I ask because I had planned to invest a lump sum worth about 5% of my total assets tomorrow, 6/24, according to my asset allocation of 60% VTSAX, 30% VTIAX, and 10% in a bond fund. This date just happens to be the day after Brexit.
Is there a way I can make sure tomorrow's investment executes in a way that helps maintain my AA? Since mutual fund balances don't update in real-time on Vanguard's website, I'm not sure how to determine the amount of shares to buy tomorrow afternoon. I imagine my VTIAX balance will not look the same at the end of the day tomorrow as it does right now.
I realize I could hold off and buy after I learn my new end-of-day balances tomorrow, but that feels a little "market-timingy" since I'd planned to do this trading anyway. Thanks for any advice!
I check ETFs VXUS and VTI percentage changes toward market close to get an idea.
