In this game, rocks and other 'hard assets' do beat paper.

Having exposure to other asset classes during last 10 years was clearly the way to maintain a portfolio. Heck, even just buying Treasuries would have been better than buying and holding stocks. But then again, who buys and holds stocks? Oh, right. All those millions of people that only have stocks as an option in their 401(k) and are bombarded by the Wall Street manta: buy buy buy! The DOW is going to 36,000! Stocks always come back! Right. What a load of crap.
I don't have any problem admitting that I have no clue at all which asset class will lead over the next 10 years and which one will lag. That's an awfully big bet to make anyways, and one I don't need to. By maintaining exposure to as many asset classes as possible, and maintaining a risk management strategy, I'll ensure that I'm taking part in the best performing asset classes.
