Pacer Swan SOS Flex (October) ETF (PSFO) is an actively managed exchange-traded fund that seeks to provide investors with specific structured outcomes based on the performance of the SPDR S&P 500 ETF Trust (SPY), including upside returns up to a predefined cap and downside buffers against the first 20% of SPY losses (with a flex buffer declining 2% for every 1% SPY loss between -20% and -40%), over approximately one-year investment periods beginning each October; the fund invests substantially all of its assets in customizable FLEX Options guaranteed by the Options Clearing Corporation. Launched in September 2021 and sub-advised by Swan Global Management, LLC, PSFO forms part of the broader Pacer Swan SOS ETF family offered by Pacer ETFs, headquartered in Malvern, Pennsylvania, which was founded in 2015 and distributes strategy-driven ETFs focused on risk mitigation, growth, and income through series such as Trendpilot, Cash Cows, and Structured Outcome Strategies. Pacer ETFs targets financial advisors and institutional investors seeking deliberate risk management in U.S. equity exposure, with products available primarily in the United States and recent expansions into European markets via UCITS versions.
In recent developments, Pacer ETFs marked strong asset growth in 2024, increasing from $35 billion to over $46 billion in assets under management (a 31% rise) while launching 10 new funds, including extensions to its Cash Cows and Structured Outcome series; the firm also entered European markets with Cash Cows UCITS products, earned multiple industry awards, and announced updated caps for the October SOS series (including PSFO at 13.31% gross for the period October 1, 2024, to September 30, 2025). Additionally, Pacer Financial, the affiliated distributor, formed a strategic partnership with Save in November 2025 to integrate select Pacer ETFs into innovative cash-management solutions. These initiatives underscore Pacer ETFs' focus on expanding its global footprint, enhancing product innovation, and reinforcing its position as a leader in rules-based, outcome-oriented strategies without recent acquisitions or reorganizations noted.
