Core holdings as of recent data include Taiwan Semiconductor Manufacturing Co Ltd, SK Hynix Inc, Hon Hai Precision Industry Co Ltd, Tencent Holdings Ltd, and Fujikura Ltd, representing approximately 20.59% of the portfolio; sector allocations emphasize technology (22.84%), industrials (20.72%), and financial services (18.10%), while geographic exposure spans developed Asia (23.54%), Eurozone (23.06%), emerging Asia (10.90%), Japan (10.43%), and the United Kingdom (6.87%), with total net assets of $1.13 billion and a net expense ratio of 1.15%.

Recent portfolio adjustments as of September 2025 include increased exposure to information technology via new purchases of Hon Hai Precision and Samsung Electronics, trims to software holdings like Constellation Software and SAP amid earnings concerns, and an overweight to consumer discretionary with positions in Dollarama and MercadoLibre despite short-term pressures; the strategy reported a trailing 1-year turnover of 100.7% and continues to waive fees to limit operating expenses until April 30, 2026.
