The Aptus International Enhanced Yield ETF (IDUB) is an actively managed fund that employs a distinctive, dual investment approach. Its core strategy integrates exposure to global equities with equity-linked notes (ELNs). Primarily, the fund allocates its assets to an "Equity Strategy" by investing in a selection of other exchange-traded funds. These underlying ETFs, in turn, hold shares of companies located outside the United States, covering both established (developed) and rapidly growing (emerging) international markets. The remaining portion of its portfolio is dedicated to an "ELN Strategy," which involves using equity-linked notes (ELNs) to generate income. Notably, IDUB is classified as a non-diversified fund.
