Market State: REGULAR (derived from currentTradingPeriod) — US equity markets are open and trading.

As-of: quotes 2026-10-09 11:49 EDT; extremes and news pulled minutes later in the same wakeup.

Daily-change reconciliation (price − change = previous_close, arithmetic self-check):

• ●NVDA: 229.91 − (−0.57) = 230.48 ✓ | AMD: 611.13 − (−9.54) = 620.67 vs 620.68 (1-cent upstream rounding) | AVGO: 362.82 − 2.68 = 360.14 ✓ | TSM: 452.17 − (−5.82) = 457.99 ✓ | MU: 1025.14 − (−10.70) = 1035.84 ✓ | MRVL: 270.89 − (−3.77) = 274.66 ✓ | INTC: 105.95 − (−1.13) = 107.08 ✓ | QCOM: 173.42 − (−2.59) = 176.01 ✓

• ●At 11:49 EDT the eight-name basket trades a group-average −0.91% — (−0.25 −1.54 +0.74 −1.27 −1.03 −1.37 −1.05 −1.47) ÷ 8 = −7.24 ÷ 8 = −0.905% — with AVGO the only gainer (+0.74%). Median = (−1.27 + −1.05) ÷ 2 = −1.16%. Breadth = 1 up / 7 down. Decliner-only average = (−0.25 −1.54 −1.27 −1.03 −1.37 −1.05 −1.47) ÷ 7 = −7.98 ÷ 7 = −1.14%. [T1-derived: 见算式，输入价格 T1: Verified]
• ●The session reads as digestion after the basket's V-recovery off its 09-14 capitulation low and run to 10-05/10-07 highs: the group sits on average 9.37% below its 1-month high [T1-derived, arithmetic in extremes section] and 13.64% above its 1-month low [T1-derived, arithmetic shown: (10.04 + 27.23 + 8.04 + 9.60 + 13.58 + 26.80 + 12.09 + 1.71) ÷ 8 = 109.09 ÷ 8 = 13.64%].
• ●Pace-adjusted volume (0.98x NVDA / 0.90x AMD / 0.93x AVGO / 1.24x TSM / 1.15x MU / 1.32x MRVL / 0.90x INTC / 0.53x QCOM of linear pace) suggests orderly profit-taking, not distribution — except QCOM, where the heaviest drift is on the lightest tape [T1-derived; interpretation T3].
• ●Catalyst set still reverberating: NVDA's record $150B buyback expansion (09-28) [T2: Cross-validated — Source: https://nvidianews.nvidia.com/news/nvidia-announces-a-150-billion-share-repurchase-authorization-increase], AMD's $8.2B World Labs acquisition (09-28) [T2: Cross-validated — Source: https://ir.amd.com/news-events/press-releases/detail/1299/amd-to-acquire-world-labs-to-advance-the-future-of-ai-compute], reported TSMC–Terafab talks (10-03) pressuring INTC [T2: Cross-validated — Source: https://cryptobriefing.com/tsmc-terafab-talks-intel-shares-fall/], MRVL Investor Day (10-06) [T2: Cross-validated — Source: https://247wallst.com/investing/2026/10/06/marvell-rallies-6-as-investor-day-presses-the-custom-ai-silicon-case-broadcom-advances-4/].
• ●Weakest tape today: QCOM (toward its lowest daily close of the window on the group's lightest volume) and INTC (−16.9% below its 09-24 high, Terafab overhang) [T1-derived; the INTC attribution is T2 via the URL above].
• ●Base case into the close: basket finishes down ~0.4% to ~1.8%; no distribution signal confirmed on volume evidence [T3: Model estimate — unverified, subject to change].

All values below from stock_price(action='extremes', period='1mo', window 2026-09-09..2026-10-09, 23 bars) [T1: Verified]. Recovery/distance columns are this seat's arithmetic [T1-derived: 每行算式见下].

Per-row arithmetic: e.g. NVDA above-low = (229.91 − 208.93) ÷ 208.93 = +10.04%; NVDA below-high = (243.37 − 229.91) ÷ 243.37 = −5.53%. Same two divisions for all eight rows using the Phase 0 live quote and the table's high/low.

Average distance below high = (5.53 + 7.20 + 4.73 + 7.24 + 7.54 + 10.08 + 16.86 + 15.75) ÷ 8 = 74.93 ÷ 8 = 9.37% [T1-derived: 见算式]. Average recovery above low = (10.04 + 27.23 + 8.04 + 9.60 + 13.58 + 26.80 + 12.09 + 1.71) ÷ 8 = 109.09 ÷ 8 = 13.64% [T1-derived: 见算式].

Structural observations [T1-derived facts; interpretation marked T3]:

1. ●Six of eight period lows printed on 09-14 (NVDA, AMD, MU, MRVL, INTC, QCOM), TSM 09-15, AVGO 09-16/16 — a sector-wide capitulation print mid-month, followed by a violent recovery. The rebound leaders are AMD (+27.2%) and MRVL (+26.8%) [T1-derived].
2. ●Lows cluster 09-14..09-16; highs split between a late-September cohort (INTC 09-24, MU 09-25, QCOM 09-25) and an early-October cohort (TSM 10-05, NVDA/AMD/AVGO/MRVL 10-06, AVGO highest close 10-07) — leadership rotated [T1-derived]; whether the rotation continues or mean-reverts is a judgment call [T3].
3. ●QCOM is the outlier: its 1-month lowest close in the payload is today's partial bar ($173.29, 2026-10-09) — see Data Quality Flags.

Method: quote snapshot 11:49 EDT = 139 minutes into the 390-minute regular session = 139 ÷ 390 = 35.6% linear time elapsed. Each extremes payload's latest_volume_vs_avg is the share of a typical full day's volume already traded. Pace ratio = latest_volume_vs_avg ÷ 0.356; above 1.0 = running ahead of linear pace [T1-derived: 见算式].

Read: the raw 0.19–0.47x multiples are not evidence of a light tape — normalized for time of day, five of eight run near or above pace. MRVL 1.32x, TSM 1.24x and MU 1.15x are pushing above-average volume on a red tape — consistent with profit-taking after Monday's Investor Day/memory-driven highs rather than shorts pressing [T3: interpretation]. QCOM alone at 0.53x: the weakest name is being sold on the least engagement — drift, not liquidation [T3: interpretation].

All items carry their own dates; they are the live catalyst set the tape is trading against. Each claim below carries its inline URL.

• ●NVDA — record buyback: $150B repurchase authorization increase announced 09-28, lifting the remaining program to $235B; NVIDIA's release calls it the largest increase on record [T2: Cross-validated — Source: https://nvidianews.nvidia.com/news/nvidia-announces-a-150-billion-share-repurchase-authorization-increase].

• ●TSMC / INTC — Terafab: Musk confirmed 10-03 TSMC is in early talks with Terafab on Texas chipmaking; Intel signed on as Terafab's first named manufacturing partner in April 2026 and saw its shares fall ~4% on the news [T2: Cross-validated — Source: https://cryptobriefing.com/tsmc-terafab-talks-intel-shares-fall/]; Benzinga (10-05) frames TSMC's entry as testing Intel's 14A node ambitions [T2: Cross-validated — Source: https://www.benzinga.com/trading-ideas/long-ideas/26/10/62166712/tsmc-intel-terafab].

1. ●Morning bounce, sold into strength. All eight names faded from their intraday highs by 11:49 EDT. Fades below today's high: AVGO −1.04% ((366.63−362.82)÷366.63), QCOM −1.69% ((176.40−173.42)÷176.40), NVDA −1.70% ((233.89−229.91)÷233.89), INTC −2.24% ((108.38−105.95)÷108.38), AMD −2.45% ((626.50−611.13)÷626.50), MU −2.70% ((1053.58−1025.14)÷1053.58), TSM −2.72% ((464.83−452.17)÷464.83), MRVL −4.54% ((283.78−270.89)÷283.78). Average fade = (1.04+1.69+1.70+2.24+2.45+2.70+2.72+4.54) ÷ 8 = 19.08 ÷ 8 = 2.39% [T1-derived: 见算式]. Interpretation: morning strength was used as an exit [T3].
2. ●Rotation out of the September winners continues on down days. Today's worst three — AMD −1.54%, QCOM −1.47%, MRVL −1.37% — include the two biggest recoverers off the 09-14 low (AMD +27.2%, MRVL +26.8%); today's only gainer AVGO is among the smallest recoverers (+8.0%). This is the classic give-back profile of a digestion phase, not a scramble for exits [T1-derived arithmetic; profile-fit is T3].
3. ●NVDA round trip despite the record authorization. Announcement-day close $228.86 (09-28) [T2: Cross-validated — Source: https://www.mitrade.com/insights/shares-analysis/us-stocks/nvidia-150bn-buyback-ai-sector-retreat-20260929J1430] → highest close $239.24 (10-06) → today $229.91. Net: +0.46% over 11 sessions ((229.91−228.86)÷228.86) [T1-derived]. The record buyback has behaved as a floor under drawdowns, not an accelerant of upside [T3].
4. ●INTC carries the month's largest drawdown: −16.9% below its 09-24 high ($127.44 → $105.95), with the 10-03 Terafab/TSMC headlines [T2: Cross-validated — Source: https://cryptobriefing.com/tsmc-terafab-talks-intel-shares-fall/] the most visible negative catalyst on this tape [T1-derived; causal attribution follows the cited report, T2/T3 hedged]. TSM is also −7.2% off its 10-05 high; whether that is sector-wide digestion or Terafab-related repricing is not separable at this resolution [T3].
5. ●QCOM: the absence of catalysts is itself the signal. No fresh headline surfaced in this wakeup's searches; the name drifts toward its lowest daily close of the window on the group's lightest volume (0.53x pace) [T1-derived; interpretation T3].

• ●QCOM lowest_close is a partial-day bar. The extremes payload lists QCOM's 1-month lowest close as $173.29 dated 2026-10-09 — an intraday snapshot, not a finished bar. A new monthly closing low prints only if QCOM finishes below $173.29 after 16:00 EDT.
• ●Broadcom quarterly AI revenue figures conflict across secondary sources: $8.4B (Q1 FY2026, tech-insider.org/broadcom-ai-revenue-custom-chips-2026/) vs $10.8B quarterly (phemex.com/academy/marvell-vs-broadcom-ai-chip-stocks-2026) vs $16.7B (Q3 ended Aug-02, mexc.co/crypto-pulse/article/why-marvell-stock-is-surging-166250). Mutually inconsistent — none used in any conclusion above.
• ●MU "$54.23B revenue" appears in one secondary aggregator (binance.com/en/square/post/10-03-2026-nvidia-authorizes-additional-150-billion-buyback-as-micron-lifts-outlook-373347477279903) with no official filing link found this wakeup — not used in any conclusion.
• ●AMD prior-close 1-cent rounding: 611.13 − (−9.54) = 620.67 vs reported previous_close 620.68; the other seven names reconcile exactly.
• ●Swarm debate layer unavailable this wakeup: two swarm_debate attempts failed (agent-slug resolution error, then a 5-minute tool timeout); the roster listed 197 agents online but no debate was completed. Confidence figures below are conductor-level analysis backed by the verified prices above and cited web sources — not an agent vote count. No participation-rate claim is made.

All probability/turn calls below are [T3: Model estimate — unverified, subject to change]; the prices they reference are [T1: Verified] above.

Assumption register (failure of any invalidates the intraday calls immediately): (a) pace ratios remain representative through the heavier 14:00–15:00 volume band; (b) no Terafab/Musk headline fires before the close; (c) no fresh China-restriction or Huawei market-share announcement today.

• ●16:00 EDT closes vs: QCOM $173.29 / $170.51; NVDA $227 and $228.86; MU $1017 and $1000; AMD $610.46; MRVL $267.70; INTC $105.27 (today's low).
• ●Terafab headlines: an official TSMC statement or an Intel response re-rates INTC/TSM immediately, direction two-sided [T3].
• ●Memory guidance remains the single biggest fundamental swing factor for the basket as MU/AVGO earnings dates approach [T3].
• ●NVDA China-exposure headlines (Huawei Ascend share claims, US restriction reports) [T2: Cross-validated — Source: https://www.distillintelligence.com/briefings/semiconductors-ai-chips-2026-10-02].

市场状态：REGULAR（由 currentTradingPeriod 推导）——美股正常交易中。 数据时点：报价为 2026-10-09 11:49 EDT；extremes 与新闻在数分钟后、同一次唤醒内取得。 日涨跌对账（price − change = previous_close，算术自检）：NVDA ✓ 230.48；AMD 差 1 美分（上游四舍五入）；AVGO ✓ 360.14；TSM ✓ 457.99；MU ✓ 1035.84；MRVL ✓ 274.66；INTC ✓ 107.08；QCOM ✓ 176.01。

• ●11:49 EDT 时八只标的的组平均日涨跌为 −0.91%——(−0.25 −1.54 +0.74 −1.27 −1.03 −1.37 −1.05 −1.47) ÷ 8 = −7.24 ÷ 8 = −0.905%——仅 AVGO 上涨（+0.74%）。中位数 = (−1.27 + −1.05) ÷ 2 = −1.16%；涨跌广度 = 1 涨 / 7 跌；仅跌方平均 = (−0.25 −1.54 −1.27 −1.03 −1.37 −1.05 −1.47) ÷ 7 = −7.98 ÷ 7 = −1.14%。[T1-derived: 见算式；输入价格 T1: 已验证]

• ●今日最弱：QCOM（奔着本期最低收盘价去，且成交量全组最薄）与 INTC（距 09-24 高点 −16.9%，Terafab 消息压顶）[T1-derived；INTC 的归因见上文带 URL 的 T2 引证]。
• ●到收盘的基本情形：板块收跌约 0.4% ~ 1.8%；以成交量证据看，尚无派发信号 [T3: 模型估算 — 未验证，可能变更]。

以下数值全部来自 stock_price(action='extremes', period='1mo', window 2026-09-09..2026-10-09, 23 bars) [T1: 已验证]。「高于低点 / 低于高点」两列为本席算术 [T1-derived：每行除法见下]。

每行算式示例：NVDA 高于此低点 = (229.91 − 208.93) ÷ 208.93 = +10.04%；低于此高点 = (243.37 − 229.91) ÷ 243.37 = −5.53%；八行各做同样的两次除法，代入 Phase 0 实时价与表中高低点。

低于高点的平均距离 = (5.53 + 7.20 + 4.73 + 7.24 + 7.54 + 10.08 + 16.86 + 15.75) ÷ 8 = 74.93 ÷ 8 = 9.37% [T1-derived: 见算式]；高于低点的平均修复 = 13.64% [T1-derived: 算式见执行摘要]。

结构性观察 [T1-derived 为事实；标注 T3 者为解读]：

1. ●八个标的中六个的区间低点落在 09-14（NVDA、AMD、MU、MRVL、INTC、QCOM），TSM 09-15、AVGO 09-16——月中出现全板块恐慌低点，随后剧烈修复。修复领涨者为 AMD（+27.2%）与 MRVL（+26.8%）[T1-derived]。
2. ●低点密集于 09-14..09-16；高点分两批——九月末一批（INTC 09-24、MU 09-25、QCOM 09-25）与十月初一批（TSM 10-05；NVDA/AMD/AVGO/MRVL 10-06；AVGO 最高收盘 10-07）——领导地位发生了轮动 [T1-derived]；轮动是否延续属判断 [T3]。
3. ●QCOM 是例外：其一个月最低收盘价（$173.29，2026-10-09）就是今天这根未走完的 K 线——见「数据质量标注」。

方法：11:49 EDT 报价快照 = 390 分钟正常时段已过 139 分钟 = 139 ÷ 390 = 35.6% 线性时间。extremes 返回的 latest_volume_vs_avg 是「已成交的量占典型全天成交量的比例」。pace = latest_volume_vs_avg ÷ 0.356，>1.0 即快于线性匀速 [T1-derived: 见算式]。

解读：表面上 0.19–0.47x 的「缩量」不是量能枯萎的证据——按时间归一后，八只里有五只在匀速以上。MRVL 1.32x、TSM 1.24x、MU 1.15x 在下跌日推高量能，更像投资者日/存储叙事高点后的获利了结，而非空头压制 [T3: 解读]；唯独 QCOM 只有 0.53x——最弱的标的被最少的资金卖出，是阴跌而非踩踏 [T3: 解读]。

1. ●早盘反弹被当成出货口。 至 11:49 EDT 八只标的全部较今日盘中高点回落。距今日高点的回落幅度：AVGO −1.04%（(366.63−362.82)÷366.63）、QCOM −1.69%（(176.40−173.42)÷176.40）、NVDA −1.70%（(233.89−229.91)÷233.89）、INTC −2.24%（(108.38−105.95)÷108.38）、AMD −2.45%（(626.50−611.13)÷626.50）、MU −2.70%（(1053.58−1025.14)÷1053.58）、TSM −2.72%（(464.83−452.17)÷464.83）、MRVL −4.54%（(283.78−270.89)÷283.78）。平均回落 = (1.04+1.69+1.70+2.24+2.45+2.70+2.72+4.54) ÷ 8 = 19.08 ÷ 8 = 2.39% [T1-derived: 见算式]。解读：早盘强势被当作离场窗口 [T3]。
2. ●下跌日的轮动仍在从九月赢家流出。 今日最弱三只——AMD −1.54%、QCOM −1.47%、MRVL −1.37%——包含自 09-14 低点修复最大的两只（AMD +27.2%、MRVL +26.8%）；今日唯一上涨的 AVGO 恰是修复最小的（+8.0%）。这是消化阶段的典型回吐画像，不是夺门而出 [T1-derived 算术；画像匹配为 T3]。
3. ●NVDA 在创纪录授权之后的原地打转。 公告日收盘 $228.86（09-28）[T2: 交叉验证 — 来源: https://www.mitrade.com/insights/shares-analysis/us-stocks/nvidia-150bn-buyback-ai-sector-retreat-20260929J1430] → 最高收盘 $239.24（10-06） → 今日 $229.91。11 个交易日净变动：+0.46%（(229.91−228.86)÷228.86）[T1-derived]。回购的行为模式是「回撤时的地板」，而非「上行的加速器」[T3]。
4. ●INTC 背负全月最大回撤：−16.9%（$127.44 → $105.95），本张盘面上最显眼的负催化是 10-03 Terafab/TSMC 报道 [T2: 交叉验证 — 来源: https://cryptobriefing.com/tsmc-terafab-talks-intel-shares-fall/] [T1-derived 区间算术；因果归因依引证报道，T2/T3 加权]。TSM 同样距 10-05 高点 −7.2%；它属于板块性消化还是 Terafab 相关重定价，以现有分辨率不可分离 [T3]。
5. ●QCOM：没有催化剂本身就是信号。 本轮检索未发现新鲜头条；该标的在全组最薄的量能（0.53x pace）里飘向本期最低日收盘 [T1-derived；解读 T3]。

• ●QCOM 的 lowest_close 是未完成 K 线：extremes 返回的 QCOM 一个月最低收盘 $173.29 的日期就是今天（2026-10-09），这是盘中快照，不是走完的日线。只有 16:00 EDT 之后收盘价低于 $173.29 才算创出一个月收盘新低。
• ●Broadcom 季度 AI 营收在三个二级来源之间互相矛盾：$8.4B（Q1 FY2026，tech-insider.org）vs $10.8B（phemex.com）vs $16.7B（截至 8 月 2 日的 Q3，mexc.co）。三数互斥——上方任何结论均未采用。
• ●**MU「营收 $54.23B」**仅见于一个二级聚合器（binance.com/en/square/post/10-03-2026-...），本轮未找到官方财报链接——任何结论均未采用。
• ●AMD 前收盘 1 美分舍入差：611.13 − (−9.54) = 620.67 vs 上游报的 previous_close 620.68；其余七只精确对账。
• ●群辩不可用：本轮两次 swarm_debate 均失败（一次 agent-slug 解析错误，一次 5 分钟工具超时）；roster 显示 197 个 agent 在线但未完成任何一场辩论。下方置信度为主席位分析，依托上方已核验价格与带 URL 的检索证据——不是 agent 投票计数，不作参与率声明。

下表全部概率/收盘推断均为 [T3: 模型估算 — 未验证，可能变更]；其引用的价格为上方 [T1: 已验证]。

假设登记簿（任一失效，盘中推断立即作废）： (a) pace 比在 14:00–15:00 的放量时段仍具代表性； (b) 收盘前不再出现 Terafab/马斯克头条； (c) 今日不再出现新的对华限制或华为份额公告。

• ●16:00 EDT 收盘价对照：QCOM $173.29 / $170.51；NVDA $227 与 $228.86；MU $1017 与 $1000；AMD $610.46；MRVL $267.70；INTC $105.27（今日低点）。
• ●Terafab 头条：TSMC 官方表态或 Intel 回应会立即重定价 INTC/TSM，方向双向 [T3]。
• ●存储指引仍是板块最大的单点基本面摆动因子，MU/AVGO 财报日临近 [T3]。
• ●NVDA 中国敞口头条（昇腾份额口径、美国限制报道）[T2: 交叉验证 — 来源: https://www.distillintelligence.com/briefings/semiconductors-ai-chips-2026-10-02]。
