[4-Layer Analysis] Viewing the Japanese Stock Market: Perspectives That Inform Investment Decisions and Reveal the Next Move

Thank you for visiting.

Today, Prime Minister Takaichi was inaugurated from President Takaichi. As Japan's first female prime minister in constitutional history, a female leader has been born ahead of the United States.

Prime Minister Takaichi majored in management mathematics at university. The policies being announced are based on solid economic and financial theory and information, and it is particularly reassuring that she has deep knowledge of science and technology. The birth of an administration that will put Japan on a growth trajectory and protect Japan from foreign forces has brought an unprecedentedly bright day. This will correct Japan's course in a direction that prevents its collapse.

Having overseas experience, my position is that Japan's reasonable conservatism is centrist by international standards and well-balanced. Real right-wing groups overseas are tremendously extreme, so Prime Minister Takaichi appears to me to be nothing more than a mainstream centrist as a Japanese person.

As for market movements, once news comes out, it's over, so this feels like a temporary profit-taking pullback.

Now, in this article, I've conducted a 4-layer analysis of the Japanese stock market, focusing on the Nikkei average. This is a comprehensive approach that analyzes four layers: market, policy, trade, and geopolitics—a new type of comprehensive analysis different from typical economic articles. Even when following news and social media, you often wonder, "So what does this all mean? Is now the time to buy? What will happen to US and Japanese stocks? What about the economy?"—There's so much similar information online, and even after reading it, you're left confused, right? This article aims to clear up that confusion by organizing various data points to reveal the next move.

Market Data Table

Comprehensive Report: "Nikkei Average 4-Layer Analysis (Market / Policy / Trade / Geopolitics)"

Overall Summary

The Nikkei Stock Average rose slightly to 49,316 yen (+0.27%). By sector, "Other Financials (+2.2%)" and "Services (+1.56%)" led gains, while export-related sectors like "Machinery (-3.26%)" and "Non-ferrous Metals (-3.02%)" were weak.

While US markets were solid (S&P 500 +1.07%, NASDAQ100 +1.3%), futures (CME) were down 1.05%, suggesting adjustment. USD/JPY advanced to 151.23 yen (yen weakness). Volatility (Nikkei VI 30.06) remained elevated though flat.

🧩 Layer A: Market

🔹 Market Dynamics

• Nikkei 225: +0.27%, TOPIX: +0.03% ⇒ Domestic value stocks favored. High-beta stocks and semiconductor-related names saw profit-taking, while defensive sectors (telecommunications, services) were bought back.

• Nikkei VI: 30.06 (+0.07%) ⇒ Volatility levels remain high, with sustained hedging demand in options markets.

• SKEW: 151.3 (+2.5%) ⇒ Tail risk (sharp decline risk) premium rose slightly. Investor sentiment shifted from "risk-neutral → mild caution."

• Volume/Advancers-Decliners: 126 stocks up, 98 down—balanced. → Overall market is in a "sector rotation phase" with limited clear trend direction.

💬 Analysis

In the short term, US stock strength provided support, but technically, overheating remained. Profit-taking pressure was particularly notable in export-related stocks (machinery, metals). While the market welcomed the combination of "US rate slowdown × yen weakness," it's conscious of external factors (Middle East geopolitics, energy costs).

🧩 Layer B: Policy

🔹 Monetary Policy

• US 10-year yield: 3.986% (-0.021) ⇒ Dropped below 4%, clarifying the peak in US rates. Probability of December rate cut increasing according to Fed Watch.

• USD/JPY: 151.23 yen (+0.30%) ⇒ Yen weakness continues due to maintained US-Japan rate differential. Some speculation about currency intervention.

• BOJ: Maintains accommodative stance even after YCC flexibility ⇒ Consensus view that policy revision comes year-end or later.

💬 Analysis

Financial conditions remain accommodative (Easy bias). While Japan's interest rate suppression and continued yen weakness support corporate earnings (especially external demand), they constrain domestic sector recovery through reduced real purchasing power. Therefore, the policy layer has a neutral to slightly positive market impact.

🧩 Layer C: Trade (Supply Chain)

🔹 Indicators/Factors

• Machinery, non-ferrous metals, autos declined: Concerns about global demand slowdown. Particularly, export slowdown to China and ASEAN affecting some companies.

• Yen weakness (151 yen level): Improves export profitability. However, slowing US demand is a headwind.

• Shipping/logistics indices (SCFI, BDI): Some delays reported on Middle East routes. Rising crude oil prices pushing up freight costs.

💬 Analysis

Supply chain disruptions are limited, but geopolitical transportation risks are being reconsidered. Rising energy transportation costs are gradually impacting corporate margins. Stock price adjustments in export-related sectors (machinery, metals) appear to reflect this risk.

🧩 Layer D: Geopolitics

🔹 Current Major Factors

• Middle East situation: Re-emergence of Strait of Hormuz and Red Sea route risks → Some crude oil tanker navigation restrictions. Brent briefly exceeded $90.

• US-China tech friction: Observations of re-strengthened export restrictions on AI semiconductors and equipment → Background to selling of Tokyo Electron, Lasertec, etc.

• US election mode (2025 presidential primaries) → Rising uncertainty in trade and tariff policies.

💬 Analysis

The geopolitics risk layer contributes negatively in the short term. The decline in semiconductor equipment stocks (precision instruments) was particularly due to concerns about renewed US-China friction. Meanwhile, risk-hedging buying entered defense, telecommunications, and infrastructure-related stocks.

🔄 Comprehensive Score (Z-normalization basis)

➡ 4-Layer Composite Index (average) = +0.0σ (Neutral) → For the Nikkei average, "interest rate/policy support" and "geopolitical/external demand concerns" are in equilibrium.

Key Points to Watch (Local Projection basis)

[Monitoring factors for future outlook]

Summary: Cross-Layer Scenario

Conclusion (Investor Insights)

Short-term (1-2 weeks): Upside momentum continues in tandem with US stocks, but geopolitical risks rising. Medium-term (1-3 months): Solid foundation from policy support (yen weakness + accommodation), but watch for corrections in machinery and metals sectors.

• Recommended Strategy:

  • Overweight: Value/domestic demand (telecommunications, services, financials)

  • Risk management essential: External demand high-beta (machinery, metals)

  • Hold as hedge positions: Defense and energy stocks
