I have one master portfolio with several sub-portfolios. The master portfolio includes stocks from different accounts including IRAs and a regular brokerage account. The sub-portfolios are grouped by investment types, not by investment accounts. (For instance, one sub-portfolio might contain only stocks recommended by a particular advisory service, but those stocks may exist is several accounts.) My confusion is how to arrange default cash accounts, since money cannot be interchanged between accounts, but quite often will pass between sub-portfolios. This creates a problem in calculating the yield on a particular sub-portfolio.
Can you help me figure this out, other than manually tracking the cash.
