Investors are optimistic about potential economic and market reforms in India, while tech-heavy Taiwan rode the wave of enthusiasm about AI spending. China has yet to fully recover from extended COVID lockdowns and declines in residential home prices have soured prospects for economic growth.

The U.S. economy and job growth started to decelerate while other developed economies were slowly catching up. U.S. real GDP grew slower than investors had anticipated. The weak growth was due to a decline in business inventories, a decline in government purchases, and a sharp rise in imports that led to negative net contribution from trade. The following is a summary of the top contributors and detractors that impacted the Fund's performance during the year relative to the Performance Index.
