Invesco RAFI Emerging Markets ETF (PXH)

The Invesco RAFI Emerging Markets ETF (ticker: PXH) provides exposure to publicly traded companies in developing economies—China, India, Brazil, Mexico, Russia, South Korea, Taiwan, and others—using the same fundamental-indexing approach that defines Invesco’s RAFI family. Where traditional emerging-market ETFs weight stocks by market capitalization (and thus concentrate heavily in the largest, most recently popular names), PXH weights by earnings, cash flow, sales, and book value, creating a portfolio tilted toward cheaper and more profitable companies across the developing world.

The Origins of RAFI Emerging Markets

The RAFI methodology arrived in the late 2000s as a systematic response to cap-weighting’s mechanical tendency to overweight expensive stocks at the peak of bubbles. Research Affiliates, the firm behind the index, published academic work showing that portfolios weighted by fundamental economic metrics (what a company actually earns and owns) outperformed market-cap-weighted competitors over long horizons, particularly in value-rich periods and markets prone to boom-bust cycles—a description that fits emerging markets precisely.

Invesco licensed the RAFI index family in the early 2010s and launched a suite of equity ETFs built on the methodology. The Emerging Markets fund arrived in 2013, initially smaller and less trafficked than cap-weighted alternatives like iShares MSCI Emerging Markets, but steadily accumulated assets as investors grew comfortable with the fundamental-weighting thesis. Over the fund’s lifetime, it has experienced the full sweep of emerging-market cycles: the optimism of 2013–2014, the China-shock downturn of 2015–2016, the rebound of 2017, the trade-war turbulence of 2018–2019, and the pandemic shocks and subsequent volatility of the 2020s.

The Emerging-Markets Landscape Inside PXH

The FTSE RAFI Emerging Markets 1000 index includes roughly 1,000 stocks across more than 20 developing economies. China and Hong Kong together typically comprise 25–35% of the portfolio, India another 10–15%, with Brazil, Russia, Mexico, South Korea, Taiwan, and others filling out the remainder. The geography shift from year to year reflects both emerging-market performance and regular rebalancing.

Sector composition within PXH tends to look different from cap-weighted emerging-market funds, particularly regarding China. In a cap-weighted emerging-market index, Chinese technology and internet companies (Alibaba, Tencent, Baidu, and similar firms) loom large because of their enormous market values. PXH’s fundamental weighting reduces that concentration—a high-priced growth company ranks smaller by earnings or book value than it does by market cap. As a result, PXH typically holds more of the mundane but profitable Chinese manufacturers, financials, and utilities that cap-weighted funds automatically underweight. This makes it a structurally different vehicle for accessing China.

The fund’s broader portfolio spans industrials, financials, consumer goods, technology, materials, and energy. Brazil contributes resources and agricultural exposure; Mexico brings both industrials and consumer companies; India adds technology services and manufacturing alongside financial and materials firms.

Riding Emerging-Market Volatility

Emerging-market equities experience larger price swings than developed markets, driven by macroeconomic surprises, currency shifts, commodity cycles, and geopolitical tensions. PXH inherits those oscillations. A Chinese growth scare, a Brazilian political crisis, capital flight from an emerging-market currency, or a commodity price collapse will ripple through the fund’s value.

The advantage of fundamental weighting in this context is moderate but real. When emerging-market excitement inflates certain sectors or countries beyond their economic weight—as happened with tech in 2020–2021—a cap-weighted fund rides the bubble higher; a fundamental fund owns less of it. When the bubble bursts, the fundamental fund has less to give back. Over long periods and multiple cycles, this dampening effect has added a few basis points of excess return, though it is not guaranteed in any single year or cycle.

Costs and Currency Exposure

PXH trades as a standard passively managed ETF with a low expense ratio and tight spreads, making entry and exit costs negligible. The fund holds a fixed portfolio of roughly 1,000 stocks and rebalances periodically to maintain the fundamental-weighting discipline.

Like all emerging-market funds, PXH is exposed to currency movements. Holdings are in rupees, yuan, reals, rubles, pesos, and other emerging-market currencies. A U.S. investor buying PXH absorbs whatever gains or losses result from those currencies strengthening or weakening relative to the dollar. In bull markets for emerging-market currencies (often tied to commodity cycles or faster growth differentials), this amplifies returns; in downturns, it deepens losses. Over very long periods, currency moves roughly balance out, but any 3–5 year window can show significant currency drag or contribution.

Who Uses It and When

PXH is popular among core-and-explore investors treating emerging markets as a satellite holding within a diversified portfolio. Asset allocators often include some emerging-market exposure for return potential and portfolio diversification—developing economies grow faster than developed ones, even if they are more volatile. Traditional cap-weighted emerging-market funds still dominate by assets, but PXH attracts those who believe the fundamental tilt adds value, either because value generally outperforms over time or because emerging markets are cyclically cheap relative to history.

The fund is also used by tactical traders and systematic portfolios rotating between international regions and styles. During periods when emerging markets are rising and value is in favour, PXH can outperform—doubling down on both tailwinds. In the opposite environment, it will lag both cap-weighted emerging-market indexes and developed-market alternatives.

How to Research It

Start with the fund’s prospectus and fact sheet, which detail the underlying index, holdings, and sector breakdown. The FTSE RAFI Emerging Markets index construction rules are public; understanding exactly how rebalancing happens and which countries dominate is essential. Compare the portfolio to a cap-weighted emerging-market fund side by side—you will immediately see the differences in Chinese tech concentration, regional balance, and sector composition.

Historical performance matters less than understanding the methodology and your own conviction about value investing in emerging markets. If you believe developing-market equities will outperform developed markets over the long term, and you believe fundamental weighting will add value within that emerging-market exposure, PXH is a disciplined, low-cost way to implement that view. If you are agnostic on either front, a traditional market-cap-weighted emerging-market ETF is simpler and equally valid.
