Yes, time to rebalance!
I mainly do this buying, as I get a lump sum around this time. Thought I'd share my current allocation.
VWELX 25% A balanced fund, approx 35/65 bonds to equity, big cap
VWINX 10% Conservative balanced income fund, 60/40 bonds to equity
VEXMX 10% Extended market inbetween russel3000 and sp500
VEIPX 10% Equity income, big dividend stocks
VEIEX 10% Emerging markets
VWIGX 5% International growth, about half in Europe
VGSIX 10% REIT index
VISVX 5% Small cap value
VMGIX 10% Midcap growth
VFIAX 5% SP 500 INDEX
I'm aiming for a 15/85 bond equity split, and want to be slightly overweight on midcap and emerging markets, hence the complexity.
