How the engine reached this verdict
TrendMatrix's engine output for Qualys, Inc. (QLYS) is SELL_IF_HOLDING with high conviction, score 5.1/10 at $115.87. The F-path SELL output reflects an overall score of 3.6 below the 5.6 soft trigger — multiple weakening dimensions accumulated rather than a single hard-floor breach. Asymmetry R:R of -1.11 is supplementary context, not the trigger.
The dominant failed gate is momentum at 4.0 vs threshold 4.5 (with co-failures: reward-to-risk, death cross). SELL flips back toward HOLD if momentum recovers above its threshold AND a co-failing gate also clears. The strongest-cleared gate today is INSIDER:OK.
On the bull side: Strong earnings beat streak (4/4); High-quality business. On the bear side: Concentration risk — Geographic: United States (56.0%); Analyst target reached - limited upside remaining; Leverage penalty (D/E 9.2): -1.5. Active engine warnings: V8: Target reached (-16.7% upside), V9 Gate Failed: MOMENTUM:4.0<4.5, V9 Gate Failed: ASYMMETRY:-1.1=NEGATIVE.
The engine's exit framework anchors to a tactical sell band near $115.87, with structural invalidation at $107.86. The asymmetric R:R against a reversal hypothesis is 0.01 — 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).
