ABHY tracks an index that invests in US-listed high yield ETFs while applying a downside protection. The risk-managed fund employs a tactical strategy that toggles between high yield and US Treasury ETFs. This tactical switch is determined by a daily buy-sell signal. Full exposure is allocated to high yield ETFs when a buy signal is triggered, while 80% is allocated to US Treasurys when it triggers otherwise. Underlying ETFs must meet certain expense ratio and AUM requirements to be considered. In addition, both must have an investment process that excludes factors, hedges and long/short strategies. The underlying ETFs are weighted based on their respective expenses and AUM, whether its junk bonds or Treasurys. The index is rebalanced quarterly and reconstituted annually. DFHYs investors should anticipate frequent trading. Prior to Nov. 29, 2021, the fund was named TrimTabs Donoghue Forlines Tactical High Yield and tracked the TrimTabs Donoghue Forlines Tactical High Yield Index. Prior to Nov. 13, 2024 the fund name was Donoghue Forlines Tactical High Yield ETF and traded under the ticker DFHY.
