Unrealized Cap Gains in Index Funds
I'm looking to put some more money into the market and am considering VTI (Vanguard TM), VEA (Vanguard Europe/Pacific), and VWO (Vanguard Emerging Markets). Then I noticed that all these funds have large unrealized capital gains. 16% for VTI, 17% for VEA, and 34% for VWO. I'm concerned that I might be buying into a tax liability. The Vanguard FTSE All World (ex US) is another possibility which has slightly higher expenses (than VEA/VWO), but less unrealized gains (.34%).
What do you experts think? I'm planning to buy and hold for a long time, but don't like the idea of paying taxes for gains realized by someone else.
