ALDB is a portfolio of defined outcome buffer ETFs. It utilizes a laddered approach, gaining US large-cap equity market exposure while limiting downside risk. It consists of 4 equity deep buffer funds that seek to match SPY's share price gains to a predetermined upside cap over a 12-month period while aiming to protect against losses between -4% and -34% of index losses. The adviser believes this time ladder approach will help reduce the risk of failing to benefit from the buffer of a single underlying ETF and allow the fund to continue to profit from SPY upside while providing downside protection at any given time. Each underlying ETF will reset its cap and refresh its buffer annually. Information on ABUF's exposure to the underlying ETFs is provided daily on the issuer's website. Portfolio rebalancing to equal weights is also done annually. ALDB will buffer the first 4% of SPY losses.
