This page compares 15 years of steady monthly investing into a KOSPI 200 ETF (069500) and an S&P 500 ETF (SPY), using the comparison calculator. It looks at the data behind the 'Korea vs US market' debate and the limit of not reflecting the exchange rate.

Method · Comparison

The key is that the two markets differ in character and that the basis of comparison must be clear. In particular, results can change depending on whether the two assets are viewed in a common currency or each in its own. US assets' returns in Korean won shift with the won-dollar exchange rate, so you must check whether the exchange rate is reflected. In the comparison calculator, review each market's ending balance together with its maximum drawdown and recovery period. Rather than simply which return was higher, understanding market character and the currency/exchange-rate basis matters.

Why this period and asset

The KOSPI 200 is an index of Korea's 200 leading companies, heavily weighted toward export manufacturing such as semiconductors, autos, and batteries. Over the past 15 years, the KOSPI went through repeated range-bound stretches, while the US S&P 500 trended steadily upward in many stretches under Big Tech leadership. That pattern became the backdrop for the 'leave the Korean market for the US market' debate. The KOSPI, however, also showed strong rallies in certain stretches (e.g., the 2020-2021 rebound) and has reacted sensitively to the economic and export cycle.

Caveats & limits

This comparison reflects one specific past period, and which side leads can change with the start or end date. In particular, US assets' won-converted results shift greatly depending on whether the exchange rate is reflected, so confirm the calculation basis. Past performance does not guarantee the future. In real investing, fees, taxes, and exchange rates affect outcomes. This page recommends no purchase; it is educational material comparing character.

Frequently asked questions

Which is better, Korea or the US?

Neither is always better. The US led steadily in many stretches over the past 15 years, but the KOSPI also rose strongly in certain stretches. Use the comparison calculator to view return and drawdown side by side while checking the exchange-rate basis.

How do the risks differ?

The KOSPI is sensitive to the export and economic cycle and was often range-bound, while the US was comparatively steady. US assets, however, add exchange-rate risk, so viewed in Korean won the swings differ.

What should I use as the basis for comparison?

Look beyond the final return to maximum drawdown, time underwater, recovery period, and be sure to confirm whether the won-dollar exchange rate is reflected. A different currency basis changes the outcome even for the same asset.
