How the engine reached this verdict
TrendMatrix's engine output for Tortoise Energy Infrastructure (TYG) is HOLD_IF_HOLDING with medium conviction, score 4.5/10 at $43.26. An L1 hard-floor gate blocked the positive-verdict path — Market cap $0.93B below $1B minimum. Not in investable universe; dimensional pillars cannot lift the engine output above the verdict floor while the L1 gate is active.
On the bear side: Market cap $0.93B below $1B minimum. Active engine warnings: Market cap $0.93B below $1B minimum.
The engine is not issuing fresh-money entry targets at the current verdict. The technical entry zone is around — with a technical stop near $42.08 for existing positions. Asymmetric R:R is 0.48, 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).
Tortoise Energy Infrastructure (TYG) sits at overall score 4.5/10 with no actively-failing gates (strongest-cleared: MOMENTUM:6.4>=5.5). HOLD flips toward BUY_WAIT when a positive-conviction path (C-quality or D-momentum) triggers; toward SELL when any of the currently-passing gates drop below threshold or three+ dimensions fall below 4 simultaneously.
