US vs emerging markets over 15 years?
This page compares 15 years of steady monthly investing into an S&P 500 ETF (SPY) and an emerging-markets ETF (EEM), using the comparison calculator. It tests the 'emerging markets grow fast' assumption against the actual gap in the data.

Method · Comparison
The key is that 'high-growth country = high-return stocks' does not always hold, and regional leadership also rotates. The US led sharply over the past 15 years, but that is the outcome of one specific period and cannot be assumed to persist. Emerging markets carry high growth expectations but also currency, political, and liquidity risks that can make swings large and drawdowns deep. In the comparison calculator, review each market's ending balance together with its maximum drawdown and recovery period. The purpose is to understand both the meaning and the cost of country and regional diversification.
Open in comparison calculatorWhy this period and asset
Emerging markets (EEM) comprise stocks from high-growth-potential countries such as China, India, Taiwan, Korea, and Brazil. There has long been an assumption that 'high economic growth means high stock returns,' but the past 15 years told a different story. Over this period, US stocks rose strongly under Big Tech leadership, while emerging markets often lagged amid weak currencies, commodity cycles, and country-specific risks. It was a stretch showing that economic growth and stock returns do not always move together. In the earlier 2000s, however, there were periods when emerging markets outpaced 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, the US or emerging markets?
Neither is always better. The US led sharply over the past 15 years, but emerging markets led in earlier periods. Since regional leadership rotates, use the comparison calculator to view return and drawdown side by side.
How do the risks differ?
Emerging markets tend to have higher volatility and drawdowns from currency weakness and political and liquidity risk, while the US was comparatively stable. Concentration risk in particular countries also varies by index.
What should I use as the basis for comparison?
Look beyond the final return to maximum drawdown, time underwater, and recovery period. Bear in mind that economic growth and stock returns do not always move together.
