IBUF vs RSJN

IBUFBInnovator International Developed 10 Buffer ETF

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

In short

IBUF Most buffer ETFs aim at the S&P 500. IBUF looks overseas, using the iShares MSCI EAFE ETF as its reference and buffering the first 10% of losses over each quarterly outcome period, with upside capped in return.

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

IBUF The Fund uses a quarterly defined-outcome strategy based on the iShares MSCI EAFE ETF. It seeks to provide gains up to a cap while buffering the first 10% of reference-asset losses for investors holding through the full outcome period.

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

• IBUF Buffer funds crowd around US large caps. This one references the iShares MSCI EAFE ETF, so the 10% cushion sits on developed markets outside the US.
• The outcome period runs a quarter, not a year, so the buffer and the cap reset four times annually rather than once.
• At 0.85% a year, it comes in under the median fee among the buffer funds we track.
• Sits among the strongest implementations in its buffer-fund peer group on our review.

• 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

• IBUF The price of the cushion is a ceiling. Gains above each quarter's cap are given up, and that cap is reset at the start of every outcome period.
• The 10% buffer is designed for investors who hold a full outcome period. Buy mid-quarter and your actual cushion and cap differ from the stated terms.
• Launched in July 2024 and lightly traded, so the track record is short and spreads can run wider than on large index funds.

• 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.
