| Factors Affecting Performance [Text Block] | How did the Fund perform last year? For the fiscal year the Fund returned 3.17%, underperforming the Russell Microcap Index. Top contributors to performance The Fund’s investment universe focuses on the smallest stocks within the US stock market (the CRSP 10 universe). The Fund’s performance relative to the CRSP 10 universe was positive. Top detractors to performance The Fund’s focus on the CRSP 10 universe hurt relative results, as CRSP 10 stocks underperformed the Russell Microcap Index. On average, the Fund held about 82% of its assets in the CRSP 10 universe, versus roughly 11% for the benchmark. The Fund’s sidestepping strategies, which eliminate exposure to stocks with a high probability of a steep price decline, major financial distress or bankruptcy, also hurt performance relative to the CRSP 10 universe. |
