2026-10-30 10:00 update

• 10-30 ~10:13 ET: +3.30%, above OR30 high. Q3 (10-22) lost 144k domestic broadband customers (Comcast IR). Charter reports Nov 6, 7:00 ET (Charter).
• 2026-10-30 10:00 — open follow-through, telecom/pharma bid, software split, events blind spot

2026-10-30 17:00 update

• Close +4.27%, relVol 1.56, rangePos 0.87 → long_momentum on final data (5:04 PM local re-run). It was missing from the official 4:21 PM run because of a stale bar (run close 23.08 vs final 23.22). This is not a print day: Q3 was reported 10-22 (TRAI /api/events). The catalyst is unconfirmed. An AI-generated Quiver note cites the Q3 beat and the planned NBCU/Sky separation (Quiver, 2026-10-30). Probably telecom/defensive rotation (TMUS +6.2%).
• 2026-10-30 17:00: stale postclose run, corrected buckets

• Friday's +4.27% was not a print day (Q3 was 10-22: adj. EPS $1.07 vs $0.98, CNBC). Catalyst still unconfirmed; read as low-beta rotation (beta60 −0.34).
• Linkages (60d, asOf 10-30): cluster 9 with VZ/T/TMUS; SPOT ρ 0.52 (different cluster, but TRAI's "Internet/Media ×2" flag pairs them). See S-125. CHTR reports 11-06 BMO.
