Why Investors Love Their Own Backyard (and Why That’s Not Always Smart)
When it comes to investing, we humans have a quirky habit: we love what feels familiar. This often means we invest heavily in the companies, industries, or markets of our own country, ignoring opportunities abroad. In finance, this tendency has a name—home bias.
Sounds harmless, right? After all, investing in your own country feels safe. But like many “safe” habits, home bias can quietly eat away at your potential returns and increase your risk in ways you might not realize. Today, let’s unpack what home bias is, why it happens, and how you can fight it.
What Is Home Bias?
Home bias refers to the tendency of investors to favor domestic stocks and bonds over international investments, even when global diversification might provide better returns or lower risk.
For example, a U.S. investor might hold 90% of their stock portfolio in U.S. companies, even though the U.S. represents only about 40% of the global stock market by capitalization. Similarly, a European investor might overweight European stocks while ignoring markets like the U.S., Asia, or emerging economies.
Why Do We Fall for Home Bias?
There’s no single reason. It’s a cocktail of psychology, comfort, and sometimes even laziness. Here are the main culprits:
1. Familiarity
We naturally trust what we know. If you recognize the name of a local bank or a national tech company, you feel safer investing in it compared to an unknown company in another country.
2. Information Advantage (or So We Think)
Investors often believe they have better information about domestic companies because they see them in the news or use their products daily. But the truth is, global markets are equally efficient, and local familiarity rarely translates into better insight.
3. Currency Fear
Some investors avoid foreign markets to dodge currency fluctuations. While it’s true that exchange rates can affect returns, currency risk can be managed—and often, it’s a small price to pay for global diversification.
4. Patriotism or Habit
Call it loyalty or inertia—investors sometimes prefer to support their home economy, or simply stick with what they’ve always done.
Why Is Home Bias a Problem?
Overloading your portfolio with domestic assets may feel safe, but it often means you’re missing out on better growth opportunities elsewhere. Here’s why home bias can hurt you:
- Lack of Diversification: If your home market tanks due to a recession or political instability, your entire portfolio suffers. Global markets don’t all move in sync, which is why diversification works like a safety net.
- Missed Opportunities: Emerging markets, for example, may offer higher growth than mature domestic markets. By ignoring them, you’re potentially leaving money on the table.
- Sector Overexposure: Some countries’ stock markets are overly concentrated in a few sectors. For example, Canada is heavy on energy and financials. If those sectors stumble, so does your portfolio.
A Simple Example
Imagine you live in Italy. You might own a basket of Italian companies—banks, fashion brands, maybe an energy company. But what happens if Italy’s economy slows down? You’ll be hit harder compared to someone with a global portfolio that also includes U.S. tech stocks, Asian industrial companies, and European healthcare giants.
Global diversification doesn’t mean chasing exotic assets; it just means spreading your risk so one country’s troubles don’t dominate your returns.
How to Overcome Home Bias
Breaking free from home bias doesn’t require a financial revolution. It’s about building a well-balanced portfolio that reflects the global economy. Here’s how:
- Use International ETFs or Index Funds: Funds tracking global indexes like the MSCI World or All-Country World Index give you exposure to hundreds of companies across multiple countries.
- Set Allocation Targets: Decide what percentage of your portfolio should be international—say 30%—and stick to it.
- Don’t Overthink Currency Risk: Over the long term, currency movements tend to balance out, especially when you’re diversified.
- Stay Informed, Not Obsessed: Read up on international markets the same way you follow domestic news. Familiarity will reduce your hesitation.
Final Thoughts
Home bias is like comfort food: it feels good but isn’t always the healthiest choice. By sticking to what’s close to home, you might miss out on the broader buffet of opportunities that global markets offer.
The solution isn’t to abandon your local investments, but to open the door to the rest of the world. A globally diversified portfolio can help you smooth out the bumps, seize growth where it’s happening, and ultimately become a more resilient investor.
So next time you look at your portfolio, ask yourself: Am I staying too close to home?
