Developed vs emerging markets over 15 years?
This page compares 15 years of steady monthly investing into an ex-US developed-markets ETF (EFA) and an emerging-markets ETF (EEM), using the comparison calculator. By pitting the two regions directly against each other without the US, it shows the character and cost of regional diversification.

Method · Comparison
The key is that 'high-growth region = high-return stocks' does not always hold, and regional leadership also rotates. Emerging markets carry high growth expectations but also currency, political, and liquidity risks that can make swings large and drawdowns deep. Developed markets are comparatively stable but can lag when growth engines are weak. In the comparison calculator, review each region's ending balance together with its maximum drawdown and recovery period. The point is less which region is superior and more to understand when regional diversification helps and when it exacts a cost.
Open in comparison calculatorWhy this period and asset
EFA comprises developed-market stocks outside the US—Europe, Japan, Australia, and others—while EEM comprises emerging-market stocks from China, India, Taiwan, Korea, Brazil, and more. There has long been an assumption that 'emerging markets grow fast, so their stocks return more,' but the past 15 years told a different story. Over this period, US stocks led sharply under Big Tech, and as a result both ex-US developed and emerging markets often lagged. Between the two regions, weak currencies, commodity cycles, and country-specific risks made leadership alternate by period. In short, this comparison shows the picture when you choose regions 'without the US.'
Caveats & limits
This comparison reflects one specific past period, and which side leads can change greatly with the start or end date. Past performance does not guarantee the future. Emerging markets carry sizable currency, political, and liquidity risks, and in real investing, fees, taxes, and exchange rates (for dollar-denominated assets) affect outcomes. This page recommends no purchase; it is educational material comparing character.

Frequently asked questions
Which is better, developed or emerging markets?
Neither is always better. Over the past 15 years both lagged the US, and leadership between them alternated by period. Since regional leadership rotates, use the comparison calculator to view return and drawdown side by side.
Emerging markets grow faster, so why didn't their returns lead?
Economic growth and stock returns do not always move together. When weak currencies, commodity cycles, and country-specific risks combine, stock returns can lag even where growth is high.
What should I use as the basis for comparison?
Don't look only at the final return; also review maximum drawdown, time underwater, and recovery period. Emerging markets can be especially volatile with deep drawdowns, so whether you can withstand the swings shapes the real outcome.
