International Portfolio

  • The Bottom Line: An international portfolio is simply owning great businesses regardless of their zip code, reducing your reliance on a single country's economy and vastly expanding your investment opportunities.
  • Key Takeaways:
  • What it is: A collection of investments, typically stocks and bonds, in companies headquartered outside of your own country.
  • Why it matters: It is a powerful tool for genuine diversification, helping you avoid the dangerous psychological trap of home_country_bias and granting you access to a wider universe of potentially undervalued companies.
  • How to use it: By either carefully selecting individual foreign companies that fall within your circle_of_competence or, more commonly, by investing in low-cost, broad-based international index funds or ETFs.

Imagine you're the owner of a world-class restaurant. To create the best dishes, would you only buy ingredients from your local town's farmer's market? Of course not. You'd source the finest pasta from Italy, the richest chocolate from Switzerland, the most robust coffee from Colombia, and the sharpest cheese from England. Sourcing globally makes your menu more resilient (a local drought won't shut you down) and infinitely more interesting and high-quality. An international portfolio applies this exact same logic to your investments. It's a portfolio that deliberately includes stocks, bonds, or other assets from companies and governments outside of your home country. For an American investor, this means owning shares in a German automaker, a Japanese electronics giant, or a Brazilian mining company. For a European investor, it could mean owning a piece of an American tech company or a Canadian bank. At its core, it’s a recognition that wonderful, durable, and profitable businesses—the kind a value investor dreams of—exist all over the world. Limiting yourself to just one country is like being that chef who refuses to look beyond their local market. You might do okay for a while, but you're missing out on a world of opportunity and exposing yourself to unnecessary, concentrated risk.

“The best opportunities are found in the countries of maximum pessimism.” - Sir John Templeton

For a disciplined value investor, building an international portfolio isn't about chasing exotic, high-growth trends. It's about a relentless, logical application of core value principles on a global scale.

  • A Dramatically Wider “Shopping Aisle”: The U.S. stock market, while large, represents less than half of the world's total stock market value. By ignoring international markets, you are willingly ignoring over 50% of the potential “merchandise.” A value investor is a bargain hunter. Why would you voluntarily limit your search to just one wing of the global supermarket? The more companies you can analyze, the higher the probability you'll find a truly wonderful business trading at a fair price.
  • Finding the World's Best Economic Moats: Some of the widest and most durable economic moats belong to non-U.S. companies. Think of Nestlé's (Switzerland) global brand portfolio, LVMH's (France) collection of luxury goods, or Toyota's (Japan) legendary manufacturing prowess. A true value investor seeks to own these “castles” with protective moats, and many of the world's greatest castles are located abroad.
  • A Macro-Level Margin_of_Safety: Benjamin Graham taught us to demand a margin of safety when buying an individual stock—paying a price significantly below its estimated intrinsic_value. Geographic diversification is a form of margin of safety for your entire portfolio. No single country is immune to prolonged economic stagnation (ask Japan about its “Lost Decade”), political turmoil, or currency devaluation. By spreading your assets across different economies, you build a buffer that protects your long-term capital from the inevitable troubles that might befall your home country.
  • Exploiting Market Inefficiencies: While the U.S. market is heavily analyzed, many foreign markets are less so. This can lead to greater inefficiencies and, for the diligent analyst, more opportunities to find mispriced securities. The principles of Mr. Market, who swings from euphoria to despair, are universal. An international portfolio allows you to take advantage of his mood swings in multiple locations.

Building an international portfolio doesn't mean you need to become an expert on every country's politics and economy. It's about applying a sound, systematic approach.

The Method

There are two primary paths for adding international exposure to your portfolio.

  1. 1. The Direct Ownership Path (The Expert's Route):
    • This involves buying shares of individual foreign companies directly, such as purchasing Siemens AG on the German stock exchange.
    • Pros: Gives you ultimate control over the specific businesses you own.
    • Cons: This is the most difficult path. It requires a significant expansion of your circle_of_competence. You must be comfortable analyzing financial statements prepared under different accounting standards (IFRS vs. U.S. GAAP), understanding different regulatory environments, and dealing with currency_risk and potentially complex tax implications. This path is only for dedicated, experienced investors.
  2. 2. The Fund/ETF Path (The Prudent Route for Most):
    • This involves buying a mutual fund or Exchange-Traded Fund (ETF) that holds a broad basket of international stocks.
    • How to Choose:
      • Look for Broad Diversification: A good starting point is a fund that tracks a major global index, excluding your home country. For a U.S. investor, examples include the Vanguard FTSE All-World ex-US ETF (VXUS) or the iShares Core MSCI EAFE ETF (IEFA), which covers developed markets.
      • Focus on Low Costs: As with any fund, the expense_ratio is a critical factor. It's a direct drag on your returns. Look for funds with expense ratios well below 0.20%.
      • Decide on Developed vs. Emerging Markets: Some funds focus on stable, developed economies (like Europe and Japan), while others focus on higher-growth but more volatile emerging markets (like China, India, and Brazil). Many broad international funds hold a mix of both.

Evaluating the Approach

The most important question is: How much of my portfolio should be international? There's no single magic number, but here's a value-oriented framework:

  • Acknowledge Home Country Bias: Most investors have a massive bias towards their home country. A U.S. investor might have 95% of their stocks in U.S. companies. Acknowledge that this is an emotional, not a rational, allocation.
  • Start with a Baseline: A reasonable starting point for many is to allocate between 20% and 40% of their stock portfolio to international equities.
  • Consider Global Market Cap: A purely rational, market-cap-weighted approach would suggest an allocation closer to 50% international, mirroring the global market itself.
  • Don't Sacrifice Quality for Geography: The golden rule remains: It is far better to own a wonderful company in your home country than a mediocre company abroad. Never buy a foreign stock or fund just to “check a box.” The goal is to own great businesses at fair prices, wherever they may be.

Let's compare two hypothetical U.S.-based investors, Patriot Pete and Global Grace, each with a $500,000 stock portfolio. Patriot Pete believes in “investing in what you know,” which to him means only U.S. companies. His portfolio is 100% domestic. Global Grace believes in owning the best businesses, regardless of location. She allocates 70% of her portfolio to U.S. stocks and 30% to international stocks via a low-cost ETF. Here's how their situations might differ:

Scenario Patriot Pete's Portfolio (100% U.S.) Global Grace's Portfolio (70% U.S. / 30% Intl.)
A strong decade for the S&P 500. Pete's portfolio likely outperforms slightly, as it is 100% exposed to the hot market. Grace's portfolio performs very well, though it might lag Pete's slightly due to diversification.
The U.S. enters a “lost decade” of flat growth, but European and Asian markets perform well. Pete's portfolio stagnates. He feels frustrated and questions his entire strategy. The international portion of Grace's portfolio buoys her returns, providing growth while her U.S. holdings are flat. Her overall portfolio value holds up much better.
The U.S. dollar weakens significantly against other major currencies. The value of Pete's portfolio in global purchasing power terms declines. A vacation to Europe suddenly becomes much more expensive. The value of Grace's international holdings increases when converted back to U.S. dollars. This currency_risk hedge protects her global purchasing power.
A major U.S.-specific political or regulatory crisis occurs. Pete's portfolio is fully exposed and takes a significant hit. Grace's portfolio is buffered. The 30% invested in companies operating under different political and regulatory systems provides a crucial layer of risk_management.

Grace's approach isn't about predicting which country will do best next year. It's about building a more robust, resilient portfolio that is prepared for a wider range of economic futures. It is the classic value investor's approach: prepare, don't predict.

  • Superior Diversification: Reduces your portfolio's dependence on the health of a single economy, currency, and political system.
  • Expanded Opportunity Set: Gives you access to thousands of additional companies, increasing your chances of finding an undervalued gem.
  • Potential for Higher Returns: Allows you to invest in regions or countries that may be growing faster or are more undervalued than your home market.
  • Risk Reduction: Can lower overall portfolio volatility over the long term, as different markets don't always move in perfect lockstep.
  • Currency Risk: Fluctuations in exchange rates can impact your returns. A great stock can have its gains erased by an unfavorable currency swing when you convert the value back to your home currency. 1)
  • Political and Economic Instability: Investing in some countries, particularly emerging markets, carries the risk of political upheaval, expropriation, or economic mismanagement. This is why broad diversification through a fund is often safer than picking one or two stocks in a risky region.
  • “Diworsification”: The biggest pitfall is sacrificing business quality for the sake of geographic diversity. Buying a poorly run, overvalued company just because it's foreign is a terrible mistake. The principles of fundamental_analysis and insisting on quality are non-negotiable.
  • Complexity and Costs: Direct international investing can be complex due to different accounting standards, taxes, and trading costs. Even with ETFs, be mindful of expense ratios, as international funds can sometimes be slightly more expensive than their domestic counterparts.

For long-term investors, these effects often balance out over time, but they can cause significant short-term volatility.
