How the engine reached this verdict
TrendMatrix's engine output for TransMedics Group, Inc. (TMDX) is HOLD_IF_HOLDING with medium conviction, score 5.4/10 at $68.85. The F-path SELL output reflects an overall score of 4.4 below the 5.4 soft trigger — multiple weakening dimensions accumulated rather than a single hard-floor breach. Asymmetry R:R of 3.66 is supplementary context, not the trigger.
HOLD flips toward BUY_WAIT if momentum at 1.6 vs threshold 4.5 clears AND a co-confirming gate triggers. HOLD flips toward SELL if any of the currently-passing gates drop below threshold OR three or more dimensions fall below 4 simultaneously.
The engine is not issuing fresh-money entry targets at the current verdict. The technical entry zone is around — with a technical stop near $64.04 for existing positions. Asymmetric R:R is 3.66, below the threshold (≥2.0) at which the engine would actively flag fresh capital. The engine's sizing output: 0.5% of portfolio at this asymmetry level (none-conviction tier).
On the bull side: Strong earnings beat streak (3/4); Positive news sentiment (+0.67); Wide economic moat. On the bear side: Concentration risk — Supplier: third-party sterilization vendors; Leverage penalty (D/E 1.7): -1.0; Earnings estimates trending DOWN. Active engine warnings: L3:NEWS_MOD=+1: SELL_IF_HOLDING → HOLD_IF_HOLDING, V9 Gate Failed: MOMENTUM:1.6<4.5, V9 Gate Failed: DEATH_CROSS:HARD_BLOCK.
