Re: Is your grandmother still participating?
If your grandmother is still involved in managing her finances, and if she's still sleeping at night (or at least doesn't care) then there's no reason to mess with it. If she's nervous or if she wants to try out what she just read in "Four Pillars" then maybe it's worth altering the mix.
There are more opinions than posters on this board, but it seems that she has a decent allocation with an incredibly low withdrawal rate. I don't believe that portfolios should move to bonds with rising age. There's a tremendous amount of wiggle room in her portfolio but no NEED to change anything.
So unless she's itching for a change then she probably don't need to mess with success. I say this because at her age she could change the portfolio a lot and still be close to a 100% success rate.
After all, if the whole portfolio blows up, you'll assume the responsibility for her care & feeding, right?
