AB Dollar cost averaging—spreading an investor’s stock purchases evenly over time—is widely touted in the popular press because of the mathematical fact that the average cost per share is less than the average price. The academic press has generally been skeptical and attributes dollar cost averaging’s popularity to investor naiveté and cognitive errors.
