Hi AIMster,
That certainly is one way to do it!
You have the asset class, that has PC and all the other AIM goodies.
This asset class is measured by something liquid, cash.
The 'problem' here is that both classes are money.
I think for cash we should take the 'money' of the biggest economy, or where the amount of money is the biggest. Then the lighter economy would be the asset class. So US$ as cash and AU$ as asset class.
When we have 3 classes we want to AIM, take the liquid large asset class as money and then AIM the other 2 classes with it, with Lichello's portfolio model or with separate machines with combined or not combined cash.
Kind Regards, K
