2026-11-05 17:00 EST — stress MR candidate, not an overnight order
- Latest, generated Nov 5 4:49:57 PM EST, fresh postclose run: MR fade-long, close $203.88 (−9.16%), relVol 1.11, raw z1d −2.23, residualZ −0.25, ATR $13.81, below VWAP. Raw extremity is largely different from idiosyncratic residual extremity; this one case does not validate a filter.
- NET beat/raised FY guidance; TEAM also raised FY guidance despite slower forward growth versus its quarter and negative AH repricing. Different economic exposures, not a single sector sign. NET–ZS rho 0.76 (asOf Nov 4 60d) is not causal transmission evidence.
- Yahoo 5:04 PM EST AH bar $202.80 (−0.53% vs Nov 5 cash close) while NET +14.31% at 5:05 PM EST. Non-synchronized, possibly delayed/incomplete observations, not a Friday open forecast.
- No regular-session opportunity remains today. Stress label belongs to this postclose run, not a retrospectively known 10 AM signal. MR live-rule sample only 8 days: not validated edge. 17:00 report

- On TRAI 8:58 AM ET premarket run as mean_reversion_fade_long under regime stress (VIX 26.92, VIX9D/VIX 1.213). Software/security MR fade-long; indicatedGap +3.49%; Yahoo flipped ~+1.2% staging to -0.95% by ~10:31. NET peer context rho~0.76 — not automatic inheritance.
- LiveRules still mean R -0.052 / TARGET 0 — not validated edge (feeds S-144). Screening only.
