Overview

Japan's stock market has recently been in turmoil again, with the Nikkei Average Index powerfully breaking through the 65,000-point barrier, reaching an intraday high of 65,018 yen. This milestone rally was not driven by a broad-based market surge, but rather by a strong pull from the technology sector centered on the artificial intelligence (AI) and semiconductor industry chains. Investor capital is accelerating its concentration into areas with technological barriers, such as chip manufacturing equipment, storage, and packaging materials, with market sentiment showing significant improvement.

Core Driver: AI Semiconductor Sector Leads the Rally

The rapid rise in the index is mainly due to the recovery in semiconductor industry prosperity driven by the surge in global AI computing power demand. Market focus is centered on several leading domestic Japanese companies with core competitiveness, which are seen as the "main attackers" of this trend.

Main beneficiaries include:

  • Advantest (6857): As the global leader in semiconductor test equipment, it directly benefits from the increased demand for mass production of high-end chips.
  • Kioxia Holdings (285A): An important producer of flash memory, benefiting from expectations of a reversal in the storage cycle.
  • Tokyo Electron (8035): A key supplier of lithography and thin-film deposition equipment, representing Japan's semiconductor equipment exports.
  • Ibiden (4062): A manufacturer of high-frequency multi-layer printed circuit boards, providing key foundational components for AI servers.
  • Fujikura (5803): Holds an important market share in high-speed transmission cables and semiconductor manufacturing materials.

"The center of the rise clearly points to AI and semiconductors; capital is grouping around core assets." — Market analysts point out that the performance expectations of these companies are highly linked to global AI capital expenditure.

Investment Strategy: Start with a Small Position, Gradually Build Up

In the face of the index's rapid rise, professional investors recommend adopting a cautious and flexible strategy. For retail investors who wish to participate in this rally but have limited risk tolerance, there is no need to rush into heavy positions chasing highs.

It is recommended to first make a trial position with a small amount of 100 shares. This "start small" strategy can both capture upside benefits and effectively control principal risk during volatile swings. After the market trend becomes clearer or a pullback confirms support, consider adding to the position based on market conditions.

Although the market is currently showing an upward trend, investors still need to pay attention to the Federal Reserve's monetary policy developments and the latest changes in the global semiconductor supply chain, maintaining rationality and avoiding blind leveraged operations.
