TOKYO –
Tokyo shares surged on October 1, with the Nikkei 225 closing at 68,957, up 2,203 factors, as traders rushed again into synthetic intelligence and semiconductor-related shares after Micron Technology’s sturdy earnings outlook bolstered confidence in world chip demand.
The rally lifted the Nikkei above 68,000 for the primary time in about six weeks and marked one of many sharpest rebounds of the latest AI-driven market cycle. The transfer adopted a robust September 30 rally, extending the market’s restoration from the ex-dividend decline earlier within the week.
The broader market was a lot much less highly effective than the Nikkei. TOPIX lagged as banks, insurers, buying and selling homes and different worth shares got here underneath strain, displaying that the day’s advance was closely concentrated in high-priced expertise and semiconductor names.
The Nikkei opened greater at 67,107 and rapidly accelerated as traders purchased chip-related shares. By late morning, the index was above 68,000, and shopping for continued by a lot of the session because the market adopted the lead from U.S. expertise shares and Micron’s upbeat outlook.
The day’s transfer reversed the warning that had dominated September 28 and September 29, when traders took income after the Nikkei briefly topped 67,000 after which confronted the mechanical drag from the September-end ex-dividend adjustment.
The October 1 rally was completely different in scale. It was pushed by renewed confidence that AI-related demand stays sturdy sufficient to assist earnings throughout the worldwide semiconductor chain, from reminiscence chips to testing tools, manufacturing instruments, digital elements and data-center infrastructure.
Micron Technology was the principle catalyst. The U.S. memory-chip maker reported sturdy outcomes and gave an outlook that exceeded market expectations, reinforcing the view that AI servers, high-bandwidth reminiscence and data-center funding proceed to drive demand.
That instantly supported Japanese names tied to reminiscence, chip tools and AI infrastructure. Investors handled the Micron news as affirmation that the AI cycle nonetheless has earnings energy, not simply market enthusiasm.
Advantest was one of the vital vital drivers of the Nikkei’s rise. The chip-testing tools maker stays one in every of Japan’s clearest beneficiaries of superior AI processor demand and high-performance computing funding.
Because of its heavy weighting within the price-weighted Nikkei, Advantest can transfer the headline index sharply. Its energy on October 1 helped clarify why the Nikkei surged although the broader market was much more combined.
Tokyo Electron additionally rose strongly. The semiconductor-equipment maker stays central to Japan’s function in world chip manufacturing and continues to learn when traders change into extra assured about capital spending by semiconductor producers.
ComfortableBank Group was one other main assist. The firm stays Tokyo’s most seen proxy for world AI funding by its publicity to OpenAI, Arm, robotics, digital infrastructure and different large-scale expertise platforms.
ComfortableBank’s acquire confirmed that traders have been once more keen to purchase long-duration AI progress publicity, even with world bond yields nonetheless excessive. That was an vital change from late September, when rising yields and funding issues had stored traders extra cautious towards the stock.
Kioxia Holdings additionally drew consideration after Micron’s outcomes strengthened confidence within the reminiscence cycle. Kioxia stays one in every of Tokyo’s key gauges of demand for high-bandwidth reminiscence, AI servers and data-center storage.
The reminiscence theme has been unstable since July, however the October 1 session confirmed that traders nonetheless see Kioxia as a serious beneficiary when world AI {hardware} demand improves.
Ibiden, Lasertec, Screen Holdings, SUMCO, Murata Manufacturing, TDK, Taiyo Yuden, Fujikura, Furukawa Electric and Sumitomo Electric additionally remained central to the day’s market story. These corporations cowl superior substrates, semiconductor tools, wafers, digital elements, optical fiber, cables and data-center infrastructure.
The energy in these names confirmed that traders have been once more shopping for the complete AI provide chain, not solely a handful of headline chip shares. Still, the market’s focus remained clear: the Nikkei surged as a result of a small variety of high-impact AI and semiconductor shares rose sharply.
The divergence with TOPIX was vital. While the Nikkei rallied greater than 3%, the broader index struggled as a result of financials, buying and selling homes and different worth sectors weakened. That meant the market was not making a broad risk-on transfer throughout all sectors.
Banks and insurers have been underneath strain as bond-market volatility and profit-taking weighed on latest winners. Financial shares had been supported by expectations for greater Japanese rates of interest, however traders rotated away from them on October 1 as cash moved again into AI and semiconductor shares.
Mitsubishi UFJ Financial Group, Sumitomo Mitsui Financial Group, Mizuho Financial Group, Resona Holdings, Tokio Marine and different monetary names stay vital gauges of the higher-rate commerce. Their weak spot confirmed that traders have been shifting from dividend and rate-sensitive worth shares into progress and expertise.
Trading homes additionally confronted promoting. Mitsubishi Corp., Mitsui & Co., Itochu, Sumitomo Corp. and Marubeni had been vital worth and shareholder-return performs, however they lagged as traders targeting AI-related momentum.
Pharmaceuticals and a few defensive shares have been additionally weak. That instructed traders have been shifting away from security and earnings themes and again into progress sectors linked to U.S. expertise demand.
The Bank of Japan’s Tankan survey added one other layer to the market. Business confidence improved to its strongest degree in eight years, supported by agency company earnings, value will increase and resilience in elements of the manufacturing sector.
The Tankan consequence strengthened the argument that Japan’s financial system stays resilient sufficient for the BOJ to proceed normalizing financial coverage. That is optimistic for the long-term Japan funding story, but it surely additionally retains rate-hike strain alive.
The BOJ raised its coverage fee to 1.25% on September 18, the very best degree in 31 years. Markets at the moment are centered on whether or not the central financial institution will elevate charges once more in December or early 2027.
The Tankan makes that query extra pressing. Stronger enterprise confidence provides Governor Kazuo Ueda extra proof that corporations can stand up to greater borrowing prices, however the BOJ should nonetheless keep away from destabilizing the yen, bond market or equities.
Japanese authorities bond yields stay a serious threat. Global bond markets remained underneath strain on October 1, and yields in Japan have climbed to multi-decade highs. The 10-year JGB yield not too long ago moved above 3%, a degree not seen since 1996.
Higher yields are a combined power. They assist banks and insurers by bettering lending margins and funding returns, however they strain high-valuation progress shares by elevating the low cost fee utilized to future earnings.
On October 1, the AI earnings story was sturdy sufficient to beat the yield threat for expertise shares. But if JGB yields rise once more, the identical semiconductor names that led the rally might change into weak to valuation strain.
Higher yields additionally improve the federal government’s debt-servicing burden. Prime Minister Sanae Takaichi’s administration is attempting to assist households, improve protection spending and fund long-term strategic funding whereas sustaining fiscal credibility.
The authorities’s progress technique targets large-scale private and non-private funding by fiscal 2040 in semiconductors, synthetic intelligence, power safety, protection, shipbuilding, robotics, area and different strategic sectors.
That technique helps most of the corporations that rose on October 1, together with chip-equipment makers, electronic-component suppliers, optical-network corporations, power-system companies and data-center infrastructure suppliers.
However, greater rates of interest make the funding query harder. Investors need proof that Japan can assist family aid and industrial coverage with out undermining confidence in public funds.
The yen remained weak, buying and selling round 158 to the dollar. That supported exporters and helped the Nikkei, but it surely additionally stored imported-inflation and intervention dangers alive.
A weak yen helps automakers, equipment makers, electronics corporations and precision-equipment producers by growing the yen worth of abroad earnings. It additionally helps many Nikkei heavyweights with giant abroad income publicity.
For households and importers, nevertheless, yen weak spot is a burden. It raises the price of power, meals, uncooked supplies and client items, including strain to day by day bills.
The BOJ’s September fee hike has not decisively strengthened the yen as a result of the interest-rate hole between Japan and the United States stays large. The Federal Reserve’s coverage path is subsequently nonetheless central to Japan’s forex outlook.
U.S. inflation information eased some concern about an October Fed fee hike, and New York Fed President John Williams mentioned there was no urgency for additional motion. That helped assist U.S. expertise shares and decreased some strain on world progress shares.
However, U.S. Treasury yields remained excessive, limiting the profit. The world bond market stays tense as a result of traders are nonetheless involved about inflation, authorities borrowing and the price of financing giant deficits.
For Japan, excessive U.S. yields preserve the dollar supported. That makes it more durable for the yen to strengthen, even after the BOJ has begun elevating charges.
Oil costs remained one other key variable. Lower crude in latest periods has helped sentiment, however power prices are nonetheless excessive sufficient to have an effect on Japan’s commerce steadiness, company margins and family budgets.
Japan imports most of its power, so oil costs feed instantly into gasoline, electrical energy, aviation gas, transport, logistics, chemical substances and manufacturing. If crude rises whereas the yen stays close to 158, inflation strain might return rapidly.
Households stay underneath strain regardless of bettering wages. Consumers proceed to face excessive prices for groceries, gasoline, electrical energy, transport and providers.
The Tankan confirmed company confidence is powerful, however households decide the financial system in a different way. For customers, the principle subject stays whether or not wage beneficial properties can cowl on a regular basis prices.
Companies are nonetheless deciding how a lot of upper labor, logistics, supplies, power and borrowing prices might be handed on to clients. Firms with pricing energy, sturdy manufacturers, steady demand or publicity to long-term funding stay higher positioned.
Companies with out pricing energy face a harder setting. If the yen weakens additional, oil rises or customers resist value will increase, revenue margins might come underneath strain even when gross sales seem steady.
The October 1 rally subsequently had two sides. The AI and semiconductor story was extraordinarily sturdy, however the broader home financial system nonetheless faces strain from costs, yields and forex volatility.
The market’s breadth was additionally a warning signal. A sturdy rally would want stronger participation from banks, buying and selling homes, autos, industrials, retailers and domestic-demand shares. On October 1, the rally was led primarily by AI and semiconductor shares.
The Nikkei’s technical image improved sharply. The index not solely reclaimed 67,000 but additionally moved by 68,000, reversing the failed breakout seen on September 28.
The subsequent main take a look at is whether or not the Nikkei can maintain the 68,000 degree. A sustained transfer above that space would sign that the AI-led rebound has regained power. A fast reversal would recommend that the market stays depending on short-term momentum in a small variety of heavyweight names.
The 67,000 degree now turns into preliminary assist. The Nikkei failed there earlier within the week, so holding above it might strengthen confidence within the rebound.
TOPIX stays the important thing affirmation sign. If TOPIX begins to rise alongside the Nikkei, the rally will look more healthy. If TOPIX continues to lag or fall, traders might conclude that the advance is simply too slim.
The Growth Market 250 Index additionally stays price watching. Smaller progress shares are nonetheless delicate to greater yields, and their efficiency will present whether or not threat urge for food is broadening past large-cap AI names.
South Korean and Taiwanese markets will stay vital for Tokyo’s chip complicated. Overseas traders more and more deal with Japanese semiconductor tools makers, South Korean reminiscence producers, Taiwanese foundries and U.S. AI shares as one linked expertise commerce.
Strong South Korean semiconductor exports and agency reminiscence demand would assist Kioxia, Tokyo Electron, Advantest and associated Japanese names. Weakness in Samsung Electronics, SK Hynix or Taiwan Semiconductor Manufacturing Co. would rapidly have an effect on sentiment in Tokyo.
ComfortableBank’s function additionally stays central. If traders proceed to purchase AI platforms, Arm-related publicity and large-scale data-center funding, ComfortableBank might stay a serious Nikkei assist. If funding prices or power-supply issues return, the stock might once more change into a drag.
What to observe subsequent: whether or not the Nikkei can maintain above 68,000, whether or not TOPIX catches up, and whether or not semiconductor shopping for broadens past Advantest, Tokyo Electron and ComfortableBank Group.
Investors will monitor Kioxia, Ibiden, Lasertec, Screen Holdings, SUMCO, Murata Manufacturing, TDK, Taiyo Yuden, Fujikura, Furukawa Electric and Sumitomo Electric for indicators that the AI supply-chain rally has depth.
Banks and insurers may even stay vital. If financials stabilize whereas expertise shares keep agency, the market might construct a stronger base. If banks proceed falling, TOPIX might wrestle even when the Nikkei rises.
The yen close to 158 to the dollar stays a very powerful home sign. Further weak spot towards 160 would assist exporters however revive inflation and intervention issues. A rebound towards 153 would ease import prices however might strain exporters and carry trades.
JGB yields are the second key sign. A steady bond market would assist equities, whereas one other rise in 10-year or super-long yields would strain valuations and financial coverage.
Oil costs are the third sign. Lower crude would assist households and firms, whereas a renewed rise would intensify strain on Japan’s commerce steadiness and inflation outlook.
October 1 confirmed that the AI commerce stays highly effective sufficient to carry the Nikkei by greater than 2,000 factors in a single session. Micron’s outlook revived confidence in reminiscence and chip demand, and Japanese semiconductor shares responded sharply. But the hole between a surging Nikkei and a weaker broader market confirmed that Tokyo’s rally nonetheless wants wider participation earlier than it may be referred to as sturdy.
