How the engine reached this verdict
TrendMatrix's engine output for Tandem Diabetes Care, Inc. (TNDM) is SELL_IF_HOLDING with medium conviction, score 5.1/10 at $15.32. An L1 hard-floor gate blocked the positive-verdict path — Quality below minimum threshold. Co-failing gates ( MOMENTUM:2.6<4.5) reinforce the read; dimensional pillars cannot lift the engine output above the verdict floor while the L1 gate is active.
The dominant failed gate is momentum at 2.6 vs threshold 4.5. SELL flips back toward HOLD if momentum recovers above its threshold AND a co-failing gate also clears. The strongest-cleared gate today is ASYMMETRY:5.8>=1.5.
On the bear side: Concentration risk — Supplier: Unomedical A/S; Quality below floor (3.1 < 4.0). Active engine warnings: Quality below floor (3.1 < 4.0), V9 Gate Failed: MOMENTUM:2.6<4.5.
The engine's exit framework anchors to a tactical sell band near $15.32, with structural invalidation at $14.25. The asymmetric R:R against a reversal hypothesis is 5.85 — the upside scenario exists, but it requires multiple structural gates to flip; the downside scenario requires only one more disappointment. The engine's sizing output: 0.5% of portfolio at this asymmetry level (none-conviction tier).
