| Factors Affecting Performance [Text Block] | How did the Fund perform during the reporting period? During the fiscal year ended June 30, 2024, our most reliable equity market valuation measures reached the steepest extreme in U.S. financial history, exceeding levels observed at the 1929 and 2000 peaks. Narrow speculation among a handful of large-cap technology stocks, coupled with growing divergence across a broader range of market internals, continued to suggest underlying risk-aversion among investors. Weakness in leading economic measures, particularly new orders, backlogs, and a shift in labor composition from full-time to part-time employment, remained at levels consistent with emerging risk of recession. Short and intermediate-term market action also became increasingly overextended during this period. Amid these conditions, the Fund maintained a defensively hedged investment stance, consistent with its long-term, full-cycle, risk-managed discipline. The Adviser continues to view the 2022-2024 period as the extended peak of the third great speculative bubble in U.S. history. Given its intentionally defensive stance, the Fund’s performance during the fiscal year did not materially deviate from what could be expected approaching such extremes. The -8.72% total return of the Fund was attributable partly to the difference in performance between the stocks held by the Fund and the indices used to hedge, and partly to the loss of time value on defensive index put option positions. The Fund’s investment stance is expected to change in response to shifts in observable market conditions. The following equity holdings achieved gains in excess of $2 million during the fiscal year ended June 30, 2024: Super Micro Computer, Meta Platforms, Sweetgreen, AppLovin, Alphabet, NetApp, Hibbett Sports, Amazon and ACM Research. Equity holdings with portfolio losses in excess of $2 million during this period were Canadian Solar, SolarEdge Technologies, United Natural Foods and Array Tech. | |

The Adviser continues to view the 2022-2024 period as the extended peak of the third great speculative bubble in U.S. history. Amid these conditions, the Fund maintained a largely hedged investment stance in equities, consistent with its long-term, full-cycle, risk-managed discipline. Short-term Treasury bill yields remained above 5% during the fiscal year, with lower yields prevailing on longer-term Treasury securities. The Fund held positions in bonds across the maturity spectrum, with an average duration of 2-4 years, and approximately 40-50% of bond holdings in Treasury inflation-protected securities. The 1.43% total return of the Fund reflected positive returns in the Fund’s fixed income holdings, while the hedged equity segment of the portfolio reduced overall performance due to a difference in performance between the stocks held by the Fund and the indices used to hedge. The Fund’s investment stance is expected to change in response to shifts in observable market conditions.

| Factors Affecting Performance [Text Block] | How did the Fund perform during the reporting period? During the fiscal year ended June 30, 2024, short-term Treasury bill yields remained above 5%, with lower yields prevailing on longer-term Treasury securities. The Fund held positions in Treasury securities across the maturity spectrum, with an average duration of 2-4 years, and approximately 40-60% of bond holdings in Treasury inflation-protected securities. The Fund held varying exposure in the stocks of companies in the precious metals industry, ranging between 5-15% of net assets. Historically, the strongest performance of precious metals shares has typically emerged either during periods of falling interest rates, or amid quite rapid and accelerating inflation. While inflationary pressures abated during the year, a combination of declining interest rates and emerging economic weakness continued to support exposure to this sector. The Fund held relatively smaller exposures in shares of companies in the utility and energy industries during the year. The Fund’s investment stance is expected to change in response to shifts in observable market conditions. The 6.73% total return of the Fund during the fiscal year benefited from both the fixed income and equity holdings in the portfolio. The Fund has outperformed its benchmark, the Bloomberg U.S. Aggregate Total Return Index, for the past 1, 3, 5, 7, and 10 years, as well as since the Fund’s inception on September 12, 2002. The following holdings achieved portfolio gains in excess of $250,000: Agnico Eagle Mines, NRG Energy, Anglogold Ashanti, Barrick Gold, Kinross Gold, SM Energy and a two U.S. Treasury Notes maturing in 2024 and 2025. Portfolio holdings with a loss in excess of $250,000 during this period were B2Gold and UGI. | |
