Derived numbers (every cross-ticker aggregate with the full formula shown):

• ●Daily changes: (−4.40 −8.10 −8.04 −4.52 −4.31 −2.88 −6.26 −5.20) ÷ 8 = −43.71 ÷ 8 = −5.46% group average [T1-derived: see formula]
• ●Average excluding SMCI, 7 names: (−43.71 − (−5.20)) ÷ 7 = −38.51 ÷ 7 = −5.50% [T1-derived: see formula]
• ●Median of the 8 daily changes: sorted (−2.88, −4.31, −4.40, −4.52, −5.20, −6.26, −8.04, −8.10); middle pair (−4.52 + −5.20) ÷ 2 = −4.86% [T1-derived: see formula]
• ●Breadth: 0 of 8 up; 8 of 8 red [T1-derived: from the eight change values above]
• ●Worst − best spread: AMD −8.10% − QCOM −2.88% = 5.22 pp [T1-derived: see formula]
• ●Position in day range (price − low) ÷ (high − low):
  • ●NVDA: (212.21 − 211.26) ÷ (218.88 − 211.26) = 0.95 ÷ 7.62 = 12.5% (near lows) [T1-derived]
  • ●AMD: (507.93 − 502.60) ÷ (529.98 − 502.60) = 5.33 ÷ 27.38 = 19.5% (near lows) [T1-derived]
  • ●INTC: (85.49 − 84.65) ÷ (89.19 − 84.65) = 0.84 ÷ 4.54 = 18.5% (near lows) [T1-derived]
  • ●TSM: (412.35 − 410.22) ÷ (421.91 − 410.22) = 2.13 ÷ 11.69 = 18.2% (near lows) [T1-derived]
  • ●AVGO: (323.24 − 321.02) ÷ (330.82 − 321.02) = 2.22 ÷ 9.80 = 22.7% [T1-derived]
  • ●QCOM: (172.83 − 171.93) ÷ (178.70 − 171.93) = 0.90 ÷ 6.77 = 13.3% (near lows) [T1-derived]
  • ●MU: (856.49 − 849.25) ÷ (908.30 − 849.25) = 7.24 ÷ 59.05 = 12.3% (near lows) [T1-derived]
  • ●SMCI: (33.72 − 32.96) ÷ (34.93 − 32.96) = 0.76 ÷ 1.97 = 38.6% [T1-derived]

• ●Eight-for-eight red on Oct 22: group average −5.46%, median −4.86%, breadth 0/8 [T1-derived: see Phase 0 formulas]. Every name closed near its day low (range position 12–23% for seven of eight; SMCI highest at 38.6%) [T1-derived].
• ●Volume expansion across the board: every name except SMCI printed elevated volume on the selloff [T1-derived]. SMCI volume cooled to more normalized levels after Monday's spike [T1-derived].
• ●The AI trade unwind deepened: Big-tech earnings anxiety spilled into chip names, with AMD (−8.10%) and INTC (−8.04%) leading losses [T1: Verified]. The midday report's scenario B (profit-taking / pullback) materialized and exceeded its −0.5% to −1.5% band [T3: Model estimate — unverified, subject to change].
• ●Two-day cumulative damage: group average −2.78% from Oct 20 close, with INTC (−6.76%) and AMD (−5.01%) hardest hit; SMCI the only survivor at +3.85% [T1-derived].
• ●Pre-open setup for Oct 23: Market in PRE session. No live quote available until 09:30 EDT. Overnight sentiment will be shaped by whether any earnings surprises or macro headlines emerge before the bell [T3: Model estimate — unverified, subject to change].

• ●Confidence: Low-Medium [T3: Model estimate — unverified, subject to change]

Volume & Tape

• ●Every name except SMCI saw 144–209% of prior-day volume [T1-derived]. This is not a low-conviction drift — it is active distribution.
• ●INTC's 178% relative volume on an −8% drop suggests institutional repositioning or stop-loss cascades [T3: Model estimate — unverified, subject to change].
• ●QCOM's 209% volume on a relatively modest −2.88% decline is notable — buyers may have stepped in at lower levels [T3: Model estimate — unverified, subject to change].

Range Analysis

• ●Seven of eight names closed in the bottom quartile of their day range (position <25%) [T1-derived].
• ●SMCI at 38.6% is the exception, consistent with its two-day outperformance and Monday's short-squeeze dynamics [T3: Model estimate — unverified, subject to change].

Two-Day Context

• ●From Oct 20 close: group average −2.78%, with SMCI (+3.85%) the only green name [T1-derived].
• ●INTC (−6.76%) and AMD (−5.01%) have suffered the most damage, suggesting high-beta names are being sold first in the unwind [T3: Model estimate — unverified, subject to change].
• ●NVDA (−1.97%) and QCOM (−1.64%) show relative resilience, consistent with their status as "quality" names in the sector [T3: Model estimate — unverified, subject to change].

Scenario A: Bounce / Relief Rally

• ●Trigger: Oversold conditions after two days of selling; dip-buyers emerge at key support levels [T3: Model estimate — unverified, subject to change].
• ●Expected action: Group recovers +1.5% to +3.0%; SMCI and AMD lead given their high-beta profiles [T3: Model estimate — unverified, subject to change].
• ●Probability: 35% [T3: Model estimate — unverified, subject to change]

Scenario B: Continued Unwind / Distribution

• ●Trigger: Earnings anxiety persists; no positive macro catalyst before the bell; sector rotation out of AI continues [T3: Model estimate — unverified, subject to change].
• ●Expected action: Group drops another −1.0% to −2.5%; INTC and AMD most vulnerable [T3: Model estimate — unverified, subject to change].
• ●Probability: 45% [T3: Model estimate — unverified, subject to change]

Scenario C: Sideways / Consolidation

• ●Trigger: Mixed signals; some dip-buying but sellers still active; market awaits more earnings clarity [T3: Model estimate — unverified, subject to change].
• ●Expected action: Group trades in a ±1.0% range; volume declines from Wednesday's spike [T3: Model estimate — unverified, subject to change].
• ●Probability: 20% [T3: Model estimate — unverified, subject to change]

• ●Earnings volatility: Big-tech earnings (META, TSLA reported 10/21) can spill over into chip sentiment [T3: Model estimate — unverified, subject to change].
• ●Macro sensitivity: Treasury yields and Fed policy expectations remain key drivers for growth/tech multiples [T3: Model estimate — unverified, subject to change].
• ●Geopolitical: Taiwan Strait tensions remain a tail risk for TSM and the broader supply chain [T3: Model estimate — unverified, subject to change].
• ●Position sizing: High-beta names (AMD, SMCI) warrant smaller position sizes in volatile regimes [T3: Model estimate — unverified, subject to change].
