BUFF vs IVVM

BUFFBInnovator Laddered Allocation Power Buffer ETF

IVVMBiShares Large Cap Moderate Quarterly Laddered ETF

In short

BUFF Buffer ETFs usually make you pick a start month. BUFF skips the choice: equal slices of 12 Innovator Power Buffer ETFs, one resetting every month, each buffering the first 15% of a 12-month SPY drop in exchange for a capped upside.

IVVM Most buffer funds make you pick a start date. IVVM runs overlapping three-month tranches on IVV, each cushioning roughly the first 5% of losses in exchange for a cap, so no single reset date decides everything.

Stated mandate

BUFF The fund seeks exposure to the FTSE Laddered Power Buffer Strategy Index, which equally allocates among 12 U.S. Equity Power Buffer ETFs. Those underlying ETFs seek U.S. equity upside subject to caps while buffering the first 15% of losses.

IVVM The fund seeks exposure to large-cap U.S. equities while using staggered-maturity buffers to protect approximately the first 5% of losses. It accepts limited upside and uses the laddered structure to reduce timing risk.

Why people hold it

• BUFF One ticket, twelve vintages. Each underlying Power Buffer ETF resets in a different month, so your entry date matters less than with a single-vintage buffer fund.innovatoretfs.com
• Each sleeve seeks SPY's return up to a cap while absorbing the first 15% of an SPY decline over that sleeve's outcome period, before fees and expenses.innovatoretfs.com
• Built to sit still: the index rebalances semi-annually and Innovator states the fund can be held indefinitely, with no outcome period for you to roll.innovatoretfs.com
• Listed in 2016, running this laddered strategy since its August 2020 conversion, and now a billion-dollar-plus fund sitting in the upper half of its peer group.innovatoretfs.com

• IVVM 0.50% net of a waiver through June 30, 2028 (0.53% gross), below the category median and well under Innovator's laddered Power Buffer fund BUFF at 0.89%.ishares.com
• Staggered tranches of roughly three-month FLEX options, rolling on a rhythm, spread out the entry-point risk that single-period buffer funds carry.ishares.com
• Born in 2023 as a plain quarterly buffer fund, rebuilt as a ladder in October 2025, and one of the stronger builds in its laddered-buffer peer group.sec.gov
• The reference asset is BlackRock's own S&P 500 workhorse, IVV, inside a standard 1940 Act ETF wrapper that trades all day on an exchange.sec.gov

Worth knowing

• BUFF At 0.89% it sits near the category median, but some laddered rivals run cheaper: ALDB at 0.30%, PBFR at 0.50% (and PBFR tracks the same declared index).
• Caps cut both ways. Laddering smooths the caps across twelve vintages, and in a roaring market the capped sleeves leave upside on the table.innovatoretfs.com
• Not an income vehicle: it has not been paying regular distributions, so returns have to come from price.

• IVVM Each tranche caps the upside, and caps are reset at every roll, so a hot S&P 500 stretch leaves the fund behind plain index exposure.ishares.com
• The cushion is thin by design: approximately the first 5% of losses per tranche, with declines past that borne in full, and fund fees come off the top.sec.gov
• Exposure follows IVV's share price, not its dividends, and the fund trades thinly on a modest asset base, so spreads can run wider than on index giants.sec.gov
