This is a U.S. large-cap equity ETF that tracks the RAFI Fundamental Select US 1000 Index. It uses a smart-beta approach that weights holdings by fundamental metrics such as book value, cash flow, sales, and dividends—rather than market capitalization—in order to reduce the impact of market price fluctuations.

It is well suited for long-term investors seeking broad diversification across large-cap stocks with a value tilt that differs from a pure market-cap-weighted approach.

The ETF is passively managed (index-tracking) by Invesco.

Holdings are weighted based on a company's size as measured by four fundamental metrics—book value, cash flow, sales, and dividends—rather than market capitalization. This approach helps mitigate the market-cap-weighted tendency for overvalued stocks to take up disproportionate weight, resulting in a broadly diversified portfolio with a stronger value orientation.

• Weighting methodology based on fundamentals rather than market capitalization
• A clearly value-tilted profile relative to market-cap-weighted core ETFs

Size and Cost of the Invesco RAFI US 1000 ETF (Assets Under Management and Expense Ratio)

Assets under management (AUM) stand at $10.1B, with a total expense ratio of 0.34% annually.

The weighting methodology differs fundamentally from market-cap-weighted core ETFs, and its higher value-stock exposure can lead to performance divergence depending on the market environment.

Performance and Flows of the Invesco RAFI US 1000 ETF

Given its strong value tilt, the fund tends to diverge in performance from market-cap-weighted core ETFs during periods led by growth stocks versus those favoring value names. Recent trends have also shown volatility in line with shifting market style preferences.

Fund flows continue to respond to demand for smart-beta and factor investing, with capital generally flowing in from investors seeking differentiated exposure relative to market-cap-weighted core ETFs. The direction of flows can shift during periods of style rotation.

Its strengths lie in the value orientation delivered through fundamental weighting and broad diversification, while its weaknesses include a somewhat higher fee versus market-cap-weighted core ETFs and the risk of style headwinds.

The fundamental and multifactor ETFs shown in the table share a similar weighting philosophy while differing in provider and fees, making them natural comparators. For a direct comparison among ETFs that track U.S. large caps using market-cap weighting, the broad core ETF VOO is a key reference, while investors seeking a heavier value tilt may also consider the value ETF VTV.

Points to review before investing in PRF. Given that the fund's fundamental weighting approach is its defining feature, it is advisable to confirm the weighting methodology, value tilt, and costs in advance.

The main source of variability is that the value tilt and fundamental weighting can produce a different performance trajectory from market-cap-weighted core ETFs depending on the prevailing market style. Periods of strong growth-stock leadership may bring extended periods of relative underperformance.

The fund is a suitable choice for investors seeking broad diversification across large caps with a value orientation that differs from market-cap weighting. For investors who prioritize simple core exposure and the lowest cost, a market-cap-weighted ETF such as VOO may be more appropriate, while PRF is worth considering for those seeking the differentiation offered by fundamental weighting.
