GMAYCFT Vest U.S. Equity Moderate Buffer ETF - May

In short

CAUG No data

GMAY First Trust runs a buffer fund for every month of the calendar, and GMAY holds the May slot: a 15% cushion on SPY's price return over a one-year outcome period, paid for with a cap on the upside set when the period begins.

Stated mandate

CAUG No data

GMAY The Fund seeks returns corresponding to the price return of the State Street® SPDR® S&P 500® ETF Trust, subject to an upside cap and protection against the first 15% of losses during the stated outcome period.

Why people hold it

CAUG No data

  • GMAY The deal is spelled out in the fund's own documents: protection against the first 15% of losses on SPY's price return, plus a stated cap, across a defined one-year outcome period.ftportfolios.com
  • May is just one rung. GJAN through GDEC run the same 15% structure on a rolling monthly schedule, so start dates can be staggered instead of hostage to one entry point.
  • The reference asset is the SPDR S&P 500 ETF Trust itself. Plain large-cap US equity price return, no custom index or factor tilt to decode.
  • One of the easier funds in its buffer peer group to get in and out of, with a mid-sized asset base standing behind it.

Worth knowing

CAUG No data

  • GMAY At 0.85%, it sits above the 0.79% median for its buffer cohort. Downside protection is a purchased feature, and the sticker shows it.
  • The cap works both ways: big SPY years get trimmed. And the 15% buffer is measured from the start of the outcome period to its end, not day by day in between.
  • Not an income vehicle. The options package is built to shape the payoff, not to pay out along the way.
