I'll call this highlight from the Motley Fool article the donut example. Pretty easy to understand. If you haven't moved your holdings out of US$, better hurry. It's getting ugly and it's only gonna get worse (thank you Ben Bernanke you fu*king traitor idiot)
For example, U.S.-based investors in Canadian doughnut slinger Tim Hortons (NYSE: THI) have profited mightily over the past year as the greenback swooned against the loonie. And guess what? With U.S. interest rates declining, chances are that the dollar will continue to be weak.
The difference is dramatic: U.S. shareholders have seen Tim Hortons rise from US$25.15 to its current price of US$34.14. Canadian investors have seen the price go from CAD$28.00 to CAD$34.59.
In Canada, Tim Hortons shareholders have gained 24%. For U.S-based investors it was 36%. The difference? The dollar's slide.
Now, I'm not saying that the dollar will continue to go down. What I am saying is that investors who diversify away from their home currency do themselves a huge favor by looking overseas for investments. I'm also saying that a lower interest rate environment in the United States suggests that the trend isn't changing.
