The Innovator International Developed Power Buffer ETF (IAPR) is designed to mirror the performance of the iShares MSCI EAFE ETF (EFA). It offers a degree of downside protection by absorbing the initial 15% of any losses sustained over a specified "outcome period." However, this protection comes with a trade-off, as potential gains are limited by a pre-set maximum. Investors can hold this ETF perpetually, as its cap and buffer terms are renewed and redefined at the close of each outcome period, which typically occurs on an annual basis.
