Event window: U.S. regular close and after-hours earnings through 17:00 ET
Status: Closing prices verified; Qualcomm and Arm reactions are extended-hours prices

What changed. The U.S. election relief rally did not repair the semiconductor tape. The S&P 500 gained 1.6%, the Nasdaq Composite 1.4% and the Dow 3.0%, but the Philadelphia Semiconductor Index fell 3.1% to a six-month low. Microsoft rose 6.7%, Amazon 6.1%, Alphabet 3.2% and Meta 1.4%, while Hut 8 fell 23%, IREN 11%, Core Scientific 10% and Applied Digital 6.7%. AMD retained a 1% gain.

After-hours evidence. Qualcomm reported fiscal-Q4 GAAP revenue of \$10.32 billion; handset revenue fell 26% year over year while automotive revenue rose 89%. It guided fiscal-Q1 revenue to \$10.4–11.2 billion and non-GAAP EPS to \$2.15–2.35, but warned that broad semiconductor input-cost increases will not be fully offset in QCT margins until the second half of fiscal 2027. Shares fell about 4.9% after hours. Arm reported record quarterly revenue of \$1.44 billion, up 27%, but royalty revenue of \$670 million missed the \$720.8 million analyst estimate; shares fell about 2% in extended trading.

Tokyo transmission. CME Nikkei futures were 63,035 at 05:17 JST, 846 points above the Nikkei cash close of 62,188.63. At 05:07 JST, the U.S. 10-year yield was 4.888%, down 7.4 basis points, and WTI was \$88.59, down 7.81%. Those moves support the broader equity tape, but the U.S. close argues against treating the index gap-up as a confirmed semiconductor recovery. The highest-value test is whether Advantest, Tokyo Electron, Kioxia, Disco, Fujikura and Furukawa Electric can hold their opening ranges and VWAP while TOPIX and Prime Market breadth improve.

Counterevidence. The bearish semiconductor reading weakens if Tokyo chip and optical-infrastructure names outperform the index after the opening gap and breadth turns positive. It strengthens if the Nikkei rises mainly through non-chip large caps while Kioxia and equipment names fade below VWAP. The election result increases the probability of scrutiny and local permitting delays; it does not itself enact a federal ban on data-centre construction.

The November 4 closing update completes the opening observation. The supplied daily heatmap shows Microsoft +6.68%, Amazon +6.12% and Apple +5.31%, against NVIDIA −3.17%, Broadcom −2.00% and Micron −7.00%. AMD retained a +1.01% gain. Compared with the earlier daily snapshot, the chip leaders' divergence persisted.

NVIDIA's opening rebound did not hold through the session: later recoveries faded and the chart weakened into the close. The \$201.24 shown at the right edge belongs to 16:31 EST extended trading, not the official regular-session close. The displayed VWAP of \$202.68 is likewise a capture-time reading.

My next Tokyo test is whether semiconductor and optical-infrastructure names sustain their opening strength with broader participation. Strong U.S. indices alone do not establish that repair. Screenshots are observational evidence with differing capture times and unverified feed conditions.

The newly supplied daily-change heatmap shows Apple +6.57%, Microsoft +6.15%, Amazon +6.91% and Alphabet +4.56%, versus NVIDIA −1.20%, Broadcom −1.18% and Micron −4.25%. AMD was positive at +1.42%.

This revises the broad reading: weakness was not uniform across large technology companies, and semiconductor performance was mixed. The earlier negative figures for all four chip names described one-hour change, not daily returns. Different measurement windows can coexist; screenshot timestamps and updates are not fully synchronized. The daily map is now the primary market overview, with the earlier hourly map retained below as supplementary evidence.

At 10:31:57 EST on November 4, NVIDIA's displayed price was \$204.28, below the displayed VWAP of \$204.47. The five-minute chart shows an opening decline toward \$201, a sharp rebound above \$206 and a subsequent pullback. Those high and low zones are approximate visual readings, not verified trade extremes.

The accompanying S&P 500 heatmap uses one-hour change, not daily change: NVDA −0.14%, AMD −0.41%, Micron −0.44% and Broadcom −0.06%. The setting should not be treated as an exact opening-price return. Its narrow colour scale also makes small moves look pronounced.

The earlier premarket recovery has not yet translated into a sustained, broad semiconductor advance in these observations. Data-feed conditions and VWAP session settings remain unverified. This is an observation around the first hour, not a closing assessment or a causal claim about election news.

Event window: Tokyo close and U.S. premarket through 04:52 ET
Status: Election control projected; U.S. regular trading had not opened

What changed. Democrats won control of both the House and Senate, replacing the midday uncertainty with a projected divided-government outcome from January. President Donald Trump accepted the result. Tokyo initially treated the result as a shock to AI and data-centre spending: the Nikkei fell to 60,030.10 at 13:37 JST. It then recovered 2,158.53 points from that low to close at 62,188.63, down 893.23 points or 1.42%. TOPIX closed at 3,895.38, down 0.89%.

The recovery was real but narrow. Prime Market breadth remained weak at 423 advancers, 1,081 decliners and 42 unchanged. Advantest and Tokyo Electron removed 258.90 and 172.93 Nikkei points respectively—about 48% of the net index decline. Only eight of 33 sectors rose. The close therefore confirms a semiconductor and AI positioning shock, not a complete market repair.

The next overseas signal partially contradicted Tokyo's close. Nasdaq-100 futures had fallen as much as 2.4% and S&P 500 futures 1.4%, but by 04:22 ET they had reversed to +0.16% and +0.35%; Dow futures were +0.84%. AMD rose 7.3% in premarket after forecasting faster 2027 growth. Nvidia, Micron and Broadcom were also modestly higher in the earlier Reuters snapshot. The U.S. 10-year yield was around 4.92% and USD/JPY around 158.12.

Interpretation. Tokyo's violent decline reflected a genuine repricing of crowded Japanese AI proxies, but the late Tokyo rebound and U.S. futures reversal weaken the hypothesis that the election result alone starts a persistent global semiconductor liquidation. Democratic control can increase congressional oversight and local hurdles for data centres, especially through governorships and water or power permitting. Federal legislation still faces Trump's veto, so regulation is not an automatic outcome.

Next-session test. A constructive Tokyo open requires Advantest, Tokyo Electron, Kioxia and the cable names to reclaim opening ranges and VWAP while Prime Market breadth turns positive. A gap-up confined to index heavyweights would be only a technical rebound. The bearish case strengthens if U.S. regular trading rejects the futures recovery and data-centre, neocloud and semiconductor shares close below their premarket levels.

Publication time: 4 Nov 2026, 12:25 JST
Event window: U.S. election-night projections through 03:05 UTC / Tokyo morning session
Status: Projected state results; control of Congress remained unconfirmed

What changed. The 09:40 Tokyo note treated the semiconductor decline primarily as a valuation, positioning and liquidity reset. The next verified development added a political catalyst. Media projections showed Democrat Roy Cooper flipping North Carolina's Republican-held Senate seat and Democrat Jon Ossoff retaining Georgia. Reuters subsequently reported Democrat Annie Andrews winning South Carolina's Republican-held Senate seat in a major upset. Democrats need a net gain of four seats for Senate control; the final balance remained uncertain at the time of this update.

Market transmission. Reuters reported S&P 500 futures down 0.8%, Nasdaq futures down 1.8%, the U.S. 10-year Treasury yield six basis points lower at 4.906%, and the dollar index down 0.32%. Japan's Nikkei fell 3% after reopening from a holiday, while South Korea's KOSPI lost 1.6%. Strong AMD earnings therefore failed twice: first to protect Tokyo's crowded semiconductor trade, then to offset an election-driven repricing of U.S. fiscal stimulus and potential scrutiny of AI and Big Tech.

Inference, not settled policy. The market interpretation is that a stronger Democratic result could restrain additional fiscal stimulus and increase oversight of AI and Big Tech. No new law or confirmed congressional majority existed at publication time. Lower Treasury yields could eventually relieve discount-rate pressure, so the initial technology selloff need not persist.

Tokyo implications. The immediate pressure remains concentrated in high-beta semiconductor, AI-infrastructure and index-heavy names. A softer dollar and firmer yen also dilute the weak-yen support for exporters. Banks may lose some support from lower global yields, while defensives and domestically oriented names can retain relative strength.

Counterevidence and next checks. This update is invalidated if the remaining Senate calls block a Democratic majority, Nasdaq futures recover, and Tokyo's semiconductor leaders reclaim VWAP with broader market breadth. The opposite case strengthens if further Republican-held Senate seats flip, the Nikkei remains near the morning low, and the yen appreciates while U.S. futures stay weak.

Market observation: 4 Nov 2026, 09:36–09:40 JST
Data status: Intraday TradingView screen records, not official closing prices

What changed. The pre-open thesis expected AMD and Arista Networks to cushion the Asian semiconductor shock. Tokyo rejected that thesis in the first forty minutes. At 09:40, the electronic-technology heatmap showed Kioxia −7.40%, Advantest −4.47%, Murata −4.38%, Renesas −4.23%, Lasertec −3.14% and Ibiden −2.27%. In production goods, Tokyo Electron was −3.46%, Disco −6.17%, Fujikura −5.64% and Sumitomo Electric −4.66%. The Nikkei 225 screen was at 62,151.71 and TOPIX at 3,913.66 around 09:36.

Why it matters. AMD’s record quarter—revenue up 45% and data-center revenue up 97%—and Arista’s 58.5% revenue growth confirm strong AI-infrastructure demand. They did not create durable buying in the most crowded Japanese beneficiaries. This is evidence of a valuation, positioning and liquidity reset; it is not evidence that AI end demand disappeared overnight.

Kioxia was the stress centre. At 09:38, Kioxia traded at ¥10,510, below its displayed VWAP of ¥10,940 and about 3.93% below it. The five-minute ATR was ¥151.02, ATR% was 12.29% (“extremely high”), and RVOL was 1.14×. Price, volatility and turnover were aligned in the bearish direction. The day low of ¥10,480 is the first liquidation reference; ¥10,650 and VWAP ¥10,940 are the first recovery tests.

The Mitsubishi Electric exception weakened. The screener repeatedly identified Mitsubishi Electric before the five-minute bar closed, with Score 9 and Trade Ready 2. By 09:39, the stock was still up 3.28% on the heatmap, but had slipped to ¥4,917, below displayed VWAP ¥4,930. Relative strength survived; the clean intraday long signal did not. A scanner hit was a candidate for inspection, not an automatic trade.

Counterevidence. The tape was not uniformly red. Keyence was +0.71%, Nitto Denko +2.84%, Sony +0.48% and Mitsubishi Electric +3.28%. USD/JPY was around 158.329 and below its displayed VWAP of 158.481, so the weak-yen tailwind was not intensifying at that moment. These pockets argue for a crowded high-beta selloff rather than a total collapse in Japanese industrial demand.

Invalidation. The opening-liquidation thesis weakens if the Nikkei and TOPIX recover their opening ranges while Advantest, Tokyo Electron, Lasertec and Kioxia reclaim VWAP with improving breadth. It strengthens if rebounds fail below the lower volatility bands and the indices print new lows. For Mitsubishi Electric, ¥4,930 is the immediate VWAP test and ¥4,908 the observed intraday low.

Market event: U.S. cash close on 3 Nov 2026 and AMD earnings after the bell
Verified: 4 Nov 2026, 07:19 JST

What changed. The 3 November Asian close produced a bearish regional signal: Korea and Taiwan each lost about 3.6%. The subsequent U.S. session did not confirm a continuation of that selloff. The S&P 500 rose 0.36% and the Nasdaq 0.83%, while the Dow fell 0.38%. Nvidia gained 2.3%, Micron 2.6% and Apple fell 1.9%. The reversal was not broad: declining S&P 500 stocks outnumbered advancers by 1.6 to one, and six of eleven sectors fell.

AMD earnings. AMD reported third-quarter revenue of US\$13.38 billion, up 45%, with data-center revenue up 97% to a record US\$8.55 billion. Adjusted EPS was US\$2.09. The company guided fourth-quarter revenue to about US\$17 billion, plus or minus 3%, above the LSEG consensus of US\$16.23 billion. Shares rose more than 8% in extended trading. The result confirmed strong AI compute demand and directly contradicted the idea that the Asian selloff represented an immediate collapse in end demand.

The counterevidence remains material. AMD guided adjusted gross margin to about 55%, down from 56% in the third quarter. Client and gaming revenue fell 8%, and high-bandwidth memory remains supply-constrained. A strong revenue guide does not eliminate customer concentration, packaging supply or valuation risk.

Rates and FX. The U.S. 10-year Treasury yield rose about 5.4 basis points to 4.948%, and USD/JPY moved to about 158.72. This creates a mixed Tokyo transmission: a weaker yen can support exporters and the Nikkei, but a higher discount rate challenges high-duration growth shares and the exchange rate remains close enough to 160 to keep intervention rhetoric relevant. No new BOJ, Federal Reserve or Japan Ministry of Finance policy decision was identified after the prior check.

Tokyo transmission. The previous view is revised from “regional chip shock likely to dominate the Tokyo open” to “regional shock partly offset by a U.S. chip rebound and AMD's earnings confirmation.” Test equipment, semiconductor manufacturing equipment, memory, advanced substrates and optical interconnects may receive an opening rebound. That is not yet an all-clear signal: U.S. breadth was weak, AMD's move is after-hours, and election results were not available at verification time.

Counterevidence and next checks. Confirm whether AMD's after-hours gain survives the next cash session and whether buying spreads to Nvidia, Broadcom, Micron, the SOX and AI infrastructure. At the Tokyo open, distinguish the opening gap from durable demand by checking 09:05, 09:15 and 09:30 prices, VWAP and turnover. U.S. midterm election results remain pending and can change yields, the dollar and AI regulation expectations.
