What Is International Equity?
International equity refers to ownership stakes in companies headquartered outside an investor's home country. It represents a fundamental component of diversification within a broader investment strategy, falling under the domain of portfolio theory. By allocating a portion of an investment portfolio to international equity, investors aim to tap into growth opportunities and mitigate risks that may be specific to their domestic market. International equity can include stocks from both developed markets, such as Europe and Japan, and emerging markets, like China, India, or Brazil. This strategy moves beyond purely domestic investments to embrace the global economic landscape, providing exposure to different industries, economic cycles, and regulatory environments.
History and Origin
The concept of international investing, including in equities, has roots dating back centuries, with early forms of cross-border capital flows financing trade and colonial expansion. However, the true "globalization" of financial markets, enabling more widespread international equity investments, gained significant traction in specific periods. Before World War I, around 1815 to 1914, there was a period of expanding equity markets and significant globalization, allowing capital to flow more freely across borders to optimize returns. This era saw capital move extensively from core European countries to regions of recent settlement, often into government bonds and infrastructure like railroads.11
After a period of contraction due to the World Wars and government controls, financial markets began to re-globalize in the latter half of the 20th century. Factors such as advances in information technology, the liberalization of national financial markets, and the increasing globalization of real economic activity (e.g., multinational companies) spurred an explosive increase in the speed, size, and scope of international money transactions.10 This resurgence, particularly from the 1980s onwards, led to a renewed focus on international equity as a means for investors to participate in diverse global economies.
Key Takeaways
- International equity involves investing in companies located outside an investor's home country.
- It offers potential benefits such as enhanced growth opportunities and risk mitigation through geographic diversification.
- Investors can gain exposure to international equity through various vehicles, including individual stocks, mutual funds, and Exchange-Traded Funds.
- Key considerations for international equity include currency risk, political instability, and differing regulatory environments.
- Despite periods of muted performance, international equity can contribute to a more resilient and globally diversified asset allocation.
Formula and Calculation
International equity is not typically defined by a single formula for its calculation, as it represents a category of assets rather than a specific financial metric. However, its contribution to a portfolio's overall performance and risk can be analyzed using standard portfolio management formulas.
For example, the weight of international equity within a total portfolio is calculated as:
When evaluating the impact of international equity on overall portfolio volatility or risk-adjusted return, concepts like standard deviation and Sharpe Ratio are used, which incorporate the performance and correlation of international equity assets with other assets in the portfolio.
Interpreting International Equity
Interpreting international equity involves understanding its role within a broader investment portfolio management context. For many investors, the primary motivation for including international equity is to achieve diversification benefits that a purely domestic portfolio cannot offer. This means spreading investment risk across different economies and political systems, potentially reducing the overall portfolio volatility. For example, if a domestic economy is experiencing a downturn, strong performance in international markets might help offset those losses.
Furthermore, international equity provides access to industries or growth narratives that may be underrepresented or unavailable in the home market. For instance, an investor seeking exposure to certain natural resources or rapidly expanding consumer bases in emerging economies would turn to international equity. The performance of these investments should be viewed not in isolation, but in how they interact with domestic holdings and contribute to the portfolio's overall asset allocation and return objectives.
Hypothetical Example
Consider an investor, Maria, based in the United States, who initially has a portfolio consisting entirely of U.S. stocks and bonds. Her total portfolio value is $100,000. Recognizing the benefits of global diversification, Maria decides to allocate 25% of her equity portfolio to international equity.
She has $70,000 invested in U.S. equities and $30,000 in U.S. bonds. She rebalances her portfolio by selling $17,500 of her U.S. equities (25% of $70,000) and invests it into an international equity Exchange-Traded Fund (ETF) that tracks a broad index of non-U.S. developed and emerging market stocks.
After this adjustment, Maria's portfolio now looks like this:
- U.S. Equity: $52,500
- International Equity: $17,500
- U.S. Bonds: $30,000
- Total Portfolio: $100,000
Suppose over the next year, the U.S. stock market declines by 10%, but the international equity market, primarily driven by strong performance in Asian emerging markets, increases by 15%.
- U.S. Equity value: $52,500 * (1 - 0.10) = $47,250
- International Equity value: $17,500 * (1 + 0.15) = $20,125
- U.S. Bonds remain stable at $30,000 (for simplicity).
Maria's new total portfolio value is $47,250 + $20,125 + $30,000 = $97,375.
Without the international equity exposure, her portfolio would have been $70,000 * (1 - 0.10) + $30,000 = $63,000 + $30,000 = $93,000.
In this hypothetical scenario, the international equity allocation helped mitigate the downturn in her domestic market, leading to a better overall portfolio outcome.
Practical Applications
International equity plays a crucial role in modern portfolio management and investment planning. One of its primary applications is enhancing portfolio diversification. By investing in companies across various countries and economic cycles, investors can reduce the impact of a downturn in any single domestic market. This geographical spread helps to mitigate specific regional risks and can lead to a more stable portfolio over time.9
Another key application is accessing growth potential beyond domestic borders. Many developing economies offer higher growth rates than mature markets, and international equity allows investors to participate in these opportunities. For example, some non-U.S. markets may offer more attractive valuations, and shifts in currency values can also benefit foreign-stock investors when gains are translated back into their home currency.8
Furthermore, international equity is vital for aligning an investment portfolio with global market capitalization. A global market-cap-weighted portfolio typically allocates a significant portion to international stocks (e.g., approximately 40% of a total world stock index for non-U.S. stocks), reflecting the actual size and influence of companies worldwide.7 Investors can gain exposure to international equity through diverse investment vehicles, including individual foreign stocks, country-specific or regional Exchange-Traded Funds, and globally diversified mutual funds.
Limitations and Criticisms
While international equity offers significant benefits for diversification, it also comes with certain limitations and criticisms. A primary concern is currency risk. For an investor holding foreign assets, fluctuations in exchange rates between their home currency and the foreign currency can impact returns. If the foreign currency weakens against the investor's home currency, it can erode gains, even if the underlying international equity performs well.6 This risk can be particularly pronounced and has been a factor in periods where the U.S. dollar strengthened significantly against major foreign currencies.5 While hedging strategies can mitigate currency risk, they often incur additional costs.4
Another limitation is increased volatility and complexity. International markets, particularly emerging markets, can exhibit higher levels of price swings due to political instability, regulatory changes, or less developed financial infrastructures.3 The correlation between U.S. and non-U.S. markets has also increased over time, particularly for developed markets, which can sometimes mute the diversification benefits.2 Additionally, investing internationally may involve higher transaction costs, different tax implications, and less transparent financial reporting compared to domestic markets. The International Monetary Fund (IMF) regularly assesses global financial stability, noting that while capital flows can bring benefits, they also introduce vulnerabilities, especially in emerging and frontier economies, due to factors like debt levels and market volatility.1
International Equity vs. Global Equity
The terms international equity and global equity are often used interchangeably, but they have a subtle yet important distinction from a portfolio construction perspective.
International equity specifically refers to investments in companies located outside the investor's home country. For example, for a U.S.-based investor, international equity would include stocks from companies in Europe, Asia, Latin America, and other non-U.S. regions. The focus is exclusively on non-domestic markets.
Global equity, on the other hand, encompasses investments in companies worldwide, including both domestic (home country) and international equities. A global equity fund or portfolio aims to cover the entire investable universe of stocks across all countries. For a U.S. investor, a global equity fund would hold a combination of U.S. stocks and non-U.S. stocks, often weighted by market capitalization to reflect the global stock market.
The key difference lies in scope: international equity is a subset of global equity, focusing only on the non-domestic component. A portfolio solely focused on international equity would lack domestic exposure, whereas a global equity portfolio provides comprehensive worldwide coverage.
