Because Class R6 shares had not commenced operations as of the date of this Prospectus, the following chart and table show the Fund’s Institutional Class share 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 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).Class R6 shares and Institutional Class shares of the Fund would have substantially similar performance because they invest in the same portfolio of securities. However, the performance of Class R6 shares would be higher than Institutional Class shares to the extent Class R6 shares pay lower expenses than Institutional Class shares. 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.
