Hi Cap, I appreciate your thoughts. The long dead zone in currency ETF prices from around 2011 thru 2015 is what killed my enthusiasm.
Many moons ago when I was still selling capital equipment, sometimes overseas, the interest in ex-US currencies first arose. It was a way to help secure profits on 2-4 year projects. Currency exchange drift could eat all the profits in long contracts, so we hedged. That was before ETFs were invented, however.
When the currency ETFs made their debut I thought they might be a clever way to balance risk in investing in ex-US ETFs. The thought was similar to when I'd been in capital equipment - to protect profits in long term foreign investments from currency valuation drift.
Again, thanks for your experience and thoughts on the subject.
