KOCTBInnovator U.S. Small Cap Power Buffer ETF

RBCProShares Russell 2000 Dynamic Buffer ETF

In short

KOCT Small-cap exposure with a seatbelt. KOCT tracks IWM up to a yearly cap while absorbing the first 15% of losses, resetting each October 1. A 2019 original in a corner where most buffer funds are built on the S&P 500.

RB No data

Stated mandate

KOCT The Fund seeks to track the return of the iShares Russell 2000 ETF, subject to a predetermined upside cap, while protecting against the first 15% of losses during the outcome period.

RB No data

Why people hold it

  • KOCT The contract is plain: track the iShares Russell 2000 ETF up to a preset cap, with the first 15% of losses over the one-year outcome period absorbed first.innovatoretfs.com
  • Rare air: it listed October 1, 2019 in Innovator's first small-cap buffer wave. Most defined-outcome ETFs wrap the S&P 500, not the Russell 2000.accessnewswire.com
  • Fee lands at 0.79%, the middle of its small-cap buffer group, and the fund rates in the upper half of that group on our review.
  • You pick your calendar. This is the October reset; siblings KJAN, KAPR and KJUL run the same 15% buffer off other quarters.

RB No data

Worth knowing

  • KOCT The cap is the price of the cushion. A blistering small-cap year gets trimmed, and the cap is reset for each new outcome period starting October 1.
  • Timing matters: Innovator notes the stated outcomes apply to holders from the first day of the outcome period through the last. Buy mid-period and your own cap and buffer differ.innovatoretfs.com
  • Trading is light versus mainstream small-cap funds, and the options-based structure isn't built to throw off income.
