KAPRCInnovator U.S. Small Cap Power Buffer ETF - April

SMAYDFT Vest U.S. Small Cap Moderate Buffer ETF - May

In short

KAPR Small caps are the bumpiest ride in US equities. KAPR straps a cushion to them: it tracks the Russell 2000 ETF across an April-to-March outcome period, absorbing the first 15% of losses in exchange for a ceiling on the upside.

SMAY Small caps with a seatbelt. SMAY absorbs the first 15% of a price decline in the Russell 2000 ETF over each one-year outcome period, trading that cushion for a ceiling on the upside. The clock resets every May.

Stated mandate

KAPR The fund seeks to follow the return of IWM up to a predetermined cap while protecting investors from the first 15% of losses during the outcome period, before fees and expenses.

SMAY The Fund seeks price-return participation in the iShares Russell 2000 ETF up to a 19.15% cap, while protecting the first 15% of losses during the May 18, 2026–May 21, 2027 outcome period.

Why people hold it

  • KAPR The buffer is the whole point: over each outcome period the fund aims to absorb the first 15% of the Russell 2000 ETF's decline, before fees and expenses.innovatoretfs.com
  • Costs 0.79% a year, level with Innovator's other small-cap buffer months and below the 0.90% charged by FT Vest's small-cap buffer funds (SMAY, SNOV).
  • April is your anchor: the period runs April 1 to March 31 with a fresh cap each spring, and sibling funds on other months (KJAN, KJUL, KOCT) let you stagger start dates.
  • Running since 2020 inside a plain 1940 Act ETF wrapper holding options, not a bank-issued note, so the payoff shape doesn't ride on one issuer's credit.innovatoretfs.com
  • SMAY The 15% buffer is written into the fund's design, not a target: over a full outcome period it takes the first 15% of a price drop in the iShares Russell 2000 ETF before you feel it.
  • Defined-outcome mechanics point at small caps, a corner of the buffer market where the field is thin and the reference is a single, widely held Russell 2000 fund.
  • The May start date lets you stagger entry across the calendar alongside other dated small-cap buffer funds (KJAN, KAPR, KJUL, KOCT) instead of betting on one reset month.
  • What's inside matches what's on the label: options tied to one reference fund, no drift, no side bets.

Worth knowing

  • KAPR Thinly traded next to the heavyweights of the buffer world, so spreads deserve a look, and the stated buffer and cap apply to holders who own it start to finish of a period.innovatoretfs.com
  • Upside stops at the cap struck each April, and the 15% cushion is measured before the 0.79% fee. Buy mid-period and you inherit whatever cap and remaining buffer exist that day.innovatoretfs.com
  • Options do the work instead of shares, so Russell 2000 dividends don't flow through and the fund has not been making regular distributions.innovatoretfs.com
  • SMAY The buffer and the cap belong to the full outcome period. Buy in the middle and you get whatever cushion and headroom are left, not the stated 15%.
  • At 0.90% a year, it sits above the 0.79% charged by the Innovator small-cap buffer funds running the same playbook.
  • It trades lightly, so spreads at the point of entry or exit can matter more than they would in a busier fund.
