In short

CTAU No data

XDEC Most buffered funds trade upside away for protection. This December-dated First Trust fund goes after both: roughly twice the price gain of the SPDR S&P 500 ETF Trust up to a yearly cap, with the first 15% of losses absorbed.

Stated mandate

CTAU No data

XDEC The Fund seeks approximately twice the positive price return of the State Street® SPDR® S&P 500® ETF Trust, subject to a 10.06% upside cap and protection against the first 15% of losses during the stated outcome period.

Why people hold it

CTAU No data

  • XDEC Accelerated and buffered in one wrapper: it aims for about 2x the reference ETF's positive price return up to a cap, while absorbing the first 15% of a decline over the outcome period.
  • The reference is the SPDR S&P 500 ETF Trust itself, not a custom index built for the product, so the exposure being doubled is plain US large-cap.
  • One rung of a dated ladder. Siblings like XMAR, XJUN and XNOV run the same structure on different reset months, so entry isn't pinned to a single December date.
  • Live since 2021, which puts several full December-to-December outcome periods behind the strategy rather than a single test run.

Worth knowing

CTAU No data

  • XDEC At 0.85% a year it runs above accelerated peers such as XTAP and XDSQ at 0.79%. Layered options structures carry a higher price tag than plain beta.
  • The cap and buffer are engineered for a full outcome period, December to December, and the cap is reset at each new period. Buy mid-period and your own cap and remaining buffer differ from the headline terms.
  • Thinly traded next to mainstream index funds, so limit orders earn their keep. The design targets price return, not an income stream.
