Is Bogleheadism (index fund investing) dead?
The reports of my death have been greatly exaggerated. - Twain I use index funds in my retirement planning, but don't stick to just S&P 500 index funds. Suppose I balance my money 50/50 between Small Cap and Large Cap and say I have $10,000.  I'd buy $5,000 of an S&P Index fund and $5,000 of a Russell 2000 index fund. Now, fast forward a year.  Suppose the S&P Index fund has $4900 and the Russell Index fund has $5200.   Sell $150 of Russell Index Fund and buy $150 of S&P 500 Index funds to balance.  Repeat that activity every 12-18 months.  This lets you be hands off (index fund-style) on your investment choices but still take advantage of great markets.   This way, I can still rebalance to sell high and buy low, but I'm not stressing about an individual stock or mutual fund choice. You can repeat this model with more categories, I chose two for the simplicity of explaining.
