Second, divide your money among stocks and bonds, big and small, and value and growth. The pair notes that a less volatile portfolio may earn more over time than one with higher volatility and identical average returns. “If you don’t have big drops, the portfolio can compound at a greater rate,” Mr. Goldie said.

Finally, rebalance, by selling your winners and buying more of the losers. Most people can’t bring themselves to do this, even though it improves returns over the long run.
