Japan Portfolio Weekly Review: Semiconductor Focus Drives Mixed Returns

Review Date: July 6, 2026

Portfolio Overview

The Japan Portfolio is concentrated in four holdings, all listed on the Tokyo Stock Exchange (TSE Prime Market). The portfolio emphasizes Japan’s strength in semiconductor equipment and advanced manufacturing. Current positions include TOWA Corporation, The Japan Steel Works, Disco Corporation, and SCREEN Holdings.

Performance Summary

  • TOWA Corporation (TOWCF): +8.62% since pick (June 7, 2026). Benefiting from strong demand for semiconductor packaging equipment.
  • The Japan Steel Works (JPSWY): +5.76% since pick (June 15, 2026). Gains driven by industrial machinery and energy sector demand.
  • Disco Corporation (DSCSY): -4.52% since pick (June 22, 2026). Pullback amid broader semiconductor sector volatility; fundamentals remain solid.
  • SCREEN Holdings (DINRF): 0.00% since pick (July 1, 2026). New position, no material price change yet.

Risk Concentration

The portfolio is heavily weighted toward semiconductor equipment and related manufacturing. This concentration offers upside from Japan’s dominant position in the global chip supply chain but also exposes the portfolio to cyclical semiconductor downturns. No single position exceeds 30% of the portfolio, but thematic overlap is high.

What to Watch

  • Semiconductor capital expenditure trends, especially from major chipmakers like TSMC and Samsung.
  • Japan’s government subsidies for domestic chip production.
  • Currency fluctuations (JPY/USD) impacting export competitiveness.
  • Earnings reports from Disco and SCREEN in the coming weeks.

Position Closure Decisions

No positions are recommended for closure at this time. All holdings are within their minimum 180-day holding period and remain aligned with the portfolio’s Japan-focused, semiconductor-oriented thesis. Temporary price declines (e.g., Disco) do not warrant exit.

Outlook

The Japan Portfolio remains well-positioned to benefit from structural demand for advanced semiconductor manufacturing equipment. We maintain a constructive view on the region and the selected holdings.
