Invesco RAFI Strategic US Small Company ETF (IUSS) is an exchange-traded fund that seeks to track the performance of the Invesco Strategic US Small Company Index by normally investing at least 80% of its total assets in securities comprising the index; the index measures high-quality, small-sized US companies selected and weighted by float-adjusted business-size scores derived from the equally-weighted average of sales, operating cash flow, total return of capital, and book value over the prior five years, with further filtering by quality scores based on efficiency and growth metrics before annual reconstitution. Eligible securities ranked in the top 90% by business-size score qualify, with the top 80% by quality score included, providing exposure to small-cap US equities across diversified sectors including industrials, financials, information technology, consumer discretionary, and health care; the fund targets growth and value stocks of small-cap companies with a focus on fundamental metrics rather than market capitalization. Launched on September 12, 2018, and domiciled in the United States with legal registration in Wilmington, Delaware, the ETF operates primarily in US equity markets and lists on Nasdaq.
The fund features a total expense ratio of 0.19%, a 30-day SEC yield of approximately 1.59%, and holds around 548 securities with a weighted average market capitalization reflecting small-cap focus; assets under management stand at roughly $89 million, with quarterly dividend distributions. Geographically, its holdings are concentrated in the United States at over 98%, with minor exposure to international locations such as Switzerland, Ireland, and the United Kingdom through select securities.
Recent developments include sustained active trading and performance reporting through 2025, with year-to-date returns around 4.62% as of June 30, 2025, alongside ongoing index reconstitution and portfolio rebalancing; the ETF maintains its core methodology amid a value-focused small-cap environment highlighted in mid-2025 analyses emphasizing lower risk profiles. No major acquisitions, partnerships, funding rounds, or structural changes specific to IUSS have been reported in the last 1-2 years, reflecting operational stability under management by Invesco Capital Management LLC, with key portfolio managers including Peter Hubbard, Michael Jeanette, Tony Seisser, and Pratik Doshi.
