The Innovator Emerging Markets Power Buffer ETF is designed to mirror the investment performance of the iShares MSCI EM ETF (EEM). It aims to provide investors with a degree of downside protection by absorbing the first 15% of any losses incurred over a specific 'outcome period'. However, its potential for gains is capped at a pre-established maximum return. While suitable for long-term holding, the fund's protective buffer and return cap are re-evaluated and reset at the conclusion of each outcome period, which typically spans approximately one year.
