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

RBCProShares Russell 2000 Dynamic Buffer ETF

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.

RB No data

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.

RB No data

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

RB No data

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
