IBFR vs IBUF

IBFRCInnovator International Developed Managed 10 Buffer ETF

IBUFBInnovator International Developed 10 Buffer ETF

In short

IBFR Most buffer funds pay for downside protection with a ceiling on gains. Innovator's Managed 10 flips the deal: a roughly 10% loss buffer on developed-market stocks outside the US and Canada, with the upside left uncapped.

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.

Stated mandate

IBFR The Fund seeks capital appreciation from uncapped participation in large- and mid-cap developed-market equities outside the United States and Canada, while limiting losses through its hedging strategy.

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.

Why people hold it

• IBFR Uncapped by design: the mandate seeks full participation in large- and mid-cap developed-market stocks outside the US and Canada, with hedges there to limit losses.
• Points the buffer overseas instead of at US equities, tracking the MSCI EAFE opportunity set across roughly 300 large- and mid-cap names.
• Actively managed buffer, so the hedge is a manager decision rather than a static calendar formula.
• 0.85% expense ratio, right in the range buffer strategies typically charge, including Innovator's international buffer sibling IBUF.

• 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.

Worth knowing

• IBFR Launched in 2026, so there is no long record showing how the hedge behaves across different markets.
• Small asset base and light trading so far, which can mean wider spreads than the category's heavyweights.
• A buffer limits losses, it does not remove them, and the cost of running the hedge comes out of returns. Payouts land once or twice a year, not monthly.

• 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.
