| Factors Affecting Performance [Text Block] | HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE? During the year ended December 31, 2025, the Fund returned 67.07%. The Fund outperformed its broad-based index, the S&P500, which returned 17.88%. The Fund also outperformed its more narrowly-based, secondary index which more closely reflects the types of securities in which it invests, the S&P SmallCap 600 Pure Value Index, which returned 8.83%. WHAT FACTORS INFLUENCED PERFORMANCE Holdings in the Materials sector in aggregate significantly contributed to Fund performance during the reporting period, with aggregate holdings in the Gold, Silver, & Precious Metals & Minerals industry being a large contribution to those returns. Fund holdings in the Energy sector also contributed to Fund performance during the reporting period. Fund holdings in the Real Estate and Consumer Staples sectors contributed the least or detracted from Fund performance. Compared to the S&P 500, the Fund’s outsized exposure to small cap stocks weighed on performance during the reporting period, as small cap stocks generally underperformed large cap stocks. Additionally, the Fund’s outsized exposure to value stocks weighed on performance, as value stocks generally underperformed growth stocks during the year ended December 31, 2025.
