The Innovator U.S. Equity Buffer ETF (BJAN) aims to replicate the performance of the SPDR S&P 500 ETF Trust (SPY), offering investors exposure to the S&P 500. This fund protects against the first 9% of potential losses over a defined period, though it also limits upside gains with a predetermined maximum. Investors can hold this ETF long-term, as its features, including the cap and buffer, are reset at the conclusion of each outcome period, which happens approximately once a year.
