR under stored support
  • Financial indicators Supports a bullish reading. Current ratio 1.59 · operating margin 15%

Suggested stop 115.70, nearest stored support minus 0.5 ATR(12.3% under the last close). Reward/risk to the next stored resistance is 1.12. Wait — that reward/risk is under 2. Research, not advice. Not an order.
