The Innovator International Developed Power Buffer ETF is designed to replicate the performance of the iShares MSCI EAFE ETF (EFA), with an upper limit on potential gains. Concurrently, it shields investors from the initial 15% of any losses over its defined outcome period. This exchange-traded fund can be held for an unlimited duration, as its cap and buffer features are re-established roughly once a year at the end of each outcome period.
