The Innovator U.S. Equity Accelerated 9 Buffer ETF is designed to offer twice the upside performance of the SPDR S&P 500 ETF Trust (SPY), limited by a predefined cap, while generally maintaining proportionate (1x) exposure to SPY's downside. Over its one-year outcome period, this fund shields investors from the initial 9% of SPY's losses. While it can be held long-term, the ETF's specific cap and buffer features reset approximately once a year.
