Introduction: In the ever-evolving world of investing, the debate between international and US stocks has been a topic of interest for investors worldwide. Over time, both have shown remarkable growth, but which one has performed better? This article delves into a comprehensive analysis of international vs. US stocks over time, providing valuable insights for investors looking to diversify their portfolios.
Understanding the Difference
International stocks refer to shares of companies based outside the United States, while US stocks are those of companies listed on American exchanges. Both have their own set of advantages and disadvantages, making it crucial for investors to understand the differences between them.

Performance Over Time
To analyze the performance of international vs. US stocks over time, we'll look at key historical data points.
The 2000s: During the 2000s, the US stock market faced significant challenges, including the dot-com bubble burst and the 2008 financial crisis. However, US stocks managed to recover and even outperform international stocks during this period. The S&P 500, a widely followed index representing the top 500 companies in the US, saw a return of over 100% between 2002 and 2009, while international stocks struggled to keep pace.
The 2010s: The 2010s were a period of strong growth for both international and US stocks. While the US market continued to perform well, international stocks outperformed during this decade. The MSCI World Index, which tracks a basket of international stocks, saw a return of nearly 60% between 2010 and 2019, compared to a return of just over 30% for the S&P 500.
The 2020s: The 2020s have been marked by a global pandemic, which has caused significant volatility in both international and US stock markets. However, US stocks have once again outperformed international stocks. As of the end of 2021, the S&P 500 had seen a return of over 20%, while the MSCI World Index had only seen a return of around 10%.
Risk and Return
One of the key factors to consider when comparing international vs. US stocks is risk and return. Historically, international stocks have offered higher returns, but with higher risk. This is due to the fact that international markets are often more volatile and can be influenced by political and economic factors outside of the United States.
Diversification
Investors looking to diversify their portfolios often turn to both international and US stocks. By investing in a mix of both, investors can reduce their exposure to any single market and potentially increase their overall returns.
Conclusion
In conclusion, the performance of international vs. US stocks over time has been a topic of debate among investors. While both have shown remarkable growth, the choice between them ultimately depends on the individual investor's risk tolerance and investment goals. By understanding the differences between international and US stocks, investors can make informed decisions to build a well-diversified portfolio.
