| Factors Affecting Performance [Text Block] | WHAT FACTORS INFLUENCED PERFORMANCE FOR THE PERIOD? The Fund returned 10.20% (NAV) for the Period, vs 16.75% for Solactive GBS Global Markets All Cap Index. The Fund invests in a portfolio of global equities split equally between U.S. and non-U.S. equities. The Fund’s performance was impacted by the Fund’s higher allocation to non-U.S. securities, as the U.S. markets performed better than international markets, mainly led by the information technology sector riding the artificial intelligence euphoria. During the Period, the Fund had very little exposure to the technology sector compared to the broader market. This, coupled with the Fund’s higher exposure to the defensive sectors like the health care and consumer staples sectors, led to underperformance. On an absolute basis, the Fund’s performance has been in line with its philosophy of investing in companies that are stable and provide steady and growing dividends. To that extent, the Fund’s exposure to the industrial sector, which is the Fund’s second largest sector after health care, coupled with stock selection was the largest contributor. The Fund’s financial sector exposure added to the Fund’s performance as both U.S. and non-U.S. financials performed well. After decades of low interest rates, banks globally are seeing higher interest incomes and margins on their core lending businesses, leading to robust returns on equity and strong capital positions. We continue to look for strong and steady dividend payers trading at reasonable valuations across all sectors and lack of exposure to mega-cap tech stocks that barely pay dividends and trade at premium valuations detracted performance. |
