The rate of change is what will swing eps short term. If there was a rapid USD decline then margins would be compressed short term because it takes time for consumers to adjust to retail prices. A falling USD by axiom means the US standard of living (purchasing power) is declining.
The compensation hedge for NTZ is its China/Yuan/USD pegged manufacturing of low end product. Sales of EURO cost high end product would likely decline in the US market but the growth in USD/Yuan cost low end product may well accelerate even faster in the US market than the present 20% p.a. as it would have more price/point 'space' in the market.
The US is 30% of world GDP, NOT more or less. If you are a global company you always have these issues. It's better being exposed to a 30% Fx effect than a 0% effect (your not global) or a 100% effect (your only domestic), that's business.
What's more important is paying a cheap price for the company especially given most global companies are exposed to the same Fx possibility.
If you have a long time horizon most of these issues become insignificant. It took 40 years for NTZ to become the world leader with @ 10% market share. What's the problem holding them for 10+ years and watching them grow to 20% market share.
