AllianzIM U.S. Large Cap 6 Month Buffer10 May/Nov ETF (SIXZ) is an actively managed exchange-traded fund that seeks to track the price return of the SPDR S&P 500 ETF Trust (SPY) up to a stated cap, while providing a buffer against the first 10% of losses over a defined six-month outcome period that resets in May and November; the fund utilizes FLEX options and collateral with an expense ratio of 0.74%. SIXZ forms part of Allianz Investment Management LLC's (AllianzIM) suite of defined outcome buffer ETFs, which includes sister funds such as the U.S. Large Cap 6 Month Buffer10 Jun/Dec ETF (SIXD), Mar/Sep ETF (SIXP), and Apr/Oct ETF (SIXO), targeting investors seeking structured equity exposure with downside protection and periodic resets for enhanced flexibility; the series collectively manages nearly $250 million in assets. AllianzIM, a registered investment adviser and wholly owned subsidiary of Allianz Life Insurance Company of North America (headquartered in Minneapolis, Minnesota), operates within the global Allianz Group network established in 2007, leveraging proprietary hedging platforms to manage buffered strategies linked to large-cap U.S. equities for retail and institutional clients primarily in North America.
In recent developments, AllianzIM completed its 6 Month Buffer10 ETF series with the launch of SIXD in June 2024, following the April 2024 inception of SIXZ, enabling twice-annual resets compared to traditional annual buffer products. The firm expanded its buffer offerings in 2025 by launching quarterly-reset ETFs including the U.S. Equity Buffer100 Protection ETF (AIOO) and U.S. Equity Buffer15 ETF (QBSF) in July, as well as the Buffer15 Uncapped Allocation ETF in March as a fund-of-funds providing laddered exposure to uncapped upside with 15% buffers; additionally, AllianzIM announced plans in December 2025 to transfer listings of multiple buffered ETFs, including SIXZ, from NYSE Arca to Cboe BZX Exchange effective around December 22, 2025. These expansions build on AllianzIM's core risk management expertise, supporting over $155 billion in hedged assets globally through Allianz SE's infrastructure, without reported acquisitions, funding rounds, or partnerships specific to the buffer ETF segment in the last two years.
