AllianzIM U.S. Small Cap Buffer15 ETF is a non-diversified exchange-traded fund managed by Allianz Investment Management LLC that seeks to provide risk-managed exposure to U.S. small-cap equities. The fund seeks, over successive three-month outcome periods, to match the share-price return of the iShares Russell 2000 ETF, up to a predetermined upside cap, while buffering the first 15% of losses in the underlying ETF, before the effects of management fees and other expenses. Its investment strategy uses options and other instruments linked to the iShares Russell 2000 ETF to provide capped upside participation and defined downside protection; the upside cap and buffer reset quarterly and are reduced for fund expenses. The fund is designed for investors seeking exposure to the Russell 2000 small-cap equity market with a stated level of downside mitigation, rather than full uncapped participation in underlying-market gains. AllianzIM U.S. Small Cap Buffer15 ETF commenced operations on March 31, 2026, and began trading under the ticker QBKF on Cboe BZX on April 1, 2026. It is part of Allianz Investment Management LLC’s AllianzIM buffered ETF platform and is offered in the United States through AIM ETF Products Trust. Its most significant recent development is its 2026 launch as part of AllianzIM’s expansion of its buffered ETF suite, introducing a quarterly-reset, single-ticker small-cap strategy that references the iShares Russell 2000 ETF and provides a 15% downside buffer with one-for-one upside exposure up to a cap.
