Emerging markets often disappoint investors for a reason that has little to do with slow growth: economic growth does not automatically become growth in earnings per share. In many emerging markets, new share issuance has historically absorbed a large part of that growth before it reaches existing shareholders.
That is why a country’s GDP can look strong while its long-run investor returns stay weak. The more useful test of an emerging-market fund is its per-share earnings growth, not its country’s GDP forecast.
After fifteen years of disappointing returns, investors are again being told the emerging-market growth story is about to pay off. It rarely does, and the reason is quieter than a bad economy. Using MSCI, Schroders, and JPMorgan data, the illustrative model in this analysis puts one diligent investor’s hidden shortfall at $260,320 over twenty-five years. The title’s fifteen-year gap refers to J.P. Morgan’s recent window for emerging-market earnings-per-share dilution; Priya’s separate twenty-five-year model below shows how a comparable wedge can compound over a saving horizon. This is a long-run, cross-country pattern; any single market or decade can and sometimes does run the other way.
Why Don’t Booming Emerging Economies Deliver Booming Returns?
Emerging economies really are growing two to three times faster than the developed world, and profits ultimately flow from economic output. Allocation models, index providers, and business-news segments repeat that growth premium as settled fact. If growth reliably reached shareholders, the fastest-growing economies would indeed be the best place to invest.
The boom is genuine. The mistake is assuming it lands in the shares you already own rather than in the new ones a growing economy keeps issuing.
Picture a canister of water that a growing economy keeps refilling. Each year there is more water in total. But every year a few more cups crowd under the spout, so any single cup catches a little less. That is roughly what share issuance does to a shareholder’s claim on a country’s earnings.
This analysis is written for anyone who holds or is considering an emerging-markets index fund or ETF and wants to know whether the growth story actually reaches their returns. It is less relevant to single-stock pickers or short-term traders, and it describes long-run averages rather than any one market or decade.
The economies that grew the most have often rewarded their shareholders the least.

The missing link is the difference between aggregate economic growth and earnings growth per share. For a refresher on what one share actually represents, start with what a stock really is.
How Much of Emerging-Market Growth Actually Reaches Shareholders?
Emerging-market shareholders have historically lost far more to dilution than developed-market investors. Schroders measured annual share dilution near 3.2% in emerging markets, versus roughly 0.5% in developed ones, which makes the drag more than six times heavier. J.P. Morgan Asset Management put the recent fifteen-year figure close to 400 basis points a year of EPS headwind, and near 820 basis points in China alone. That gap exists because a large share of rapid growth has been financed through new equity issuance and public offerings, each of which thins the claim existing investors hold on future profits.
Dilution is not the only force at work. Valuation changes, the price paid for expected growth, and the start date of any measurement all matter too. But dilution is the most consistent and measurable of them, which is why it anchors this analysis.
For the long-run backdrop, the Dimson-Marsh-Staunton Yearbook (2026 edition, covering 1900-2025) shows developed markets returning 8.5% a year in nominal terms since 1900, versus 6.9% for emerging markets.

Faster Growth, Weaker Returns: 15 Emerging Markets
| Market | GDP growth | Real stock return |
|---|---|---|
| Argentina | 2.4% | 10.4% |
| Brazil | 2.0% | 13.3% |
| Chile | 4.0% | 14.1% |
| China | 9.4% | -5.5% |
| India | 5.1% | 4.1% |
| Jordan | 0.9% | 1.2% |
| Malaysia | 3.9% | 6.8% |
| Mexico | 1.2% | 15.0% |
| Philippines | 1.8% | 3.1% |
| Portugal | 1.9% | -0.9% |
| Russia | 3.6% | -6.8% |
| South Korea | 4.7% | 4.2% |
| Taiwan | 4.3% | 4.9% |
| Thailand | 4.1% | 5.4% |
| Turkey | 2.4% | 5.0% |
A developed-market investor gives back about half a percent a year to dilution and barely notices. Hold an emerging-markets fund, and that same half-percent has historically run closer to 3.2%, year after year. As J.P. Morgan Asset Management reported, “net dilution has acted as a 400bps per year headwind to EM EPS.” One basis point is a hundredth of a percentage point, so 400 basis points is about four percentage points a year of pressure on per-share earnings.
That headwind falls on earnings per share, which is not the same as a fund’s total return. Dividends, valuation swings, and currency moves all sit on top of it. But over long horizons, persistent EPS dilution is one of the clearest reasons a fast-growing market can leave its shareholders behind.
Why Does Economic Growth Skip Your Earnings Per Share?
Growth reaches an economy’s total output long before it reaches any single share. When a market adds new companies through public offerings, aggregate earnings can rise, yet they are now spread across a larger share count. When an established company issues equity, it raises capital rather than earnings; profits grow only later, and only if that capital is put to work. Either way, when the share count grows faster than earnings, earnings per share lag. MSCI Barra measured this as a 2.3% average gap between real GDP growth and per-share earnings growth across sixteen developed markets from 1969 to 2009. Bernstein and Arnott had labeled the same effect the “two percent dilution” decades earlier.
New shares route tomorrow’s growth to tomorrow’s capital. An IPO or secondary offering enlarges the share count immediately, while any extra earnings from the capital it raises arrive later, if at all, so the growth can flow past the shareholders who already own the company. Issuance is not automatically harmful; it becomes a drag only when the new capital fails to lift earnings enough to offset the larger share count. Retained earnings, debt, and productivity gains can finance growth without issuing stock, which is why some markets pass more of their growth through to shareholders than others.
Before this work, country-allocation models often treated GDP growth as a near-direct proxy for future stock returns. Ritter, and Bernstein and Arnott, reframed growth as a ceiling that dilution and issuance erode before it reaches per-share earnings. The effect also compounds through dividends, since what a company pays per share, not in aggregate, is what an income investor actually keeps after dividend tax drag.
Apparently, consumers and workers rather than the shareholders of existing companies gain all of the benefits of economic growth.

The common thread across Ritter and MSCI Barra is that a country’s economic growth and a shareholder’s per-share return are two different numbers.
Priya’s $260,320 Emerging-Market Gap
Consider Priya, a hypothetical mid-career investor who commits $25,000 plus $500 a month to an emerging-markets sleeve for twenty-five years. She expects the growth story to power an 8% annual return. To make the dilution mechanism visible, this model applies Schroders’ historical, market-level 3.2-percentage-point dilution estimate as a simplifying stress-test adjustment to that assumed 8%. It is not an estimate of what any specific fund will earn. On those assumptions, an 8% path compounds to about $625,707, while the 4.8% dilution-adjusted path reaches roughly $365,387, a difference of $260,320.
This is an illustration of a mechanism, not a forecast. A realized index return already reflects past dilution, and no fund docks a fixed 3.2% from your statement each year. The point of subtracting the wedge is to make a slow, invisible drag visible on a single balance.
Priya is 45, with a 25-year horizon. She starts an emerging-markets allocation with $25,000 and adds $500 a month, on the reasonable assumption that faster-growing economies should eventually support stronger returns. The figure she never sees is the net new issuance inside her index, quietly climbing year after year. She is not careless; she is doing exactly what the growth story tells careful investors to do.
Priya is a hypothetical composite drawn from common mid-career investor patterns, not a real individual.
| Input | Value |
|---|---|
| Age today / target age | 45 / 70 |
| Initial balance | $25,000 |
| Monthly contribution | $500 |
| Time horizon | 25 years |
| Growth-story return | 8.0% a year |
| Dilution-adjusted return | 4.8% a year (8.0% minus the 3.2% wedge) |
Formula: FV = P*m^n + PMT*((m^n-1)/(m-1)), m = (1+r)^(1/12)
Model: naive versus dilution-adjusted compounding, calculated monthly, end of period.
Assumptions: the 8.0% base return is an illustrative assumption, not a forecast. The 3.2% dilution wedge is a historical, market-level average from Schroders, applied here as a simplifying illustration; realized fund returns will differ.
Does not apply to: single-market or single-decade outcomes.
| Year | Growth-story path | Dilution-adjusted | Gap | What the gap could buy |
|---|---|---|---|---|
| Year 5 | $73,206 | $65,346 | $7,859 | a family’s annual health-insurance deductible |
| Year 10 | $144,035 | $116,351 | $27,684 | a reliable used car |
| Year 15 | $248,107 | $180,829 | $67,278 | about one all-in year at a private college |
| Year 20 | $401,023 | $262,342 | $138,682 | a 20% down payment on a $700,000 home (above the U.S. median) |
| Year 25 | $625,707 | $365,387 | $260,320 | roughly four all-in years of private university |
The two paths are illustrative, not forecasts. Their purpose is to show how a persistent per-share earnings gap can compound over a long holding period, which you can watch by visualizing compound interest side by side.
| Year | Growth-story path | Dilution-adjusted |
|---|---|---|
| Year 5 | $73,206 | $65,346 |
| Year 10 | $144,035 | $116,351 |
| Year 15 | $248,107 | $180,829 |
| Year 20 | $401,023 | $262,342 |
| Year 25 | $625,707 | $365,387 |
China is the sharpest version of this story, and it comes with a caveat worth stating up front. Using Ritter’s 2012 MSCI-based data, China grew its economy roughly fivefold while its shareholders lost money in real terms, near -5.5% a year. Later work by Hsu and Ritter, using mainland A-share returns, puts China’s real return modestly positive. So the exact figure depends on which return series you use, even though the dilution mechanism holds under either lens.

Each row holds Priya’s $25,000 start and $500 monthly steady and moves one lever at a time, so every gap isolates a single assumption over her 25 years. “With strategy” is the growth-story return; “without” applies the dilution wedge. The China row uses an 8.2-point wedge, which pushes the adjusted return slightly negative.

| Larger lump | P $50K | $796,919 | $446,105 | $350,814 |
The deepest gap comes from the most-cited growth story of all: China’s 8.2-point wedge turns Priya’s illustrative $625,707 into $170,100, a $455,608 shortfall on these assumptions.
The gap is not a crash you can point to. There is no bad year to blame and no headline to catch it. The difference simply never shows up, spread thin across the years, until something like a private-university education has quietly moved out of reach.
How Should You Actually Invest in Emerging Markets?
The dilution story is not a reason to abandon emerging markets. Over the full 1988 to 2011 window Jay Ritter studied, emerging markets nearly matched the S&P 500, and through the 2000s they clearly beat it, so start dates matter enormously. Hsu and Ritter found in 2022 that earnings-per-share growth predicted emerging-market returns far better than GDP growth did. Markets and funds that grow profits per share, rather than merely issuing stock, still pass most of that growth through to the shareholders who own them. The fix is selection, not avoidance.
Start dates cut both ways. Measured in nominal terms since 1960, emerging markets led at 10.9% a year against developed markets’ 9.6%, so the winner flips depending on where you start the clock.

Step 1: Measure Dilution Directly
Measure dilution at the level that actually matters. Do not use the ETF’s own shares outstanding, which mostly track fund flows and the creation-redemption process, not the dilution of the companies it holds. Look instead at the index’s net equity issuance, or the weighted change in shares outstanding across the fund’s underlying companies. Ritter’s 2012 study compared per-capita GDP growth against real equity returns and found them negatively correlated. A country’s headline growth rate tells you little; the underlying issuance trend tells you plenty.
Step 2: Screen for EPS Growth, Not GDP
Screen for earnings-per-share growth rather than GDP growth. Hsu and Ritter found in 2022 that EPS growth predicted emerging-market returns far better than economic growth did, which barely correlated with returns at all. Favor funds where profit per share is rising, not just the raw number of listed shares.

Step 3: Watch the Share-Count Trend
Check the share-count trend before you trust the growth forecast. Funds tracking indexes heavy with serial issuers, as many Chinese names have been, pass less growth through to you. India is the counterexample. Many listed firms there fund expansion from profits, so more of their growth reaches shareholders.
Step 4: Size the Position for Dilution
Size the position for what dilution leaves behind, not the headline growth. On Priya’s illustrative path a 3.2% annual wedge turned an expected $625,707 into $365,387 over twenty-five years. Treat emerging markets as a measured, EPS-screened sleeve rather than a bet on a country’s GDP forecast.
None of these three signals is sufficient on its own. EPS growth, net share issuance, and dividends per share are worth checking together, but valuation, currency, governance, sector exposure, fees, and diversification still shape the outcome. Weight emerging-market exposure toward markets and funds with low share issuance and rising dividends per share, and steer clear of dividend yield traps that dress up shrinking payouts as income.
Screening for low issuance may narrow part of that $260,320 gap over 25 years, though it will not remove every source of underperformance. Next time a fund sells you a country’s growth, ask whether earnings per share is growing or just the share count. We will refresh these figures when Dimson-Marsh-Staunton and JPMorgan publish their next annual data.
Emerging Markets: Frequently Asked Questions
The short version is that emerging-market growth has been real, but much of it never reached existing shareholders. Ritter’s cross-country data shows economic growth and stock returns barely correlate, and sometimes move in opposite directions. Dilution is a leading reason: public offerings and new issuance route growth to fresh capital before it lifts earnings per share, running about 3.2% a year in emerging markets by Schroders’ estimate. The practical takeaway is to screen emerging markets on per-share fundamentals rather than headline GDP forecasts.
Does GDP growth lead to higher stock returns?
GDP growth does not reliably lead to higher stock returns, and across countries the two barely move together. Jay Ritter’s 1900 to 2011 data put the correlation slightly negative, near -0.41 for emerging markets from 1988 to 2011. China is the clearest case: using Ritter’s MSCI-based series, its economy grew close to 10% a year from 1993 to 2011 while its real stock return was about -5.5%, though later A-share-based work makes that figure less extreme. Output flows to workers, consumers, and new firms, reaching your shares only after issuance dilutes the pool.
How does dilution lower emerging-market returns?
Share dilution lowers emerging-market returns by handing a growing economy’s gains to new shares before they reach the ones you own. IPOs and secondary offerings raise total earnings, but each dollar of profit now backs more shares. Schroders pegged that annual leak near 3.2%, more than six times the 0.5% developed-market investors accept. J.P. Morgan sized the recent fifteen-year headwind on EPS near 400 basis points, and 820 in China. Aggregate profit climbs while earnings per share barely move.
Should I avoid emerging markets entirely?
Avoiding emerging markets entirely is an overreaction, because the problem is selection rather than the asset class. Across the 1988 to 2011 window Ritter studied, emerging markets nearly matched the S&P 500, and beat it through the 2000s. The better fix is to screen for what dilution leaves behind. Hsu and Ritter showed in 2022 that per-share earnings growth forecast returns far better than GDP growth. Favor funds that grow profit per share, not just share count, as many Indian firms do.
The Bottom Line on Why Emerging Markets Underperform
A century of data settles the question fairly plainly. Ritter tracked economic growth against shareholder returns across dozens of countries and found them nearly unrelated, sometimes moving in opposite directions. Dilution is a leading reason. A boom that finances itself through new shares hands tomorrow’s growth to tomorrow’s owners, so the earnings pool widens while any one investor’s slice of it thins. That is why the better tool is a screen, not a forecast. Judge an emerging-market fund by the earnings-per-share growth and the net-issuance trend of its underlying holdings, not by the GDP number its country is projected to post.
The economy keeps refilling a bigger canister each year, yet every shareholder’s cup can still pour out a little less.
The economy may have delivered the growth investors expected. Existing shareholders did not always receive the same growth per share. Under these simplifying assumptions, applying the 3.2-point wedge produces a $260,320 difference over 25 years on a single $25,000 sleeve, which is what makes an abstract percentage concrete.
Before you trust an emerging-markets fund’s growth story, check the index’s EPS growth and the net issuance trend of its underlying companies, not the ETF’s own unit count.
