I will not buy commodity futures. The way it works is that half the buyers win and half lose. You have to be more than shrewd, follow it hourly, and be lucky on top of that. But the commodities themselves are a different matter altogether. You still have to be shrewd to buy low and sell high, but they are never worth nothing. I like the way they don't move with the stock market, which helps out during crashes and slumps. I like real estate for the same reason. I keep about 5% each in precious metals and in real estate funds and ETFs. There are times I go to 10%.
