Nikkei Faces Dividend Test After Five-Day Rally

The final trading day for many September-end dividend rights is expected to shape the session. Investors who want to receive interim dividends or shareholder benefits for many companies with September 30 record dates must hold the shares through the September 28 close, making the day an important deadline for banks, insurers, trading houses, manufacturers and other high-dividend names.

That dividend demand helped broaden the market on September 25, when the Nikkei rose 850 points and TOPIX climbed 53.29 points to 4,128.59. Banks were the strongest sector, while semiconductor and AI-linked shares such as Tokyo Electron, Advantest, Kioxia and Ibiden lifted the Nikkei.

The immediate question for September 28 is whether that broad support can continue, or whether investors take profits before the September 29 ex-dividend adjustment. The Nikkei has already moved sharply from its mid-September lows, and the dividend calendar may encourage both last-minute buying and caution over what happens once the rights date passes.

The Nikkei’s technical picture has improved. The index reclaimed 65,000 after Silver Week and then moved above 66,000 on September 25, supported by chip shares, banks and renewed confidence in global AI demand.

The next test is whether the Nikkei can hold above 66,000 and make another attempt toward the upper 66,000 range. A firm close would suggest that the rebound has moved beyond a short-term futures-led recovery. A weak session would raise the risk that the recent rally was driven partly by dividend demand and short covering.

TOPIX will be just as important as the Nikkei. On September 24, the Nikkei rose while TOPIX slipped, showing a narrow AI-led rally. On September 25, TOPIX rose strongly as banks and dividend-sensitive shares joined the advance. For September 28, investors will watch whether that broader participation continues.

A market led only by Tokyo Electron, Advantest and SoftBank Group can lift the Nikkei quickly, but it remains vulnerable to profit-taking. A stronger TOPIX would suggest healthier demand across financials, exporters, value shares and domestic-demand names.

The dividend theme should keep banks in focus. Mitsubishi UFJ Financial Group, Sumitomo Mitsui Financial Group, Mizuho Financial Group, Resona Holdings and regional banks attracted buying on September 25 as investors positioned for interim dividends and higher interest rates.

Banks remain one of the clearest beneficiaries of BOJ normalization because higher rates can improve lending margins and investment income. However, the sector has already priced in a significant amount of rate-hike optimism, so the next stage depends on whether investors believe the BOJ will raise rates again in December or early 2027.

The BOJ raised its policy rate to 1.25% on September 18, the highest level in 31 years. The market initially treated the decision as less hawkish than feared because of the split vote and cautious guidance, which weakened the yen and supported equities.

That reaction remains important for September 28. If investors continue to see the BOJ as gradual rather than aggressive, growth and technology shares may stay supported. If bond yields rise again or BOJ officials sound more hawkish, rate-sensitive sectors could face pressure.

Japanese government bond yields remain one of the biggest risks. The 10-year yield has moved above 3% and touched around 3.121%, its highest level since 1996. That changes the investment environment for equities, banks, insurers, mortgages, corporate borrowing and government finances.

Higher yields support financial shares, but they pressure high-valuation growth stocks by raising the discount rate applied to future earnings. They also increase the government’s debt-servicing burden, making fiscal discipline a larger issue for investors.

For September 28, the bond market will be a key guide. A stable or slightly lower JGB yield would help equities, especially semiconductor and AI-related shares. A renewed rise in 10-year or super-long yields would raise concern that the rally is running into a higher-rate ceiling.

The yen is another central signal. The dollar-yen rate has been trading near the 158 range, leaving the currency weak even after the BOJ’s rate hike. That supports exporters but keeps imported-inflation and intervention risks alive.

A weaker yen helps automakers, machinery makers, electronics companies and precision-equipment manufacturers by increasing the yen value of overseas earnings. It also supports the Nikkei because many large exporters and technology companies benefit from overseas revenue translation.

However, yen weakness remains a burden for households and importers. It raises the cost of energy, food, raw materials and consumer goods, especially when oil prices remain elevated.

Finance Minister Satsuki Katayama has kept currency stability in focus, and markets remain alert to intervention risk if the yen moves quickly toward 160. A sudden move in dollar-yen could quickly affect sentiment on September 28.

For exporters, Toyota, Honda, Sony Group, Fanuc, Keyence, Komatsu and precision-equipment makers will be watched closely. A stable weak yen could support them, while a sharp yen rebound would likely revive earnings concerns.

Honda may remain in focus after recent buying linked to its next-generation hybrid vehicle strategy in North America. Automakers remain sensitive to the yen, U.S. demand, tariffs and the balance between hybrid and electric vehicle investment.

The AI and semiconductor trade will remain the main driver of the Nikkei. Tokyo Electron and Advantest were the two most important contributors to the September 25 rally, while Kioxia, Ibiden, Murata Manufacturing, TDK, Taiyo Yuden, Lasertec, Screen Holdings and other chip-related names also drew attention.

U.S. technology shares finished higher on September 25, with Microsoft rising after unveiling new Copilot-related AI capabilities. That provides a positive overseas lead for Japanese AI and software-related names, although the rally in U.S. stocks was not as powerful as the earlier surge seen during Japan’s Silver Week break.

The Philadelphia Semiconductor Index had weakened earlier in the week, but Japanese chip shares still rose on September 25. That suggests domestic factors, including the weak yen, dividend demand and positioning, were stronger than the overnight U.S. chip lead.

For September 28, investors will watch whether Japanese semiconductor stocks can keep rising without a fresh U.S. catalyst. If Tokyo Electron and Advantest continue to gain, the Nikkei may remain firm. If they fade, the index could struggle even if TOPIX is supported by dividend buying.

Kioxia remains a key barometer for memory-sector confidence. The company is tied to high-bandwidth memory, AI servers and data-center storage demand, but its share price has been highly volatile since July. Strength in South Korean memory shares would support sentiment, while weakness in Samsung Electronics or SK Hynix would likely weigh on Tokyo’s chip complex.

Fujikura, Furukawa Electric and Sumitomo Electric remain important second-wave AI infrastructure names. Their exposure to optical fiber, cables, high-speed networks and data-center infrastructure keeps them closely tied to the physical buildout required by artificial intelligence.

SoftBank Group will also be closely watched. The stock did not fully join the September 25 rally because of concern over delays in Oracle data-center power supply projects, but it remains Tokyo’s most visible proxy for global AI investment through its exposure to OpenAI, Arm, robotics and digital infrastructure.

SoftBank’s funding plans remain important because the scale of its AI strategy depends heavily on capital-market access. A recovery in the stock would support the Nikkei, while renewed weakness would limit the index’s upside even if chip-equipment shares stay firm.

The AI trade is still powerful, but investors are now more selective. They are separating chip equipment, memory, optical fiber, platforms, software and data-center infrastructure according to earnings visibility, valuation, funding needs and exposure to bottlenecks such as power supply.

Oil will remain a major macro factor. Crude prices have eased from recent highs, helping reduce inflation pressure, but energy costs remain high enough to affect Japan’s trade balance, household budgets and corporate margins.

Japan imports most of its energy, so oil prices feed directly into gasoline, electricity, aviation fuel, shipping, logistics, chemicals and manufacturing. A further decline in crude would support Japanese equities and household sentiment. A rebound would revive inflation concerns, especially with the yen near 158.

Households remain under pressure despite improving wages. Consumers still face high costs for groceries, gasoline, electricity, transport and services. That means retailers, restaurants, travel companies and consumer-product makers remain sensitive to whether wage gains are enough to cover rising everyday expenses.

For companies, the key issue remains pricing power. Firms with strong brands, stable demand, recurring revenue or exposure to long-term investment are better positioned. Companies without pricing power face margin pressure if wages, energy, logistics and borrowing costs keep rising.

The September 28 session may also show whether investors continue rotating into value and dividend shares. Trading houses, insurers, banks, telecoms and manufacturers with strong payouts could attract demand through the close, but the ex-dividend adjustment on September 29 may make investors cautious about chasing prices too aggressively.

Mitsubishi Corp., Mitsui & Co., Itochu, Sumitomo Corp. and Marubeni remain important gauges of value and shareholder-return demand. They have lagged some AI names recently, but dividend buying and commodity exposure could support them if investors seek balance after the Nikkei’s fast rally.

Insurers such as Tokio Marine and MS&AD remain tied to the yield story. Higher rates can improve investment returns, but rapid bond-market moves can also create volatility in portfolios.

Retailers and importers remain more complicated. A weak yen hurts import costs, but easing oil can help. Nitori and similar yen-benefit names may struggle if dollar-yen remains near 158, while companies with strong domestic pricing power may fare better.

Prime Minister Sanae Takaichi’s government remains part of the market backdrop. The government is trying to support households, increase defense spending and fund long-term strategic investment while bond yields and debt-servicing costs rise.

The government’s growth strategy targets large-scale public and private investment through fiscal 2040 in semiconductors, artificial intelligence, energy security, defense, shipbuilding, robotics, space and other strategic sectors.

That strategy supports many of the companies leading the market, including chip-equipment makers, materials suppliers, optical-network firms, power-system companies, data-center infrastructure providers and defense-related manufacturers.

However, higher interest rates make fiscal discipline more important. Investors will continue watching budget discussions, debt-service assumptions and whether strategic investment can be funded without undermining confidence in public finances.

The international backdrop remains mixed. U.S. stocks rose on September 25 as AI optimism helped offset concern over oil prices and Treasury yields, but the week was volatile because of uncertainty over AI winners and losers, Middle East risks and high U.S. yields.

The U.S. Federal Reserve remains committed to fighting inflation, and markets continue to watch the possibility of another rate increase. High U.S. yields support the dollar and complicate the BOJ’s effort to stabilize the yen.

If U.S. yields keep rising, Japanese stocks may face two opposing forces: exporter support from a weaker yen, but valuation pressure from higher global bond yields. That tension is likely to remain a central theme on September 28.

U.S.-China relations also remain important after the latest Trump-Xi meeting produced symbolism but no major breakthroughs on AI, trade, Taiwan or the Iran conflict. Japanese exporters and technology companies remain exposed to any shift in U.S.-China supply-chain policy.

South Korean semiconductor shares will be another early indicator. Overseas investors increasingly treat Japanese chip-equipment makers, South Korean memory producers, Taiwanese foundries and U.S. AI shares as one connected technology trade.

If Seoul opens firm, Japanese AI and chip names may receive another boost. If Korean memory shares weaken, Tokyo’s semiconductor complex could face profit-taking.

What to watch on September 28: whether the Nikkei can hold above 66,000, whether TOPIX continues to catch up, whether dividend buying supports banks and value shares, and whether semiconductor shares can extend gains without a strong new U.S. chip lead.

The yen near 158 to the dollar remains the most important domestic market signal. A move toward 160 would support exporters but revive intervention and inflation concerns. A rebound toward 153 would ease import costs but pressure exporters and carry trades.

JGB yields are the second key signal. A stable 10-year yield would support the rally, while another rise toward fresh multi-decade highs would pressure growth shares and raise fiscal concerns.

The third signal is breadth. If banks, insurers, trading houses, exporters and domestic-demand shares rise alongside semiconductor names, the rally will look healthier. If gains narrow again to Tokyo Electron, Advantest and a few AI-linked names, the market will remain vulnerable.

September 28 is likely to be shaped by the collision of three forces: dividend buying before the rights deadline, momentum from AI and semiconductor shares, and caution over the weak yen and high bond yields. The Nikkei enters the session with strong upward momentum, but the market’s durability will depend on whether TOPIX can keep pace and whether buying survives beyond the dividend calendar.
