Factors Affecting Performance [Text Block]
WHAT FACTORS INFLUENCED PERFORMANCE FOR THE PERIOD?
For the reporting period ended June 30, 2026, the Fund generated a positive absolute return as markets appreciated, outperforming its benchmark, the Solactive GBS United States Large & Mid Cap Index. During the Period, U.S. equity market leadership broadened beyond a narrow group of large-cap growth stocks, particularly those trading at elevated valuations. The Fund benefited from this shift, as its fundamentals-driven constituent selection process resulted in lower exposure to many of these highly valued companies.
Outperformance was driven primarily by the Fund’s fundamentals-driven selection methodology, particularly within the Technology sector. Additional contributions came from several other sectors, including Communications, Consumer Cyclical, Healthcare, and Financials. As investors became more selective toward companies with elevated valuations, market performance broadened, benefiting companies with stronger underlying fundamentals and more reasonable valuations. The Fund's methodology was well positioned for this shift in market leadership. Modest underperformance arose from holdings within the Industrials, Consumer Non-Cyclical, and Utilities sectors.

Factors Affecting Performance [Text Block]  
WHAT FACTORS INFLUENCED PERFORMANCE FOR THE PERIOD?
For the 12-month period ended June 30, 2026, the Fund generated a positive absolute return as markets appreciated, outperforming its benchmark, the Solactive GBS United States All Cap Index. During the reporting period, U.S. equity market leadership broadened beyond a narrow group of large-cap growth stocks, resulting in stronger performance from value-oriented and smaller-cap companies. This shift benefited the NIXT strategy, which systematically targets companies recently deleted from traditional large- and mid-cap indices. These deleted companies are typically smaller-cap value stocks, a segment that outperformed over the period.

The Fund's outperformance was driven primarily by its exposure to smaller-cap value stocks, which benefited as investors broadened their focus beyond the narrow group of mega-cap technology companies that had led the market in prior years. As investor interest expanded to a wider range of companies, many smaller-cap stocks, particularly those trading at attractive valuations following extended periods of underperformance, experienced strong gains. Relative detractors to performance arose from the Fund's holdings within the Industrials sector, as well as a collection of large technology names held within the benchmark and excluded from the Fund.
