The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 11.64% of the average value of its portfolio.

The following example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% annual return each year and that the Fund’s operating expenses remain the same each year. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy [Heading] rr_StrategyHeading The Principal Investment Strategy of the Fund
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Value Fund invests primarily in the common stocks of small capitalization companies ($2.5 billion or less at the time of purchase) that the Paradigm Funds Advisor LLC (the “Advisor”) believes have the potential for capital appreciation. The Value Fund primarily invests in companies that exhibit attractive valuations on several metrics, such as price to earnings, price to cash flow, price to book and price to revenue. The Fund may be overweight in certain sectors at various times. Securities are sold when they have realized their anticipated value or if new investment opportunities with higher expected returns are acquired. The Fund may continue to hold securities of companies whose capitalization has, since the time of purchase, grown to exceed $2.5 billion.
Risk [Heading] rr_RiskHeading The Principal Risks of Investing in the Fund
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Risks of Small Capitalization Companies

 

The Fund invests in the stocks of small capitalization companies, which may subject the Fund to additional risks. The earnings and prospects of these companies are generally more volatile than larger companies. Small capitalization companies may experience higher failure rates than do larger companies. The trading volume of securities of small capitalization companies is normally less than that of larger companies and, therefore, may disproportionately affect their market price, tending to make them fall more in response to selling pressure than is the case with larger companies.

 

Risks in General

 

Domestic economic growth and market conditions, interest rate levels, and political events are among the factors affecting the securities markets in which the Fund invests. There is the risk that these and other factors may adversely affect the Fund’s performance. You could lose money by investing in the Fund.

 

Additionally, unexpected local, regional or global events, such as war; acts of terrorism; financial, political or social disruptions; natural, environmental or man-made disasters; the spread of infectious illnesses or other public health issues (such as COVID-19); and recessions and depressions could have a significant impact on the Fund and its investments and may impair market liquidity. Such events can cause investor fear, which can adversely affect the economies of nations, regions and the market in general, in ways that cannot necessarily be foreseen.

 

Risks of Investing in Common Stocks

 

Overall stock market risks may affect the value of the Fund. Factors such as domestic economic growth and market conditions, interest rate levels, and political events affect the securities markets. When the value of the Fund’s investments goes down, your investment in the Fund decreases in value and you could lose money.

 

Value Investing Risk

 

Value investing attempts to identify companies selling at a discount to their intrinsic value. Value investing is subject to the risk that a company’s intrinsic value may never be fully realized by the market or that a company judged by the advisor to be undervalued may actually be appropriately priced.

 

Sector Risk

 

Sector risk is the possibility that all stocks within the same group of industries will decline in price due to sector-specific market or economic developments. The Fund may be overweight in certain sectors at various times.

 

Investment Management Risk

 

The Advisor’s strategy may fail to produce the intended results.

Strategy [Heading] rr_StrategyHeading The Principal Investment Strategy of the Fund
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

Under normal circumstances, the Micro-Cap Fund invests at least 80% of its net assets in the common stocks of U.S. micro-cap companies. The Fund generally considers a company to be a micro-cap company if, at the time of purchase, its market capitalization is within the range of capitalizations of companies in the Russell Microcap® Index as of the most recent reconstitution date. As of March 31, 2021, the range of market capitalizations for the Russell Microcap® Index was $19 million to $13.239 billion. The capitalizations of companies within the Russell Microcap® Index may increase or decrease due to market conditions. The Fund may be overweight in certain sectors at various times. Stocks are sold when they have realized the value anticipated by the Advisor or if new investment opportunities with higher expected returns are acquired. The Fund may continue to hold stocks of companies whose capitalization has, since the time of purchase, grown to exceed the capitalization limits. Additional purchases of a company’s stock will not qualify, however, as a micro-cap stock, unless at the time of purchase, the company is able to satisfy the definition of a micro-cap. The Advisor primarily searches for companies within the market capitalization range of the Russell Microcap® Index that exhibit attractive valuations and solid growth prospects.
Risk [Heading] rr_RiskHeading The Principal Risks of Investing in the Fund
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Risks of Micro Capitalization Companies

 

The prices of micro-cap stocks are generally more volatile and their markets are less liquid relative to larger-cap securities. Therefore, the Fund may involve considerably more risk of loss and its returns may differ significantly from funds investing in larger-cap companies or other asset classes.

 

Risks of Small and Mid Capitalization Companies

 

The Fund may also invest up to 20% of its net assets in the common stocks of small and mid capitalization companies, which may subject the Fund to additional risks. The earnings and prospects of these companies are generally more volatile than larger companies. Small and mid capitalization companies may experience higher failure rates than do larger companies. The trading volume of stocks of small and mid capitalization companies is normally less than that of larger companies and, therefore, may disproportionately affect their market price, tending to make them fall more in response to selling pressure than is the case with larger companies.

 

Risks in General

 

Domestic economic growth and market conditions, interest rate levels, and political events are among the factors affecting the securities markets in which the Fund invests. There is the risk that these and other factors may adversely affect the Fund’s performance. You could lose money by investing in the Fund.

 

Additionally, unexpected local, regional or global events, such as war; acts of terrorism; financial, political or social disruptions; natural, environmental or man-made disasters; the spread of infectious illnesses or other public health issues (such as COVID-19); and recessions and depressions could have a significant impact on the Fund and its investments and may impair market liquidity. Such events can cause investor fear, which can adversely affect the economies of nations, regions and the market in general, in ways that cannot necessarily be foreseen.

 

Risks of Investing in Common Stocks

 

Overall stock market risks may affect the value of the Fund. Factors such as domestic economic growth and market conditions, interest rate levels, and political events affect the securities markets. When the value of the Fund’s investments goes down, your investment in the Fund decreases in value and you could lose money.

 

Value Investing Risk

 

Value investing attempts to identify companies selling at a discount to their intrinsic value. Value investing is subject to the risk that a company’s intrinsic value may never be fully realized by the market or that a company judged by the Advisor to be undervalued may actually be appropriately priced.

 

Growth Risk

 

Growth companies are those that the Advisor believes will have revenue and earnings that grow faster than the economy as a whole, offering above-average prospects for capital appreciation and little or no emphasis on dividend income. If the Advisor’s perceptions of a company’s growth potential are wrong, the securities purchased may not perform as expected, reducing the Fund’s return.

 

Portfolio Turnover Risk

 

A higher portfolio turnover may result in higher transactional and brokerage costs.

 

Sector Risk

 

Sector risk is the possibility that all stocks within the same group of industries will decline in price due to sector-specific market or economic developments. The Fund may be overweight in certain sectors at various times.

 

Investment Management Risk

 

The Advisor’s strategy may fail to produce the intended results.
