| Factors Affecting Performance [Text Block] | How did the Fund perform? For the fiscal year ended September 30, 2024, the TETON Westwood Balanced Fund underperformed its primary benchmark, the S&P 500 Index. Equity markets in the U.S. were driven by large-cap growth companies especially those focused on artificial intelligence. As the year wore on, investors widened their focus to include small-cap and value stocks. Bond markets posted double-digit gains led by high yield and corporate debt, as interest rates fell in anticipation of a rate cut by the Federal Reserve. We increased our equity position to take advantage of the rally. We also shortened the duration of the fixed-income allocation, as interest rates have declined. |

| Factors Affecting Performance [Text Block] | How did the Fund perform? For the fiscal year ended September 30, 2024, the TETON Westwood Convertible Securities Fund underperformed its benchmarks, the S&P 500 and ICE BAML U.S. Convertibles Indices. The Fund was overweight balanced convertibles which performed well this year but could not keep up with the best performers in the index. Relative performance improved later as the market rotation from mega cap to small cap benefitted many balanced convertible issues. Top contributors this year included some semiconductor holdings as well as online education and space system providers. Top detractors were companies undertaking significant capital investment focused on clean energy and electric vehicles. |

| Factors Affecting Performance [Text Block] | How did the Fund perform? For the fiscal year ended September 30, 2024, the TETON Westwood Convertible Securities Fund underperformed its benchmarks, the S&P 500 and ICE BAML U.S. Convertibles Indices. The Fund was overweight balanced convertibles which performed well this year but could not keep up with the best performers in the index. Relative performance improved later as the market rotation from mega cap to small cap benefitted many balanced convertible issues. Top contributors this year included some semiconductor holdings as well as online education and space system providers. Top detractors were companies undertaking significant capital investment focused on clean energy and electric vehicles. |

The “Magnificent Seven” led the market through June, at which point the markets broadened and small-cap and value stocks gained ground. During the period, three of our top holdings were large banks, and Financials was the best performing sector. Energy stocks had a negative impact on total return, as two large companies declined and the sector as a whole trailed the benchmark. |

| Factors Affecting Performance [Text Block] | How did the Fund perform? During the fiscal year ended September 30, 2024, the TETON Westwood Equity Fund rode a market rally, but underperformed its primary benchmark, the S&P 500 Index. Equity markets in the U.S. posted strong returns, driven mostly by large-cap growth names. The “Magnificent Seven” led the market through June, at which point the markets broadened and small-cap and value stocks gained ground. During the period, three of our top holdings were large banks, and Financials was the best performing sector. Energy stocks had a negative impact on total return, as two large companies declined and the sector as a whole trailed the benchmark. |

The Fund’s underperformance is attributable to its exposure to micro-cap stocks, as the Fund seeks to invest in companies that have market capitalizations of $500 million or less at time of purchase. The environment for small caps was challenged relative to large capitalization companies given investor sensitivity to higher interest rates and concerns of an economic slowdown. |

| Factors Affecting Performance [Text Block] | How did the Fund perform? During the twelve months ended September 30, 2024, the TETON Westwood SmallCap Equity Fund underperformed the Russell 2000 Index. The primary detractors included value-oriented technology holdings, mixed returns for our healthcare names, and a drag from single stock that was acquired at a significant premium following the marking period. Our banks, trading at low valuations, drove strong gains into the advent of a rate-cutting cycle. Also, a data center related name powered our industrials. The Fund remains value-oriented in pursuit of opportunities, preferring companies with downside protection in the form of solid balance sheets or defensible business models. |
