Portfolio Turnover [Text Block]

Portfolio Turnover: The Energy Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when the Energy Fund’s shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Energy Fund’s performance. During the most recent fiscal year ended November 30, 2025, the Fund’s portfolio turnover rate was 6% of the average value of its portfolio.
