Trump Crash-Lands in Tokyo—and Japan’s AI Trade Hits the Pavement

日本語 · English

At 9:32 a.m., the broad market was resilient. The semiconductor complex was still trapped under the wreckage.

Tokyo Morning Dispatch | November 5, 2026 | 9:33 a.m. JST

Wall Street celebrated political gridlock. Tokyo opened the morning by separating the winners from the wreckage.

Democrats had swept both chambers of Congress in a sharp repudiation of President Donald Trump. The broader global reaction was relief: divided government could mean fewer abrupt policy shocks. But the same election result also raised the prospect of tougher scrutiny for artificial intelligence, data centres and other politically exposed technology investments.

Japan did not import that story as a simple risk-off trade. It imported it as a rotation.

At 9:32 a.m., the TOPIX was near its morning high around 3,984, while the Japan 225 index was near 62,541. Banks, insurers, automobiles, retailers and large parts of the domestic economy were green. The damage was concentrated in the crowded artificial-intelligence and semiconductor complex.

That distinction matters. The market was not saying that Japan had suddenly become uninvestable. It was refusing to pay yesterday’s AI multiple uniformly.

The market split in two

The heatmap looked less like a national sell-off than a city with one district on fire.

Financials were broadly firm. Toyota Motor was up roughly 7.7%, and Sony Group was also up about 7.7%. The strength extended beyond two headline names: banks, insurers, retail and several consumer-facing groups were positive.

The electronic-technology block told the opposite story. At the 9:32 snapshot:

• Advantest was down about 8.1%.
• Kioxia Holdings was down about 6.4%.
• Murata Manufacturing was down about 7.4%.
• Ibiden was down about 11.7%.
• Lasertec was down about 8.2%.
• Tokyo Electron was down about 6.0%.

This is the key morning signal: breadth outside the AI supply chain remained alive, even as the most crowded technology exposures were repriced.

The wreckage was real—but not every rebound was equal

The five-minute charts showed three different conditions inside the semiconductor sell-off.

Advantest remained below its intraday volume-weighted average price, with weak internal scores and no confirmed reversal signal. Tokyo Electron showed the same basic structure: below its intraday average, weak participation and no validated recovery.

Kioxia Holdings was different. It had recovered above its intraday volume-weighted average price after the opening shock. That was evidence of attempted stabilisation, not proof of a durable reversal. The stock was still deeply negative on the day, and its internal momentum readings remained too weak to treat the bounce as a clean trend change.

In other words, the market had begun to sort the wreckage—but had not yet finished.

No signal is still information

The strict Core 30 momentum screen returned no matching stocks.

The filter required price to be above the 20-period moving average, time-adjusted relative volume above 1.2 times normal, a positive daily move, price above both the intraday volume-weighted average and the day’s opening price, a score above six, and a positive trade-readiness reading.

No company passed all of those conditions at once.

That does not mean there were no strong stocks in Japan. Toyota Motor and Sony Group were plainly strong on the heatmap. It means there was no clean, fully confirmed momentum-long setup inside the selected Core 30 universe under those strict rules at that moment.

For a trader, that is useful information. A dramatic green tile is not automatically a low-risk entry. Price can be strong while the timing is poor.

The political transmission from Washington to Tokyo

Reuters reported that investors broadly welcomed the Democratic sweep because a divided Washington could reduce the probability of sudden policy shocks. Yet the same result created a more difficult narrative for data-centre and AI-linked companies: tougher oversight, slower project approvals and more political scrutiny became plausible risks.

My interpretation is that Tokyo’s semiconductor sell-off was an extension of that global re-rating, amplified by crowded positioning. The evidence supports a sector-specific transmission, not a claim that one election result alone caused every decline.

The counterpoint is important. Weakness in AI-linked shares had begun before the vote, and some of the morning reaction may prove excessive. If political gridlock ultimately limits sweeping regulation, today’s sell-off could become a positioning reset rather than the start of a structural collapse.

For now, however, the burden of proof sits with the rebound.

The yen was not the rescue

The dollar was near ¥158.29 at 9:32 a.m., slightly below its intraday volume-weighted average but still firmly inside a weak-yen regime.

Normally, that backdrop can support Japanese exporters. This morning it helped explain why the broader market could remain resilient while technology names fell. But the weak yen was not enough to rescue the semiconductor complex from a valuation and policy shock.

That is another reason not to call this a uniform macro trade. Currency support and sector de-rating were happening simultaneously.

What would change the read

Three developments would materially improve the morning picture:

1. Nikkei 225 futures reclaiming the lower volatility band near 62,770, followed by the intraday volume-weighted average near 63,020.
2. Advantest and Tokyo Electron reclaiming their own intraday volume-weighted averages with rising volume—not merely printing small rebound candles.
3. Multiple companies beginning to pass the strict Core 30 momentum screen, showing that price strength, volume and trade readiness are finally aligning.

The bearish confirmation would be the opposite: failed rebounds in semiconductor leaders, futures remaining below the lower band, and the red technology block spreading into financials, autos and domestic demand.

TokyoBrainie’s view

This was not a morning to ask whether Japan was up or down. It was a morning to ask which Japan the market wanted to own.

The answer at 9:33 a.m. was clear: banks, autos, selected consumer businesses and domestic cyclicals could still attract capital. The AI infrastructure trade could not rely on yesterday’s prestige, political protection or valuation.

Trump may have crash-landed in Tokyo, but the city was not destroyed. One crowded neighbourhood was burning, while capital had already crossed the street.
