| Factors Affecting Performance [Text Block] | WHAT FACTORS INFLUENCED PERFORMANCE FOR THE PERIOD? For the Period, the Argent Mid Cap ETF achieved a market price return of 32.72% and a net asset value (NAV) return of 32.84%. These returns outperformed its benchmark, the Russell 3000 Index, by 514 basis points at market price and 526 basis points at NAV. The Fund’s outperformance was primarily driven by stock selection as intended by the investment process. Allocation slightly detracted from performance. At the sector level, the Industrials sector saw gains due to both stock selection and an overweight allocation. Stock selection in the Consumer Discretionary and Health Care sectors also contributed positively. Key stocks with company-specific catalysts that drove this outperformance included: • United Rentals (Industrials): The construction equipment rental provider benefited from resilient organic growth and strong margins despite concerns about a peak in commercial construction and a housing market slowdown. • TopBuild (Consumer Discretionary): The building materials supplier also showed resilience in organic growth and maintained strong margins, which investors rewarded. • Medpace (Health Care): The contract research organization outperformed its peers who were struggling with reduced bioprocessing spending and weakness in China. Conversely, the Technology sector was the primary drag on performance, largely due to the Fund not holding shares of Nvidia, a significant beneficiary of AI demand. |
