A few questions that could help you make the right decision:
Why did you buy VXUS in the first place?
Do you already hold VTI or do you want to shift from 100% intl to 100% USA?
Why are you inclined to do this move? Because your VXUS lost a 1,000$?
What will you do if VTI drops a 1,000$ after you bought it? Will you go back to VXUS because it might have gone up a 1,000$
Did you make an investment strategy before you bought VXUS? If yes, what is it and why are you changing it now? If not, please think about a strategy that you can stick to.
