How the engine reached this verdict
TrendMatrix's engine output for SI-BONE, Inc. (SIBN) is SELL_IF_HOLDING with medium conviction, score 5.4/10 at $17.15. An L1 hard-floor gate blocked the positive-verdict path — Quality below minimum threshold; dimensional pillars cannot lift the engine output above the verdict floor while the L1 gate is active.
The engine's exit framework anchors to a tactical sell band near $17.15, with structural invalidation at $15.97. The asymmetric R:R against a reversal hypothesis is 1.71 — 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).
On the bear side: Quality below floor (3.4 < 4.0). Active engine warnings: Quality below floor (3.4 < 4.0).
SELL output reflects multiple gate failures; recovery requires a confluence of those gates re-clearing, not a single dimension move.
