In my last blog post, we worked out the approximate asset class weights for US, international and emerging markets stocks targeted by the iShare Core MSCI All Country World ex Canada Index ETF (XAW). Now that we’ve got our breath back and our allocations in order, let’s sharpen our scissors and start running through what it would take to slice up a 3-ETF portfolio holding a single global XAW fund into a 5-ETF portfolio holding the same positions in individual ETFs.

For example, a balanced 3-ETF portfolio (such as 20% Canadian stocks, 40% global stocks and 40% Canadian bonds) could be recreated into a 5-ETF portfolio by multiplying the 40% global stock target asset allocation by each of the US, international and emerging markets stock allocation weights that we calculated in our previous blog. This would lead us to invest 21.37% of the portfolio in US stocks, 13.89% in international stocks and 4.74% in emerging markets stocks.

Money Makes the World’s ETFs Go Round

Do you remember why in the world we’d want to create a more complicated handful of holdings out of your simple three-part portfolio to begin with? The simple answer: money. In an RRSP account, there can be noticeable foreign withholding tax and product cost savings to be had by breaking up with your global stock ETF. The larger your portfolio, and the higher your allocation to global stocks, the greater the potential savings.


By moving to a 5-ETF portfolio, you can potentially save $100s if not $1,000s per year.


Have I got your attention? Now to the logistics.


Breaking Up for Fun and Profit

Here are what the allocations described above look like in table form:

So if you were managing a $100,000 balanced portfolio, you would allocate $20,000 to a Canadian equity ETF ($100,000 × 20%), $21,370 to a US equity ETF ($100,000 × 21.37%), $13,890 to an international equity ETF ($100,000 × 13.89%), $4,740 to an emerging markets ETF ($100,000 × 4.74%) and $40,000 to a Canadian bond ETF ($100,000 × 40%).

Intentionally Familiar Turf

I’ve included the portfolio weights for other asset allocations below (as of September 30, 2017). If you’ve already noticed that these portfolios closely resemble my 5-ETF model portfolios, give yourself a gold star, because this is no coincidence. My model portfolios are meant to approximate these asset mixes, albeit with fewer decimal points to clutter the view.

The Not-So-Fine Print

There’s a catch, of course. Isn’t there always? To score the cost savings that make the exercise worthwhile, you will need to purchase US-listed ETFs in your RRSP account. This requires mastering the Norbert’s gambit strategy for converting your loonies to dollars as cheaply as possible. (I’ve posted step-by-step Norbert’s gambit YouTube tutorials to help with this task.)

If you feel intimidated by the process and would rather stick with your easier 3-ETF portfolio, that’s certainly your call. But before you dismiss the idea entirely, remember: The savings can be as much as the management expense ratio (MER) you’re already paying each year. For example, a balanced 3-ETF portfolio has an MER of 0.14%. The foreign withholding tax and product cost savings of a 5-ETF portfolio in an RRSP account is also about 0.14%. Are you sure you want to leave that much money behind?

To help you decide, check out the table below, showing estimated tax and cost savings for a 5-ETF portfolio. If you have less than $50,000 in your RRSP account, a very conservative asset allocation, or both, you may decide the potential savings – about the cost of a modest meal – just isn’t worth the extra complexity. At the other end of the spectrum, if you can feast on major money spared, you may want to go for the gusto.
