Nvidia’s Beat Lifts Tokyo—
Then Advantest Erases the Rally

Market Snapshot

Data checked: August 27, 2026 at 1:00 p.m. JST / August 26, 2026 at 9:00 p.m. PDT.

Nvidia delivered the kind of result that ordinarily gives Tokyo’s semiconductor complex a clean signal: quarterly revenue of $96.2 billion, data-center revenue of $89.0 billion and another sharply higher sales forecast. The first reaction looked textbook. The Nikkei opened 513.62 points above Wednesday’s close and reached 66,954.69 at 9:06 a.m. Six minutes into the session, however, a powerful rally became a contest between strong results and even stronger expectations.

The Nikkei fell to 65,782.59 by 10:13, producing a 1,172.10-point high-to-low range in little more than an hour. It recovered to 66,164.19 at the 11:30 morning close, down 0.15%, while TOPIX held a 0.09% gain. A separate official Nikkei reading at 12:53 showed 66,437.77, up 175.61 points or 0.27%. That late pulse is useful evidence of a second recovery, but it must not be mistaken for a synchronized 1:00 p.m. reading of TOPIX, breadth, the yen and bonds.

What Moved Tokyo

Wednesday: a broad rise with one unusually large engine

Tokyo ended August 26 with a measured advance. The Nikkei rose 405.73 points and TOPIX gained 0.42%; 978 Prime Market issues advanced. Lower oil prices, a small retreat in domestic yields and gains in U.S. shares supplied a favorable background, while investors waited for Nvidia’s report. The breadth says the rise was genuine. The contribution table says its headline size depended heavily on one stock.

Advantest rose 3.63% to ¥35,700 and added 301.70 points to the Nikkei. That is roughly 74% of the index’s entire 405.73-point advance. SoftBank Group contributed about 61.14 points and Recruit Holdings 55.31. Because the Nikkei is price-weighted, a large move in a high-priced constituent can overwhelm the visual message even when the broader market moves more quietly.

Thursday: the result was excellent; the price reaction was conditional

Nvidia’s fiscal second-quarter revenue rose 106% from a year earlier to $96.221 billion. Data-center revenue climbed 117% to $89.0 billion, and the company projected third-quarter revenue of $108 billion, plus or minus 2%. Those figures initially validated the global AI capital-spending story. They did not settle how much of that success was already embedded in Japan’s most expensive beneficiaries, or how future component costs and supply limits would affect margins.

At the 11:30 close, Advantest had fallen 2.30% to ¥34,880 and removed 197.91 points from the Nikkei. Fast Retailing, SoftBank Group, Chugai Pharmaceutical and KDDI were also drags. Yet Kioxia Holdings added 72.51 points, Fujikura 31.18, Ibiden 29.83, TDK 24.14 and Tokyo Electron 22.12. The market did not reject AI. It distinguished memory, optical networks, packaging materials, components, equipment and testing—and repriced each layer separately.

Advantest supplied nearly three quarters of Wednesday’s Nikkei gain, then removed almost 198 points by Thursday’s morning close. The two-day headline was less a national-market verdict than a one-stock round trip inside the AI trade.

Today’s Market Mover

Advantest began in 1954 as Takeda Riken Industry, entered semiconductor testing in 1972 and adopted its current name in 1985. Its place in the AI chain is unusually direct. More complex accelerators and high-bandwidth memory need more exacting tests, and rising device value increases the cost of allowing defects to pass. The company is therefore a proxy not merely for chip volume, but for chip complexity.

Its own July 29 forecast reinforced the structural case. Advantest said test demand for inference-oriented AI semiconductors was running above its April assumptions and raised its fiscal-year sales forecast to ¥1.714 trillion from ¥1.420 trillion. The operating-profit forecast rose to ¥846 billion from ¥627.5 billion. Those are company forecasts, not guarantees, but they explain why expectations were already so elevated before Nvidia reported.

The responsible explanation is therefore narrower than “Nvidia disappointed.” It did not. The verified fact is the share-price reversal and its index impact. Profit taking, crowded positioning and a hurdle set above the published result are plausible explanations, but without a company announcement or confirmed order change they remain attributed market interpretation.

Sector Pulse

Only 12 of 33 sectors advanced by the morning close, and Prime Market decliners outnumbered gainers 837 to 652. That breadth is more cautious than the nearly flat TOPIX suggests. Still, the strongest groups do not describe a broad flight from risk: nonferrous metals, mining, electric appliances and securities/commodity futures all rose.

The semiconductor complex split by business model. Memory maker Kioxia, optical-cable leader Fujikura, substrate and package supplier Ibiden, component maker TDK and equipment producer Tokyo Electron all made positive Nikkei contributions. The test-equipment leader moved the other way. For investors reading industrial demand, that divergence is more informative than calling the entire group “chips.”

Yen Watch

USD/JPY was near ¥159.36 around 11:35 a.m., firmer for the dollar than the Bank of Japan’s ¥159.00–02 reference at 5:00 p.m. Wednesday. The move was orderly, but the level keeps imported inflation, household purchasing power and official communication in the equity conversation. In New York, the pair had traded around ¥159.37 after a stronger-than-expected U.S. inflation reading.

July U.S. personal-consumption-expenditure inflation was reported at 3.7% year on year, against a 3.6% market expectation. The U.S. 10-year Treasury yield rose to about 4.668%. Together, those readings reduced the ease with which markets could assume quick Federal Reserve relief. For Tokyo, that supports the dollar against the yen and helps exporters’ translated earnings, but raises the domestic cost of energy and materials.

Rates / JGB Watch

The new benchmark 10-year JGB yield was 2.895% around 11:00 a.m., one basis point above Wednesday’s 2.885% close. September long-JGB futures slipped 0.06 to 126.42. The scale of the move was modest; the significance lies in its proximity to 3% and in its timing alongside Deputy Governor Ryozo Himino’s Saitama speech.

Higher yields can improve reinvestment income at banks and insurers, but they also raise discount rates, mortgage costs and corporate funding hurdles. For the AI beneficiaries that derive a large portion of their valuation from distant earnings, a near-3% domestic benchmark matters even when a U.S. earnings release dominates the morning headlines.

Wednesday’s five-basis-point decline was only half a basis point, not a change in regime. Thursday’s one-basis-point rise likewise does not establish a new trend. The next durable signal will come from auction demand, the yen, domestic inflation breadth and the Bank of Japan’s willingness to keep adjusting accommodation.

Global Handoff

Wall Street finished almost unchanged on August 26 before Nvidia reported. The Dow fell 113.52 points, or 0.21%, to 53,463.88; the S&P 500 slipped 0.02% to 7,675.70; and the Nasdaq Composite lost 0.08% to 26,130.20. Nvidia shares first fell more than 1% after hours, then reversed to a gain approaching 5% as investors parsed the scale of the beat and the outlook.

Oil remained an important Japanese input. West Texas Intermediate settled near $82.23 and Brent near $87.84. Lower energy prices than earlier in the week improve Japan’s terms of trade, but the yen near 159 means imported costs remain sensitive to both commodity and currency moves.

European cash markets had not opened by the 1:00 p.m. Tokyo production cutoff. The next handoff therefore runs through European technology suppliers, U.S. semiconductor trading and the August 27–29 Jackson Hole gathering. Federal Reserve Chair Kevin Warsh is scheduled to speak August 28; his inflation and rate language could travel back into Tokyo through Treasury yields, USD/JPY and growth-stock valuation.

Policy / BOJ Watch

Bank of Japan Deputy Governor Ryozo Himino delivered a speech titled “Japan’s Economy and Monetary Policy” at a meeting with business leaders in Saitama on Thursday morning. His message preserved the BOJ’s conditional tightening path: financial conditions remain accommodative even with the policy rate at 1%, and if the outlook is realized, the Bank expects to continue raising the policy rate and adjusting the degree of monetary accommodation.

Himino also said policymakers must pay increasing attention to the risk that underlying inflation exceeds 2%. The timing and pace are not precommitted. He identified the Middle East, AI demand, foreign exchange and the broader outlook as variables that could alter the path. The speech is therefore neither a date-specific hike signal nor a retreat from normalization.

One passage connected directly to the morning’s equity story. Strong AI-related demand is helping offset the deterioration in Japan’s terms of trade caused by oil, and Himino said its economic reach appears broader than previously thought. Yet the weak yen distributes benefits unevenly: exporters and inbound tourism gain, while households and smaller companies face higher real costs. Markets are pricing the same AI boom twice—once through earnings, and once through inflation and policy.

Publisher’s Market Note

A record supplier result did not fail. A crowded price briefly failed to carry it. That distinction is the difference between reporting an earnings fact and narrating a market reaction.

The cleanest two-day signal is Advantest’s contribution. It accounted for roughly three quarters of Wednesday’s Nikkei rise, then erased nearly 198 points Thursday morning. TOPIX stayed positive while the Nikkei slipped, and several other AI-linked names rose. The correct conclusion is not that Tokyo rejected Nvidia’s report. It is that the price-weighted Nikkei amplified a rotation within the AI supply chain.

The second signal is policy. AI demand can raise Japanese export income, lift capital spending and improve pricing power. It can also strengthen the case for continued normalization if the demand shock broadens inflation. Himino’s speech put those channels in the same frame. Earnings and interest rates are not separate stories; they are rival claims on the same valuation.

Before the Next Open

1. Thursday’s 3:30 p.m. close. Does the Nikkei retain the 12:53 recovery, and does TOPIX finish ahead of the price-weighted benchmark?
2. Advantest after the reversal. Watch whether ¥34,880 becomes a point of renewed demand or whether profit taking broadens after Wednesday’s 3.63% rise.
3. AI-chain breadth. Kioxia, Fujikura, Ibiden, TDK and Tokyo Electron need to remain firm if the market’s message is rotation rather than rejection.
4. USD/JPY near ¥160. Speed, not only level, will shape exporter support and the risk of a sharper official response.
5. The 10-year JGB near 2.90%. Watch banks and insurers against high-multiple growth shares, and wait for later clarification of Himino’s message.
6. Nvidia’s U.S. cash-session reaction. After-hours gains can change once full liquidity returns and analysts test guidance, margins and supply constraints.
7. Jackson Hole and U.S. rates. Warsh’s scheduled August 28 remarks can reset the Treasury-dollar channel before Tokyo’s next session.
