I've been waiting to put my 401k completely into gold and oil. Think we're close?
The timing of any investment is one of the really hard things to pull off. What I'm looking for is a steady decline of the dollar after it stays below 80 vs. a steady increase in the price of PMs. With a 401K in stocks, you have the added complication of timing a coming market decline.
You have to stay on top of things and listen to your gut and calculate your risk. ;)
