| Factors Affecting Performance [Text Block] | What drove fund performance during the past 12 months? International small-cap stocks posted solid gains in the year ended October 31, 2024. Inflation decelerated almost universally across developed economies, clearing the path for central banks to start cutting interest rates. With employment and growth still quite resilient, the pace of monetary easing was gradual. Versus the S&P Global ex-U.S. Small Cap Index Net, the leading contributor to relative performance was stock selection in Japan. Shares of IHI Corporation soared as markets rewarded the industrial conglomerate's solid growth, driven by its civil aero engines and defense equipment segment. Our overweight position and stock choices in China also added value. On the negative side, the leading detractor from relative performance was stock selection in Italy. Amplifon was a major laggard. The retailer of hearing care solutions saw disappointing performance in European markets, particularly France, and faced some operational challenges in Spain. Our stock choices in the UK also weighed on performance. The fund invests in rapidly growing, small to medium-sized companies outside the U.S. with a focus on durable growth opportunities. We focus on companies that have a sound business model and management team, a prudent balance sheet, and a reasonable valuation and that are operating within an attractive industry structure. We continued to try and ensure a balanced portfolio. The recent past has been a tough environment for quality compounders so this was an area of focus, especially as we started to see signs that major external disruptions (COVID on/off, supply chain collapse/overstock, China weakness) were beginning to normalize. | ||
