If you’ve been following this blog for a while, you’ll know that most of my wealth is in the stock market for the long-term. While there are many short term stock trading strategies, many of these strategies just don’t work out for regular investors. In fact, the initial losses often turn beginner investors away from the stock market altogether.
Data shows that over the long-term, the broad stock market goes up with an after-inflation return that is hard to beat. What does the broad stock market mean? It generally means that if you were to take all the biggest (and likely most profitable) companies in the world and owned them in a portfolio, the value would go up over the long-term (think 15+ years). Albeit, it may be a bumpy ride along the way (cough cough dot com bust, financial crisis, and the recent Covid-19 crash), but the market still goes up over longer periods – especially when you count dividends (see my article on Canadian Dividend Stocks).
It’s now easier than ever for investors to own a piece of the largest companies in the world through owning indexed investments – especially with the invention of All in one ETFs. I’ve written before about indexing the market and how it can be done through owning lower-fee mutual funds and better still, owning through even lower-cost index ETFs.
While indexing can be boring (set it and forget it), the growth over the long-term can actually be a little surprising even if returns appear mediocre. That’s thanks to the power of compounding returns. As an example of a 30-year-old who contributes $7,000/year (increasing contributions annually with inflation) to a retirement investment account that is indexed and assumed to return 4% after inflation. 4% may not seem like much, but after 35 years those $600/month contributions result in a $1M RRSP (assuming that tax refunds are re-invested).
As you can probably tell, I’m a fan of indexing and use the strategy for a number of my accounts like my kid’s education fund, and my spouses RRSP.
What is the Hot Potato Strategy?
So enough about regular indexing, what’s this Hot Potato Strategy? This strategy, founded by investment guru Norm Rothery, is essentially supercharging your index investment strategy by over-weighting the strongest performer (over the last 12 months) within your globally indexed portfolio. Mr. Rothery has shown that this strategy outperforms regular indexing over the long-term, but more on the performance in a little bit.
Let’s clarify this investment concept a little with an example.
In a diversified indexed portfolio, you’ll typically find the following portfolio (often called the couch potato portfolio) with various percentages of the holdings:
- Canada Index ETF/Mutual Fund
- US Index ETF/Mutual Fund
- MSCI International Index ETF/Mutual Fund
- Bond Index ETF/Mutual Fund
A typical portfolio for a young investor would be 25% of each of the positions and rebalance with new money and/or any time period that the investor wishes.
With the Hot Potato strategy, instead of spreading your money over four positions, you would concentrate your portfolio on a single position. Which position? The position that has performed the best over the past 12 months.
What about re-balancing? You can either re-balance once a year or once every month if you want to maximize performance.
As previously mentioned, the Hot Potato Strategy outperforms regular Couch Potato indexing over the long term. By how much?
According to Norm Rothery, from 1980 to Sept 2019, the strategy returned an annual average rate of 15.9% beating the Couch Potato strategy by 6.2% (9.7% return).
A 6.2% average annual return difference is massive. $1 invested returning 9.7% will give you $16.08 over 30 years. $1 invested returning 15.9% will give you $83.66, essentially a portfolio that is 5 times bigger.
If you are paying high fees for your portfolio management (or on a per trade basis) you should check out our list of best Canadian brokers that will save (big) money.
Now that you have a high-level understanding of the hot potato strategy, you may be interested in testing this out in your own portfolio – but how?
The strategy concentrates your portfolio on the best performer over the last 12-months. Mr. Rothery explains that you can compare the performance of the 4 holdings once a year, and hold that single position for the full year. For those of you a little more hands-on, rebalancing monthly has resulted in an even greater return.
So one key element of this strategy is finding a way of comparing performances. Luckily, investment performance is readily available on the web.
Here’s an example portfolio for a Canadian investor who prefers CAD ETFs:
- Canada Index ETF/Mutual Fund: XIU.TO
- US Index ETF/Mutual Fund: XUU.TO
- MSCI International Index ETF/Mutual Fund: XEF.TO
- Bond Index ETF/Mutual Fund: XBB.TO
One way to determine performance is simply going directly to the following sites, and look at the 1 year or 12-month trailing performance.
Personally, I like to use Big Charts and use the chart comparison tool over the past 12-months. As you can see from the charts below, I’ve compared XUU (US Index) with XIU.TO (Canadian index), XEF.TO (MSCI international index), and XBB.TO (Canadian bond index).
If you want to replicate, check out the images below and the settings that I used.
Big Charts – XUU.TO vs XIU.TO (XUU is the line chart) – XUU wins
Big Charts – XUU vs XEF.TO (XUU is the line chart) – XUU wins
Big Charts – XUU vs XBB.TO (XUU is the line chart) – XUU wins
As you can see from the chart, over the last 12-months, the US (XUU) handily beats the Canadian and MSCI International index, while the Canadian bond index came close.
So following this strategy, at this current time, a Hot Potato investor would be all-in the US Index.
So there you have it, a strategy for indexers than can help boost performance. For those of you interested in following this strategy, check out my instructions above on using Big Charts to comparing index performance to help choose the highest performing index over the past 12 months.
Personally, I would have a hard time concentrating my portfolio on a single index, but I can see how it could help add a little alpha to your portfolio by over-weighting a particular index.
If you are an indexer, what are your thoughts? Is this strategy a little too “active” for you?
