Canada consistently ranks among the countries with the best quality of life, earning high marks for our standard of living, life expectancy, education system and environment among other dimensions of well-being.
We can be justifiably proud of the quality of life we enjoy here and it’s no doubt the reason why people from the around the world are lining up to move to Canada. However, when it comes to your investments, too much Canada is a bad thing.
A recent report from Vanguard notes that while Canadian stocks represent just 3.4% of the global equities market, Canadian investors allocate 52.2% of the equity portion of their portfolio to Canadian stocks.
This 15-to-1 mismatch is the result of the well-know phenomenon of home bias. Canada is far from the only country where investors prefer domestic holdings over foreign ones. The Vanguard report shows its even more pronounced in such countries as Australia, Japan and the Euro area.
There are several reasons why an investor might prefer to buy domestic stocks, but it usually comes down to simple familiarity. The companies that make up your local stock market, you hear about in the news daily.
While understandable, home bias is nevertheless a serious impediment to portfolio diversification, which is the key to reducing risk. This is very much the case in Canada, where a handful of companies and just three sectors dominate the equity market.
Vanguard reports that the top 10 holdings in Canada represent nearly 37% of the Canadian stock index. By contrast, the top 10 holdings make up 16% of the global stock market. When it comes to sector concentration, Canada is heavily overweighted in financial services (+16.4%), energy (+12.1%) and materials (+7.2%) as compared to the global market, and underweighted in information technology (-13.0%), health care (-11.7%) and consumer discretionary (-7.3%).
As a result, the Canadian market has historically been more volatile than the global market without a proportionate increase in return. That’s a bad deal for investors and the obvious reason why you would want to add a substantial quantity of global stocks to your portfolio mix.
Look no further than Canada’s big pension funds to see how the most sophisticated investors allocate the money they manage globally.
CPP Investments, which manages the $570-billion Canadian Pension Plan Fund, doesn’t disclose the geographical distribution of its $135-billion public equity portfolio. However, as of March 31, only 14% of its total net assets were in Canada. The Caisse de dépôt et placement du Québec, manager of the Quebec Pension Plan, had 21% of its public market equities portion of it $402 billion in net assets invested in Canada at the end of 2022.
Modern portfolio theory dictates that the broadest possible diversification will be the most efficient for reducing risk. Therefore, in theory, your portfolio would replicate the geographic weightings of the global stock market.
However, even if that were possible, we’re living in Canada and there are solid reasons for holding more than 3.4% of your stock portfolio in Canadian assets, besides a simple preference for doing so. Notably, you’re exposed to foreign exchange risk when you convert proceeds from the sale of foreign assets back into Canadian dollars.
The Vanguard paper shows that the reduction in portfolio volatility declines as the allocation to international equities increases up to 70% and then begins to taper off gradually. The paper concludes: “Looking at the data, the optimal asset allocation for Canadian investors is a 30% allocation to Canadian equities and a 70% allocation to international equities because it has been shown to minimize the long-term volatility of their portfolio.”
Our equity model portfolio devotes 20% to Canada, 50% to the U.S. market and 30% to international markets which includes emerging markets. If we remove our home bias of 20% to Canada, the remaining 80% is invested to reflect roughly the global market cap-weights.
According to our market statistics, the U.S. stock market has outperformed Canadian and international stocks in every time period stretching back for 30 years. But the outstanding performance of the U.S. market goes back much further than that.
The Credit Suisse Global Investment Returns Yearbook analyzes a database of global markets dating back to 1900. The 2022 edition (which we discussed in our Capital Topics Podcast episode 38) looks back over the international investing boom that started in the mid-1970s and asks: “Should U.S. investors have gone global?”
The Yearbook looked at four separate periods between 1974 and 2021 and found the U.S. market beat global investments in each of the four periods by a substantial margin. In other words, a U.S. equity investor, in hindsight, would have been better off foregoing international diversification and sticking with the U.S. market.
This was true not only because the returns from the U.S. market were exceptional over the period, beating non-U.S. stocks by 1.9% per year, but because it was one of the least volatile markets in the world “as its size, scope and breadth ensured that it was highly diversified.”
This historic record should give Canadian investors food for thought as they decide how best to avoid the negative effects of home bias in their portfolio. However, you should be mindful not to base your investment decisions solely on past performance.
