In the complex world of investing, the old adage 'don't put all your eggs in one basket' rings truer than ever. This is especially relevant for Canadian investors, who often find themselves grappling with a familiar yet persistent challenge: the lack of true global diversification in their portfolios. Despite the allure of domestic equities, which represent only a modest 3% of global markets, many Canadian portfolios allocate a staggering 50% to 60% of their assets to Canadian and U.S. holdings. This home-country bias, as Mr. Wong aptly describes it, is a significant risk factor that hasn't diminished but has merely shifted.
The rise of U.S. tech giants has inadvertently contributed to this phenomenon. While this shift has brought some natural diversification into U.S. markets, it's often concentrated in a handful of well-known companies. This new form of concentration risk is a double-edged sword. On one hand, it provides access to global innovation leaders, deep capital markets, and strong earnings growth. On the other, it ties portfolios to a narrow set of drivers, making them susceptible to market swings in those sectors.
The argument for global diversification is not just cyclical but structural. Canada's equity market is heavily skewed towards financials, energy, and materials, accounting for nearly 70% of the benchmark index. Conversely, sectors like technology, healthcare, and advanced manufacturing are underrepresented or absent, missing out on significant long-term growth opportunities. This imbalance highlights the need to look beyond North America to capture the full spectrum of global economic growth.
The recent market performance further underscores the need for global diversification. Developed markets have been outperforming since late 2024, while emerging markets have shown strength since early 2025. Historically, such shifts occur before portfolios adjust, indicating that investors are not yet fully diversified across the globe.
The good news is that achieving global diversification has never been more accessible. Investors can now tap into international markets through various vehicles, including American Depositary Receipts (ADRs), Canadian Depositary Receipts (CDRs), and a vast array of Exchange-Traded Funds (ETFs). ETFs, in particular, offer broad coverage of regions and sectors, democratizing access to global markets.
However, this expanded access also introduces new complexities. CDRs, for instance, provide exposure to foreign companies in Canadian dollars, reducing currency friction but potentially incurring hidden costs through spreads and fees. ADRs, while offering more efficient exposure, expose investors to currency fluctuations. The proliferation of options also carries the risk of over-diversification, where investors end up with overlapping exposures, diluting their conviction and leading to passive results.
Behavioural factors, such as familiarity bias, tax considerations, currency volatility, regulatory requirements, and geopolitical concerns, continue to hinder the transition to global diversification. Despite these hurdles, institutional investors like pension funds, endowments, and foundations have made significant strides in maintaining lower domestic allocations. For individual investors, the journey towards global diversification is slower but not impossible.
The key to successful global diversification is not just about investing globally but doing so with intention. Investors must avoid the temptation to chase recent market winners and instead build portfolios that are resilient across various outcomes. As Mr. Wong wisely notes, diversification is not about predicting the next outperform region but ensuring that your portfolio isn't overly dependent on any single macro driver or thesis. It's about striking a balance between risk and reward, cost and opportunity, to create a well-rounded investment strategy that can weather the ever-changing global market landscape.
