Abacus FCF Leaders ETF (ABFL) is an actively managed exchange-traded fund that seeks long-term capital appreciation by investing primarily in U.S. equities selected for superior free cash flow characteristics, aiming to outperform the Russell 3000 Index with lower volatility; the fund employs a proprietary FCF Leaders Model emphasizing free cash flow return on invested capital (FCF-ROIC), prudent capital expenditure, low accruals, high cash flow margins, and strong asset turnover to identify 80 to 150 stocks from the top decile of ranked U.S. companies, weighted by modified market capitalization; it focuses on total market equity across large-, mid-, and small-cap segments, with approximately 99% allocation to U.S. stocks and minimal cash holdings. Launched on September 27, 2016, and domiciled in the United States, ABFL trades on Cboe BZX under ticker ABFL with assets under management exceeding $700 million, an expense ratio of 0.49%, and quarterly distributions; it is issued by Abacus FCF ETF Trust and managed by Abacus FCF Advisors LLC, a subsidiary of Abacus Life Inc. following the 2024 acquisition of FCF Advisors. The fund previously operated as TrimTabs U.S. Free Cash Flow Quality ETF under ticker TTAC until November 13, 2024, and as FCF US Quality ETF prior, reflecting a strategic rebranding to emphasize free cash flow leadership; in February 2025, Abacus FCF Advisors completed its full rebrand from FCF Advisors, launched the complementary Abacus FCF Small Cap Leaders ETF (ABLS), reduced management fees by 5-10 basis points across its ETF suite including ABFL, and introduced an 18-month 20 basis point fee waiver on select funds.
