The Innovator Defined Wealth Shield ETF is engineered to replicate the gains of the SPDR S&P 500 ETF Trust (SPY), up to a specified maximum, while also providing a degree of safeguard against market downturns. It aims to absorb the first 20% of losses for investors over each three-month outcome period. This ETF is suitable for long-term holding, as its protective mechanisms reset quarterly after every outcome period.
