Okay, this has been bugging me for a while, and I just need some feedback. I am a Boglehead to the core and my portfolio is currently 90% index funds. However, I am having difficulty determining why I shouldn't exchange my VGTSX index fund for DODFX (Dodge & Cox Int'l) in my Roth account.
Of course the tax consequences are irrelevant for the Roth, so here is a before-tax performance comparison:
1-year 21.03% 18.14%
3-year 4.96% 3.90%
5-year -1.89% -3.03%
10-year 11.63% 9.41%
True the ER for DODFX is .60%, but why should I care if it is performing better? Can somebody please talk me out of this?
