Home country bias, the tendency to favor investments from your home country, is a common habit among investors worldwide. Could this bias be costing you money and adding unnecessary risk to your portfolio? For many Canadian investors (and even those in other G7 countries), the answer is yes. This blog post will explain what home country bias is, why it’s risky (especially in Canada’s market), and how diversifying internationally can improve your investment outcomes. We’ll also explore the behavioural reasons behind home bias and show how Diversification, Strategic Asset Allocation, Avoiding Excessive Risk, and Long-Term Unemotional Investing, help counteract this bias.

What Is Home Country Bias?
Home country bias is an investor’s preference to invest primarily in domestic assets (usually stocks) while underweighting foreign investments. In other words, it’s when you put most of your money in companies from your own country, ignoring the fact that there’s a whole world of investment opportunities out there. Home bias often leads investors to hold a majority of their portfolio in domestic equities, despite the benefits of global diversification.
This phenomenon is widespread across the globe, it’s not just Canadians. Americans, for example, invest roughly 85% of their stock portfolios in U.S. companies, even though the U.S. market makes up only about 60% of the global stock market.
In countries like Japan, the UK, Germany, and others, investors also exhibit a strong preference for local stocks.
In essence, many people feel safer investing in what they know (their home market) and shy away from foreign investments.
Why does home bias happen?
Historically, there were practical barriers to global investing, things like higher transaction costs, currency conversions, limited access to foreign markets, and less information about overseas companies.
These hurdles made it more difficult and costly to invest abroad, so sticking to domestic stocks was the default. There’s also a psychological comfort factor: we tend to trust what is familiar. This is sometimes called familiarity bias, we feel we understand local companies, brands, and economic conditions better than foreign ones, so we “stick to what we know”. Other behavioral factors include overconfidence and a perception that foreign markets are riskier or more opaque. In Canada, there’s even a bit of national pride at play, as one Vanguard Canada expert noted, Canadians have a “long-standing belief and pride” in investing close to home (wealthprofessional.ca).
Ironically, global investing has never been easier or cheaper. Online platforms and low-cost ETFs offer simple access to international markets, with a wealth of information readily available. Finally, international index funds and ETFs make global investing remarkably accessible.
Despite this, home bias persists, driven largely by habit and emotion rather than logical planning.
Canadian investors have historically shown one of the highest home biases in the world. The good news is this bias is slowly declining, but it’s still significant. Recent research by Vanguard Canada (2024) found that Canadian investors now allocate about 50% of their equity portfolio to domestic (Canadian) stocks. A decade ago, this figure was even higher, around 67% in 2012, so there’s been improvement.
This is striking when you consider that Canada makes up just 2.5–3.0% of the global stock market. That means Canadians are allocating 15–20 times more to local equities than Canada’s global share. Vanguard put it plainly: a 50% home bias equals “18 times more” exposure than justified by Canada’s weight in global indexes.

Picture the global market as a full pie, with Canada representing just a small slice. Yet many investors concentrate a large portion of their portfolios on that one piece—missing out on the other 97% of opportunities around the world.
It’s not just retail investors. As of late 2019, 54% of Canadian-domiciled ETF assets were in Canadian stocks, with just 24% in U.S. equities and ~20% globally.
This domestic focus has been prevalent, though it’s gradually shifting as advisors and investors recognize the need for global diversification.
While this domestic focus is shifting, it still lingers. Other G7 countries show home bias too, but with key differences. U.S. investors, for example, hold about 85% in domestic stocks, even though the U.S. makes up ~60% of global markets. But because the U.S. market is large and sector-diverse, its home bias carries less concentration risk than Canada’s smaller, more narrowly focused market (investopedia.com).
One of the biggest pitfalls of home country bias is "overconcentration": you end up with a portfolio that’s not well diversified because it’s heavily tilted to the fortunes of one country’s economy and a few dominant sectors. This risk is especially pronounced for Canada.
The Canadian stock market (represented by indexes like the S&P/TSX Composite) is highly concentrated in a few sectors. As of 2025, about 32% of the TSX index is in financial services (banks, insurance, etc.).
All together, roughly 62%+ of the Canadian equity market is tied up in just three sectors: financials, energy, and materials.
This concentration means if those sectors hit a slump, Canadian portfolios get hit hard.
Meanwhile, other sectors are underrepresented in Canada. For example, technology is only about 8% of the TSX by weight, and health care is a very small portion (Canada has few large pharma/biotech firms). Compare this to a global index like the MSCI World or MSCI All-Country World Index (ACWI): tech companies make up roughly 20–25% of global equities (msci.com), and other sectors like consumer goods, industrials, and healthcare each hold substantial weights. The U.S. market is home to global growth drivers like Apple, Microsoft, Amazon, and Google, none of which are captured in Canadian indices. European and Asian markets bring exposure to auto giants, luxury brands, telecoms, and hardware firms—opportunities Canadian-only portfolios miss out on.
The danger for Canadian investors with a strong home bias is that you end up with a less diversified portfolio that can be very volatile and dependent on commodity cycles and domestic economic conditions. For instance, if oil prices crash or the Canadian housing market faces trouble (impacting banks), a Canadian-heavy portfolio could drop significantly while more globally balanced portfolios might better withstand the shock. A report from Morningstar Canada noted that Canada’s narrow sector representation and small share of global market cap means Canadians especially benefit from “spreading one’s bets” across borders (indexes.morningstar.com).
Otherwise, you may be “putting all your eggs in one (small) basket”. See our What is Diversification article for more on that.
Home bias doesn’t just increase risk, it can also mean missing out on higher returns elsewhere, i.e. an opportunity cost. Over the past decade, Canadian equity investors who stuck mainly to Canada lagged far behind those who invested globally. A Morningstar analysis found that Canadian investors with significant home bias have missed out on substantial market gains in foreign markets, particularly U.S. equities, over the past decade.
Simply put, the 2010s saw U.S. and international stocks (especially tech-driven markets) dramatically outperform Canadian stocks. The S&P/TSX Composite’s returns were respectable, but they were eclipsed by the S&P 500’s returns. So a Canadian who stayed 100% at home earned a lot less than one who held some Apple, Google, or international growth stocks in their portfolio.
Even looking forward, no single country’s market is guaranteed to lead every year. Leadership rotates: one year U.S. stocks might surge, another year European or Asian markets might outperform, and sometimes Canadian stocks will be on top. If you’re globally diversified, you can capture the winners wherever they are. If you’re not, you could be stuck with a laggard market. In the words of an FTSE Russell strategist commenting on Canadian home bias: Canadian investors focusing only on Canada are “missing out on diversification” and the growth available in markets like the U.S. or even Europe.
The cure for home country bias is international diversification, spreading your investments across countries and regions, not just at home. Diversification is a core principle of sound investing for many reasons:
Another thing to realize: global investing doesn’t mean taking on “exotic” or unnecessary risk. We’re talking about investing in other developed markets (like the US, Europe, Japan) and perhaps some allocation to emerging markets, all of which are well-established investment arenas. Many of the world’s largest, most stable companies are outside Canada. By owning them, you’re not gambling; you’re arguably investing more prudently by not putting all your money in one economy.
A Vanguard Canada strategist said that while Canadians are (slowly) showing greater appetite for global equities, which is “positive”, the current level of home bias is still high and can lead to “sector concentration, greater volatility, and less efficiency”, contributing to higher risk.
The consensus among experts is clear: global diversification is beneficial.
If global investing is so clearly advantageous, why do many intelligent investors still lean heavily at home? The answer often lies in psychology and behavioral biases. Understanding these biases is the first step to overcoming them:
It’s worth noting that even professional investors are not immune to home bias. Studies have shown many fund managers and pension managers exhibit a preference for domestic assets, sometimes even a “local bias” (favouring companies headquartered in their province or state).
This is human nature at work.
Being aware of these psychological drivers is important. It helps us realize that home bias is often not a rational, deliberate choice based on data; rather, it’s a default that feels comfortable. Once we recognize this, we can take deliberate steps, grounded in facts and strategy, to counteract the bias.
SciVest’s investment philosophy centers on principles that directly address and correct for home country bias. Let’s look at how four of SciVest’s Core Investment Beliefs provide a framework that steers investors away from the dangers of home bias:
In summary, SciVest’s core beliefs act as a compass pointing away from home bias. By championing global diversification, deliberate asset allocation, risk control, and rational long-term behavior, these principles help investors avoid the pitfalls of over concentration in domestic markets. Investors who adopt such principles are far less likely to succumb to home country bias, and more likely to achieve stable, long-term growth.
If you suspect home bias might be lurking in your portfolio, don’t worry, you’re certainly not alone, and there are concrete steps you can take to correct it. Here are some practical strategies to overcome home bias and build a more globally diversified investment portfolio:
By implementing these steps, you can gradually mitigate home country bias and build a more resilient, globally balanced portfolio. The changes don’t have to be abrupt, you can shift allocation over time, or allocate new contributions more internationally until your mix is where you want it. The important thing is making that conscious effort. Your future self, enjoying retirement income that isn’t dependent on the fate of one country, will thank you.
Home country bias is a natural tendency, but as we’ve explored, it can carry hidden costs for investors. For Canadian investors in particular, an excessive focus on domestic equities means a less diversified portfolio, greater exposure to local economic swings, higher volatility, and missed opportunities for growth abroad. In an increasingly globalized world, limiting your investments to one small corner of the market just doesn’t stack the odds in your favour.
The antidote is clear: embrace international diversification. By spreading your investments across countries and sectors, you reduce risk and open the door to a world of growth potential. This isn’t just a theoretical stance, data and history back it up, and it aligns with core investment principles followed by seasoned professionals. SciVest’s beliefs in diversification, strategic asset allocation, risk management, and long-term discipline all reinforce the idea that a well-diversified global portfolio is key to long-term success.
The great news is that diversifying beyond Canada is easier now than ever. With a plethora of global funds, ETFs, and information at your fingertips, you can invest worldwide with the same ease as investing at home. Whether you’re a young RRSP investor just starting out, a high-net-worth individual managing a complex portfolio, or a DIY investor fine-tuning your TFSA, the guidance remains the same: check your home bias, and take steps to balance it out.
By recognizing the bias in yourself and using the practical strategies discussed, from global ETFs to regular rebalancing, you can ensure that home bias isn’t silently undermining your financial goals. Remember, it’s not about abandoning Canadian investments entirely; it’s about right-sizing them as one part of a broader, smarter investment plan.
So, is home country bias costing you money? It very well could be, but it doesn’t have to. With knowledge and action, you can turn a home-heavy portfolio into a well-traveled one. In doing so, you’ll be aligning your investments with the reality of the global economy and setting yourself up for a smoother ride toward your long-term financial destination.
Happy (global) investing!
