Loneranger, I count "cash" as savings, MM, or CDs.
Thanks for everyone's responses. I guess where I am at is taking 6 months cash and putting that in a seperate e-fund bucket that I don't count in my AA. But any cash beyond that I will count towards my retirement portfolio AA (unless, obviously, it is earmarked for something specific, e.g. car). If a dire emergency hit and I needed more than the 6 month e-fund (knock on wood...) that the cash is there to use, but I would need to rebalance the portfolio back to its target AA.
Thanks for all the insights, it was very helpful...
