| Factors Affecting Performance [Text Block] | What drove fund performance during the past 12 months? Japanese stocks posted solid gains in the year ended October 31, 2024. For much of the period, yen weakness boosted the profit outlooks for Japan’s export-oriented companies. The Bank of Japan raised interest rates twice, in March and July, but there was uncertainty about the pace of further monetary policy normalization given market volatility, global economic developments, and domestic political instability. Versus the TOPIX Index Net, the leading contributor to relative performance was stock selection in the machinery sector. Shares of IHI Corporation soared as markets rewarded the industrial conglomerate's solid growth, driven by its civil aero engines and defense equipment segment. Stock choices in commercial and wholesale trade also added value. On the negative side, the leading detractor from relative performance was the information technology and services sector due to stock selection and an underweight position. SHIFT was a major laggard. The provider of software testing services struggled amid a slowdown in demand and the lower utilization of consultants and engineers. Stock choices in energy resources also weighed on performance. The fund invests in Japanese companies across the market capitalization spectrum in a wide range of sectors, with a focus on opportunities where there is potential upside relative to the risks priced in the market (asymmetric risk-reward). We continued to closely manage the fund’s sector allocations and style exposures. With sector and style more neutralized relative to the benchmark, our focus was on stock selection, guided by our belief that improving governance will drive shareholder returns for many Japanese businesses. | ||
