KBFR vs RSJN

KBFRBInnovator U.S. Small Cap Managed 10 Buffer ETF

RSJNBFT Vest U.S. Equity Equal Weight Buffer ETF - June

In short

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.

RSJN Most buffer ETFs are bolted onto the cap-weighted S&P 500, where a few megacaps call the shots. RSJN buffers the equal-weight version instead: the same 500-odd names, spread evenly, with the first 10% of losses absorbed over each June-to-June period.

Stated mandate

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.

RSJN Seeks returns matching the Underlying ETF’s price return up to a predetermined cap, while buffering the first 10% of its losses during the June 22, 2026–June 17, 2027 Target Outcome Period.

Why people hold it

• 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.

• RSJN The reference asset is the Invesco S&P 500 Equal Weight ETF, so roughly 500 companies carry similar weight and no single megacap steers the outcome. A rare flavor in a cohort built mostly on cap-weighted indexes.ftportfolios.com
• The rules are written down, not left to a manager's judgment: absorb the first 10% of the underlying ETF's price decline over the stated outcome period, in exchange for an upside cap set at each period's start.ftportfolios.com
• Expense ratio is 0.85%, right in line with what defined-outcome funds in its peer group charge for the same options plumbing.
• June is one of three siblings on the same equal-weight reference (March and September round it out), so start dates can be laddered instead of hitched to one calendar.ftportfolios.com

Worth knowing

• 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.

• RSJN The buffer is paid for with a ceiling: gains in the underlying ETF above the period's cap don't come through. Terms also reset each June, so entering mid-period changes your effective cap and remaining buffer.ftportfolios.com
• The target is price return on the underlying ETF, held via FLEX options, so dividends from those 500 companies are not passed through. Income is not part of the design.ftportfolios.com
• Trading is light next to the biggest buffer funds, so spreads and limit orders matter more here than with a mega-cap-index product.
