I was pretty much 100% in gold and silver up to mid-2011. Stock markets crashed, gold and especially silver were skyrocketting. It made me nervous. I went half-gold, half-stocks at this very moment. I had acquired a part of this gold & silver below market value, and dumped some gold and all my silver almost at the top, buying cheap stocks instead. I almost doubled my net worth this year. Pure luck, though, but you bet I learned the values of diversification and rebalancing.
