You'd be better off putting the money into FDIC insured CDs or savings accounts (with interest rates ~1%). That's said, through inertia and laziness I have too much of my portfolio in VMMXX.
Despite the convenience (all funds in one place), I finally gave up on VG altogether for cash holdings
and put it all in a) max allowable in iBonds, and b) the rest at Ally. Might as well get ~ 1% instead of ~ 0%...
