| Portfolio Turnover [Text Block] | oef_PortfolioTurnoverTextBlock | The 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 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 10% of the average value of its portfolio.

| Strategy [Heading] | oef_StrategyHeading | Principal Investment Strategies of the Fund | |||||||||||||
| Strategy Narrative [Text Block] | oef_StrategyNarrativeTextBlock | Davis Selected Advisers, L.P. (“Davis Advisors” or the “Adviser”), the Fund’s investment adviser, uses the Davis Investment Discipline to invest, under normal market conditions, at least 80% of the Fund’s net assets, plus any borrowing for investment purposes, in securities issued by companies principally engaged in the financial services sector. The Fund invests principally in common stocks (including indirect holdings of common stock through Depositary Receipts (as defined below)). The Fund may invest in large, medium or small companies without regard to market capitalization and may invest in issuers in foreign countries, including countries with developed or emerging markets.
A company is principally engaged in financial services if it owns financial services-related
assets that constitute at least 50% of the value of all of its assets, or if it derives at least 50% of its revenues from
providing financial services. Companies are classified by GICS based on their principal business activity. Revenue is a key factor in determining a firm’s principal business activity. Financial services companies include those with their principal business
activity in one of the following areas: banks, financial services, consumer finance, capital markets, insurance, and mortgage REITs.
Davis Investment Discipline. Davis Advisors manages equity funds using the Davis Investment Discipline. Davis
Advisors conducts extensive research to try to identify businesses that possess characteristics
that Davis Advisors believes foster the creation of long-term value, such as proven management, a durable franchise and business
model, and sustainable competitive advantages. Davis Advisors aims to invest in such businesses when they are trading
at discounts to their intrinsic worth. Davis Advisors emphasizes individual stock selection and believes that the ability to evaluate
management is critical. Davis Advisors routinely visits managers at their places of business in order to gain insight into
the relative value of different businesses. Such research, however rigorous, involves predictions and forecasts that are inherently
uncertain. After determining which companies Davis Advisors believes the Fund should own, Davis Advisors then turns its
analysis to determining the intrinsic value of those companies’ equity securities. Davis Advisors seeks companies whose equity securities can be purchased at a discount from Davis Advisors’ estimate of the company’s intrinsic value based upon fundamental analysis of cash flows, assets and liabilities, and other criteria that Davis Advisors deems to be material on a company-by-company basis. Davis Advisors’ goal is to invest in companies for the long term (ideally, five years or longer, although
this goal may not be met). Davis Advisors considers selling a company’s equity securities if the securities’ market price exceeds Davis Advisors’ estimates of intrinsic value, if the ratio of the risks and rewards of continuing to own the company’s equity securities is no longer attractive, to raise cash to purchase a more attractive investment opportunity, to satisfy net
redemptions, or for other purposes.

| Performance Narrative [Text Block] | oef_PerformanceNarrativeTextBlock | The bar chart below provides some indication of the risks of investing in the Fund by showing how the Fund’s investment results have varied from year to year. The following table shows how the Fund’s average annual total returns, for the periods indicated, compare with the S&P 500 Index, a broad-based securities market index, and the S&P 500 Financials Index. The S&P 500 Financials Index is a measure of the performance of the companies in the financial sector as a subset of the S&P 500 Index. The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated information on the Fund’s results can be obtained by visiting www.davisfunds.com or by calling 1-800-279-0279.
After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown, and after-tax returns shown are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. After-tax returns are shown only for Class A shares; after-tax returns for other share classes will vary.

| Risk [Text Block] | oef_RiskTextBlock | Foreign Country Risk. Securities of foreign companies (including Depositary Receipts) may be subject to greater risk, as foreign economies may not be as strong or diversified, foreign political systems may not be as stable and foreign financial reporting standards may not be as rigorous as they are in the United States. There may also be less information publicly
available regarding the non-U.S. issuers and their securities. These securities may be less liquid (and, in some cases, may be illiquid) and could be harder to value than more liquid securities.

| Risk [Text Block] | oef_RiskTextBlock | Depositary Receipts Risk. Depositary Receipts, consisting of American Depositary Receipts, European Depositary Receipts, and Global Depositary Receipts, are certificates evidencing ownership of shares of a foreign issuer. Depositary Receipts are subject to many of the risks associated with investing directly in foreign securities. Depositary Receipts may trade at a discount, or a premium, to the underlying security and may be less liquid than the underlying securities listed on an exchange.

| Risk [Text Block] | oef_RiskTextBlock | Fees and Expenses Risk. The Fund may not earn enough through income and capital appreciation to offset the operating expenses of the Fund. All mutual funds incur operating fees and expenses. Fees and expenses reduce the return that a shareholder may earn by investing in a fund, even when a fund has favorable performance. A low-return environment, or a bear market, increases the risk that a shareholder may lose money.

The change in value of a foreign currency against the U.S. dollar will result in a change in the U.S. dollar value of securities denominated in that foreign currency. For example, when the Fund holds a security that is denominated in a foreign currency, a decline of that foreign currency against the U.S. dollar would generally cause the value of the Fund’s shares to decline.

Securities of issuers in emerging and developing markets may offer special investment opportunities, but present risks relating to political, economic, or regulatory conditions not found in more mature markets, such as government controls on foreign investments, government restrictions on the transfer of securities, and less developed trading markets, exchanges, reporting standards, and legal and accounting systems. These securities may be more volatile and less liquid, which may also make them more difficult to value than securities in countries with developed economies.

Companies with less than $10 billion in market capitalization are considered by the Adviser to be mid- or small-capitalization companies. Mid- and small-capitalization companies typically have more limited product lines, markets, and financial resources than larger companies and their securities may trade less frequently and in more limited volume than those of larger, more mature companies.
