@michaelsblade700 In accounts where I have the ability, I do stick with total world ratios, at least rounded to the nearest multiple of 5 (and as long as they stay between 70/30 and 30/70).
@michaelsblade700 Exactly like VTWIX, since I use the Admiral share class, VTWAX, as my reference.
VTWIX is the institutional share class with an initial minimum in the millions, your 401K qualifies as a whole company, had this been say your IRA, VTWAX would be what you'd have to use instead.
