Is Bogleheadism (index fund investing) dead?
From http://blog.ometer.com/2008/03/27/index-funds/ , Lots of sensible advisers will tell you to buy index funds, but   importantly, the advice is not simply "buy index funds."   There are at least two other critical details: 1) asset allocation   across multiple well-chosen indexes, maintained through regular   rebalancing, and 2) dollar cost averaging (or,   much-more-complex-but-probably-slightly-better, value averaging). The   advice is not to take your single lump sum and buy and hold a   cap-weighted index forever. The advice is an investment   discipline which involves action over time, and an initial   choice among indexes. An index-fund-based   strategy is not completely passive, it involves some active risk   control through rebalancing and averaging. If you'd held a balanced portfolio over the last ten years and rebalanced, and even better if you'd dollar cost averaged, you'd have done fine. Your reaction to the last 10 years incidentally is why I don't believe an almost-all-stocks allocation makes sense for most people even if they're pretty young. More detail in this answer: How would bonds fare if interest rates rose? I think some index fund advocacy and books do people a disservice by focusing too much on the extra cost of active management and why index funds are a good deal.  That point is true, but for most investors, asset allocation, rebalancing, and "autopilotness" of their setup are more important to outcome than the expense ratio.
