J.P. Morgan Raises Japanese Stock Targets—AI Supercycle Fuels Continued Bull Run

Overview

J.P. Morgan's Japanese equity strategy team released its outlook for the second half of the year, maintaining a bullish stance on the Japanese stock market and raising year-end targets. The report argues that driven by the global AI supercycle, the Japanese stock market performed strongly in the first half, with the Nikkei 225 rising by 39%, significantly outperforming major global indices. Although the pace was fast, corporate earnings growth exceeded expectations, valuations have cooled somewhat, and structural changes (corporate reforms, capital inflows) coupled with the tailwind from the AI semiconductor cycle leave room for further upside in the second half.

Core views

The report's core view is that the Japanese stock market will continue its upward trend in the second half of 2026, with the main driver shifting from policy expectations to earnings growth. Index performance and target prices: In the first half, TOPIX rose 18% year-on-year, outperforming the MSCI World, S&P 500, and STOXX 600 indices. Since April, AI semiconductor stocks have led the market rebound, with the Nikkei 225 rising 39% year-to-date, significantly outperforming TOPIX (AI-related stocks account for about 50% of the Nikkei 225’s market cap and about 30% of TOPIX). Given that the global AI supercycle is progressing faster than expected, J.P. Morgan raised its year-end targets to 75,000 points for the Nikkei 225 and 4,400 points for TOPIX. As of mid-June, the Nikkei 225 had already reached its earlier mid-year target, leaving TOPIX with about 7-8% upside remaining. Earnings and valuation: Semiconductor and semiconductor equipment companies (SPE), such as Kioxia and wire and cable manufacturers, reported strong earnings growth. The FY2026 TOPIX EPS forecast was raised from 198 yen at the end of 2025 to 234 yen (+11% year-on-year). On the valuation front, the P/E ratio has cooled to around 16x, easing overheating concerns. The report sees upside risk in earnings growth. Allocation strategy for the second half: AI semiconductors and the financial sector are seen as core components of Japanese equity portfolios. If the Middle East situation stabilizes, sectors like construction, transportation, chemicals, and defense could see short-term rebounds due to falling oil prices. The food sector is also expected to recover, as rising crude oil prices may be passed onto consumers and the food consumption tax is likely to be reduced in summer. During the first-half earnings season in autumn, upward revisions in earnings forecasts for large banks, automakers, and defense firms could drive stock price rebounds, potentially leading to some correction in the AI-dominated market by year-end. It's worth noting that within the AI semiconductor sector, there are signs of divergence—SPE and memory manufacturers are expected to exceed earnings forecasts, while lagging areas like physical AI still have room for catch-up growth.

Analysis framework

The report adopts a top-down macro strategy analysis framework, combining an earnings-driven model with valuation multiples to derive index target prices. The specific analytical path is as follows: First, starting from the global macro environment, we identify the AI supercycle as the core driver, especially the demand for AI inference and U.S. hyperscale data center investments, which boost demand for semiconductor chips, memory, and electronic components. Second, comparing the AI exposure differences between Japan's two major indices (about 50% for Nikkei 225 vs. about 30% for TOPIX), we explain the structural reasons behind the divergent gains. Then, through revised EPS forecasts and dynamic adjustments to P/E valuations, we validate the fundamental support for the market rally—raising FY2026 EPS from 198 yen to 234 yen and observing the P/E ratio fall from high levels to 16x, indicating that overheating risks have eased. Finally, at the sector level, we adopt a 'core plus satellite' allocation logic: using AI semiconductors and finance as base holdings, while also allocating to cyclical sectors that could rotate (construction, transportation, chemicals, defense, food), and paying attention to opportunities arising from better-than-expected earnings.

Methodology notes

• Valuation MethodPE/PEG valuation

  P/E valuation multiple method: Deriving index target prices by multiplying the predicted next 12-month earnings (NTM EPS) by the target P/E multiple

  In the report, J.P. Morgan uses TOPIX's 12-month forward P/E (17x) multiplied by the predicted EPS (262 yen) to arrive at a target price of 4,400 points. This is the most common index pricing method used in strategy research, with the core assumption being the stability of the valuation center.

• Industry/Industrial Analysis FrameworkUpstream-Midstream-Downstream Industry Chain Transmission

  AI industry chain transmission analysis: From downstream applications (AI inference) → midstream infrastructure (data centers) → upstream hardware (chips, memory, equipment) demand transmission

  The report identifies that in the AI supercycle, U.S. hyperscale enterprises’ data center investments act as a demand amplifier, boosting orders and earnings for Japanese semiconductor equipment, storage chip, and electronic component companies. This cross-border capacity chain analysis helps pinpoint the benefiting segments for Japanese companies.

• Cycle and Economic Sentiment FrameworkEconomic Turning Point Analysis

  Earnings forecast revision as an economic sentiment indicator: Tracking the direction of consensus EPS forecasts to gauge industry economic positions

  The report raised the FY2026 EPS forecast from 198 yen to 234 yen, taking it as evidence that the semiconductor cycle is stronger than expected. At the same time, the P/E ratio falling from high levels validates that the market is not overheated—a typical 'earnings validation + valuation confirmation' dual framework.

• Quantitative/Factor/Portfolio TheoryBeta/alpha analysis

  Index beta and industry exposure analysis: By dissecting the differences in AI exposure among indices, explaining the divergence in gains between Nikkei 225 and TOPIX

  The report notes that AI-related stocks account for about 50% of the Nikkei 225, while TOPIX has only about 30%. This structural difference gives the Nikkei 225 a higher beta elasticity in the AI-themed rally, which is a key quantitative perspective for understanding the performance gap between the two.

Impact & implications

The report believes that the Japanese stock market’s upward momentum is shifting from policy expectations to earnings-driven growth. Structural changes (corporate reforms improving balance sheets and profitability, inflows of funds from individual investors, pension funds, and financial institutions) combined with the AI semiconductor cycle are resonating enough to offset negative factors such as inflation, rising interest rates, and yen depreciation. If the Middle East situation stabilizes in the second half, sector rotation could spread from AI semiconductors to cyclical sectors like finance, automobiles, and defense—but AI remains the main theme. For investors, the key is to seize differentiated opportunities within the AI industry chain—SPE and memory manufacturers are expected to exceed earnings forecasts, while lagging areas like physical AI still have room for catch-up growth.

Risks

• Excessive yen depreciation: A yen-dollar exchange rate below 160 would negatively impact household sectors due to heightened transmission effects that fuel domestic inflation, while also hurting overseas investors’ equity returns
• Sharp rise in interest rates: The Bank of Japan might accelerate rate hikes, and if the Fed under Chairman Powell takes a tougher stance, it could trigger market volatility
• Geopolitical risks: Global geopolitical uncertainties, including the Middle East situation, remain major concerns for the second half
• Fiscal expansion worries: The market is concerned that fiscal expansion could push long-term interest rates higher, but the report believes that in an inflationary environment, it won’t immediately cause runaway spikes

What to watch

• Second-half inflation trends and the Bank of Japan’s rate hike pace
• Fed policy shift and its impact on the yen exchange rate
• Middle East developments and their impact on oil prices and related sectors
• Revisions in earnings forecasts for large banks, automakers, and defense firms during the first-half earnings season in autumn
• Divergence in overheating signals within the AI semiconductor sector, particularly the earnings realization of SPE and memory manufacturers
• Catch-up opportunities in lagging areas like physical AI
• Specific progress on the food consumption tax reduction policy
