Invesco S&P SmallCap 600 Pure Growth ETF (RZG) is an exchange-traded fund that tracks the S&P SmallCap 600 Pure Growth Index, measuring the performance of small-cap U.S. equities exhibiting strong growth characteristics based on sales growth, earnings change to price, and momentum risk factors. The fund invests at least 90% of its total assets in securities comprising the index, which is rebalanced annually and may result in non-diversified status due to market capitalization shifts without shareholder approval; it provides exposure to sectors including energy, consumer staples, industrials, financials, materials, healthcare, consumer discretionary, information technology, and telecommunication services. Launched on March 1, 2006, and domiciled in the United States, RZG is issued by Invesco Ltd., a global investment management firm founded in 1935 (with roots tracing to Investment Counsel, Inc. in Atlanta), headquartered in Atlanta, Georgia, and operating in over 20 countries worldwide. As of late 2025, the fund manages approximately $100 million in assets under management, with an expense ratio of 0.35%, quarterly dividend payouts yielding around 0.64%, and holdings typically numbering 130-140 securities focused on pure growth small-cap companies. Recent developments include institutional investors such as Envestnet Asset Management increasing holdings by 13.3% in Q2 2025, alongside portfolio adjustments like new positions in Veracyte, Inc. and shifts in top holdings including Protagonist Therapeutics, DXP Enterprises, and InterDigital; Invesco itself has advanced its ETF offerings with launches of three active ETFs in May 2025 and other systematic active strategies, though no specific rebranding, acquisitions, or funding rounds directly impacted RZG in the last 1-2 years.
