Yep, I had another post a few months back where I talked about a US contraction (and Russia/Ukraine growth) through a different set of stats (but for the same business) I have more than one canary in the coal mine!
CAD hasn't done great in the last few weeks, so I wouldn't recommend that either. Keep in mind that in addition to the U.S. tie it's also got somewhat of an oil tie. Becoming a forex trader, which is what you'd be doing at this point, may be a good idea. But it also may be adding another moving part, one you may not know much about and one which is also at an inflection point, at a time when you've got a lot of other things going on?
