Pillar detail, thesis support and invalidation
Regime clarity
What strengthens the thesis
- price above 200DMA
- 200DMA rising
- 50DMA rising
- partial HH/HL structure
- efficiency ratio 0.28
- OBV 50d slope +0.166 avg-daily-volumes/bar
- price/volume history is NOT one continuous security — a single 52% session gap. A conversion, large secondary or stock merger changes the share count, so the 200DMA averages two capital structures and OBV sums two different securities. Read this pillar with suspicion.
- no OBV divergence at highs
- OBV flat-to-rising through last pullback
- last pullback 11.0% deep
- no wide downside expansion bars (30d)
- ATR expanding vs 20d mean
- cluster: 3 distinct insiders buying (3 CEO, 3 Director)
- net purchase ratio +1.00 (3 buying vs 0 selling)
- NO CFO purchase in the window — the CFO-specific terms score zero
- other insiders bought $7,671,338 (3 CEO, 3 Director) — counted through cluster breadth and net buying only
- no CFO buy to date — recency not scored
- closest sector ETF: XLV
- XLV above rising 200DMA (sector-led)
- XLV vs SPY 6m: -0.0 pts
- stock vs XLV RS (3m/6m avg): +39.6 pts
- A confirmed higher high above 34.05 on expanding OBV.
- Pullbacks that hold the rising 50DMA with flat-to-rising OBV.
- XLV extending its own trend while the stock holds relative strength.
- Continued base-building above the reclaimed 200DMA without volatility expansion.
- Loss of the rising 50DMA (28.64) with expanding volatility — reduce.
- Breakdown below the prior structural base (27.81) — exit, no averaging down.
- OBV divergence during a price acceleration — reduce.
- Sector ETF losing its own 200DMA — remove capital regardless of stock behaviour.
- CFO: —
- 0 CFO purchase(s), $0 total; last filed 2026-05-18 21:12:28
