"How I would invest a $100,000 windfall: I love giving 500-year-old investment advice from a German banker called Jacob Fugger the Rich: Keep one-quarter each in stocks, bonds, real estate and gold coins. Gold coins were the currency of his day. In modern-day terms, he's talking about T-bills. What he's telling you is to dynamically rebalance-sell asset-mix winners and buy asset-mix losers. All sorts of studies show the more you dynamically rebalance, the better your long-term returns. It sounds easy, but it's incredibly difficult to do."
