I used to own one of those one-piece cutlery tools designed for hiking and camping—the kind with a knife, fork and spoon that all fold into a single unit. It was hardly ideal for eating, especially if you needed the fork and knife at the same time. But it was more convenient than trekking around with three individual pieces of flatware that might tear your pack or get left behind on the trail.
As investors we often make similar trade-offs. Consider the Vanguard FTSE Global All Cap ex Canada (VXC) or the iShares Core MSCI All Country World ex Canada (XAW), which both offer one-stop global diversification by holding thousands of US, international and emerging market stocks. But as with folding cutlery, you give up something to get that convenience. These two “ex Canada” funds get at least some of their exposure by holding underlying US-listed ETFs rather than holding their stocks directly. This structure can result in additional foreign withholding taxes on dividends.
