For every month since 1800 we calculate our return over the next year from both (i) investing a lump sum or (2) splitting that lump sum into 12 equal monthly payments and making them over the next year.

In fact, since 1800 DCA only won 27% of the months. And since 1970 only 26% (and since 2000 the percentage rises to 37% due to the two bear markets in that decade).

有能够猜中将来熊市的能力不如直接猜顶摸底。
