ARKD vs KBFR

ARKDFARK DIET Q1 Buffer ETF

KBFRBInnovator U.S. Small Cap Managed 10 Buffer ETF

In short

ARKD A buffer ETF pointed at ARK's flagship innovation fund instead of a stock index: it absorbs about half of any ARKK decline over the 12-month outcome period, in exchange for the first ~5% of upside and a share of the rest. Fee: 1.44%.

KBFR Small caps with a seatbelt. Innovator's actively managed fund owns roughly 800 U.S. small caps and layers options on top, built around the 10% buffer in its name, and it undercuts the typical buffer fund on fee.

Stated mandate

ARKD ARKD seeks capital appreciation while limiting participation in losses of ARKK to approximately half over each Outcome Period. It participates in ARKK gains above an approximately 5% hurdle, with documented upside participation of 61.20%.

KBFR The Fund seeks long-term capital gains while mitigating overall market risk. It is actively managed and uses equity and option positions to provide risk-managed U.S. small-cap exposure.

Why people hold it

• ARKD Buffer mechanics aimed at ARK's flagship innovation fund, not an index: shareholders take roughly half of any ARKK decline over the 12-month outcome period.sec.gov
• No upside ceiling in its terms. Instead of a cap, it gives up the first ~5% of ARKK's gains and takes a set share above that, struck at each period's start.sec.gov
• A plain 1940 Act ETF wrapper: the outcome comes from the fund's own options book, not a bank's note or an issuer's credit.ark-funds.com

• KBFR Costs 0.79% a year, below the 0.89% typical of buffer funds in its group.
• Actively managed and holds about 800 small caps outright, with the option positions layered on top rather than standing in for the stocks.
• Buffered small-cap exposure is a thin shelf. Its nearest cohort peers cushion international stocks (IBUF), equal-weight U.S. (RSJN) or long Treasuries (TBJL).
• Adds up to one of the stronger overall packages among the buffer funds we grade.

Worth knowing

• ARKD At 1.44%, it carries a higher fee than the typical buffer fund; peers like CBXO (0.69%) and KBFR (0.79%) run leaner.
• The 50% loss share is a haircut, not a floor, and the terms are measured over the full outcome period, so a mid-period entry changes the math.sec.gov
• Launched in 2026, it's a young fund with a small asset base and light trading, which can mean wider spreads.

• KBFR Launched in 2026, so there is little live history behind any read on how it handles a real drawdown.
• Small and thinly traded, so bid-ask spreads and premiums can run wider than in the big buffer names.
• The buffer absorbs a slice of losses, not all of them, and the option overlay means results can part ways with the small-cap market in both directions.
