IVVM vs SPBX

IVVMBiShares Large Cap Moderate Quarterly Laddered ETF

SPBXCAllianzIM 6 Month Buffer10 Allocation ETF

In short

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.

SPBX Most buffer ETFs make you pick a start month and babysit the roll. SPBX holds AllianzIM's entire six-month Buffer10 lineup in equal weight, so one sleeve resets to a fresh 10% buffer and a new cap every month.

Stated mandate

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.

SPBX The Fund seeks capital appreciation while mitigating downside risk through a laddered portfolio of six U.S. equity buffered ETFs tied to SPY exposure.

Why people hold it

• 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

• SPBX One ticker, six sleeves. Each underlying fund buffers the first 10% of SPDR S&P 500 ETF Trust losses over its own six-month window, and one of them resets with a fresh buffer and a new cap each month.allianzim.comsec.gov
• Six-month outcome periods re-strike twice a year, so the buffer and cap reset against more recent index levels than the standard 12-month buffered ETF.allianzim.comallianzim.com 2
• Laddering across the full suite means no single start date defines your result. You hold six staggered periods at once instead of one, and the rebalancing work sits with the manager.allianzim.com
• At 0.79% all-in, it prices right at the middle of the buffer-fund pack rather than at a premium for the wrapper.

Worth knowing

• 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

• SPBX Most of that 0.79% is the underlying funds' own fees. The 0.10% management fee is cut to 0.05% only through at least February 2027, and cheaper ladders exist (BUFP at 0.50%).allianzim.com
• Every sleeve's upside stops at its cap, and the 10% buffer is stated before fees and measured over that sleeve's six-month period, not from the day you buy.allianzim.comallianzim.com 2
• Launched in 2025 and lightly traded, so the record is short by buffer-fund standards and spreads can run wider than the category's largest names.
