Where ETFs are going is more important than where they have been. The above example illustrates a process that does not involve a rearview mirror.
A Case Study: iShares Canada
Too many firms use what is, in my opinion, the wrong approach to analyzing ETFs. A case in point is a recent research report from Morningstar about iShares Canada (EWC), called "Think Thrice Before Buying iShares MSCI Canada Index."
The report generally is negative, but it offers no forward-looking analysis. It opens with the fact that it is not a good idea to buy a fund coming off of years of outperformance. But this truth is better applied to smaller, open-end funds that have had a huge inflow of cash that has the potential to alter whatever method generated those attention-getting results.
iShares Canada and other single-country ETFs are index funds. How far down your list of important things to study before buying the ETF equivalent of a country is consideration of past performance? If you had read the Morningstar report, you might believe it should be the most important factor to consider, because it leads the report.The Morningstar report also warns about the 20% of the fund that is in energy stocks; actually, 28% of the fund is in energy stocks. I take the other side of that entirely: I want Canada to be a proxy for the energy sector. The U.S. imports a significant amount of its oil from its neighbor to the north. If you don't want the energy exposure, I would say there's no point in owning Canada. It makes sense to expect that whatever happens in Canada, good or bad, will be attributable to the oil market. The report also takes issue with the fact that the four top holdings each have a 5% weight in iShares Canada. If you look at the top holdings of some of the other single-country ETFs, you will see this is quite common. The reason for this is that some of these foreign markets have a lot fewer moving parts, so managers resort to weightings of 5% or more. While the point of single stock risk is valid, Morningstar's report makes it seem like this is unique to iShares Canada, which it is not. In fact, iShares Canada has relatively little concentration compared with other single-country ETFs such as iShares Sweden (EWD), which has 22% in Ericsson (ERICY), or iShares Belgium (EWK), which has 24% in Fortis.
