|
| Davis Financial Fund | Foreign Country Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | 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] | Large-Capitalization Companies Risk. Companies with $10 billion or more in market capitalization are considered by the Adviser to be large-capitalization companies.

|
| Davis Financial Fund | Fees and Expenses Risk [Member] | |
| Prospectus [Line Items] | |

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.
|

| Prospectus [Line Items] | |
| Risk [Text Block] | Mid- and Small-Capitalization Companies Risk.
