| Performance Narrative [Text Block] | The bar chart and table set out below show The Fairholme Fund’s historical performance and provide some indication of the risks of investing in The Fairholme Fund by showing changes in The Fairholme Fund’s performance from year to year and by showing how The Fairholme Fund’s average annual total returns for the 1‑, 5‑, and 10‑year periods and since inception compare to the performance of the S&P 500 Index. The S&P 500 Index is a widely recognized, unmanaged index of 500 of the largest companies in the United States as measured by market capitalization. The S&P 500 Index assumes reinvestment of all dividends and distributions. Because indices cannot be invested in directly, these index returns do not reflect a deduction for fees, expenses or taxes. The Fairholme Fund’s past performance (before and after taxes) is not necessarily an indication of how The Fairholme Fund will perform in the future.
