| Performance Narrative [Text Block] | The following chart and table provide some indication of the risks of investing in the Fund by showing the Fund’s Institutional Class shares calendar year performance from year to year and average annual returns for the one, five and ten year or, if shorter, since inception periods, as applicable, for the Fund’s Institutional Class and Class A shares compared to those of a regulatorily required broad-based securities market index (Bloomberg U.S. Aggregate Bond Index) and an additional index (Bloomberg 1-3 Month U.S. Treasury Bill Index).On November 30, 2018, Guggenheim Strategy Fund I (the “Predecessor Fund”), which also was an investment company registered under the Investment Company Act of 1940, reorganized with and into the Fund, which has adopted the Predecessor Fund’s performance history. Accordingly, the performance information shown below prior to that date reflects the performance of the Predecessor Fund and not that of the Fund. However, the Predecessor Fund’s policies, guidelines and investment objective were the same as those of the Fund’s in all material respects. Because Class P shares of the Fund are not currently offered for sale and do not have a full calendar year of performance history as of the date of this Prospectus, no performance information for Class P shares is shown.The returns shown below for the Predecessor Fund have been restated to reflect the fees and expenses applicable to the Institutional Class shares of the Fund, exclusive of any applicable expense limitation agreement. As with all mutual funds, past performance (before and after taxes), including the past performance of the Predecessor Fund, is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available on the Fund’s website at www.guggenheiminvestments.com or by calling 800.820.0888. |
