The FT Vest U.S. Equity Buffer ETF - December (FDEC) is designed to offer investors returns that largely mirror the price movements of the SPDR S&P 500 ETF Trust (its underlying benchmark). However, this aim comes with specific parameters: it limits potential gains to a predetermined maximum of 14.75% while also providing protection against the initial 10% of losses experienced by the underlying ETF. Both the upside cap and downside buffer are calculated before accounting for any fees and expenses. This investment strategy is applicable over a defined period, spanning from December 22, 2025, to December 18, 2026.
