Dollar-Cost Averaging in a Depression

"Then he gave me a little history lesson. In the history of financial markets, people talk about different periods. In the Great Depression, did people make money or lose money? His answer: They lost money only if they sold. You would have done pretty well if you just kept investing the same amount of money at regular intervals, a technique known as dollar-cost averaging. From 1929, the peak of the crash, to 1939, over that 10 years, if you dollar-cost averaged in the S&P 200 every month, you had a 13 percent return annually."
