Hello lovethetrade, no they are not necessary and at one point I was balancing across Eur/gbp, Eur/Jpy, Eur/usd, Gbp/Jpy, Gbp/usd and Usd/jpy only. The problem with that was I was consolidated across less pairs. It's not perfect now, but I believe better, even though it can be slightly weighted into Usd or Eur more than the others. In an environment where the average person has zero hedge and fully weighted into their country of origin, I believe it is better.I really like how balanced that FX portfolio is, it's obvious you know what you're doing. Are the CHF crosses necessary though because it's highly correlated (approx. 95%) with the Euro?
Thanks for the question.
