Frequently Asked Questions
What is dollar cost averaging and how does it work?
Dollar cost averaging (DCA) is an investment strategy where you invest a fixed amount at regular intervals regardless of market price. When prices are low, your fixed amount buys more shares; when prices are high, it buys fewer. Over time, this averages out your purchase price and removes the emotional challenge of trying to time the market.
Is dollar cost averaging better than lump sum investing?
Studies show that lump sum investing outperforms DCA about two-thirds of the time because markets tend to go up over time. However, DCA reduces the risk of investing a large sum right before a downturn and is psychologically easier for most investors. DCA is also the natural approach for most people who invest from each paycheck.
How often should I invest with DCA?
Monthly investing is the most common and practical frequency, especially when aligned with paychecks. Some investors prefer weekly or biweekly contributions. The exact frequency matters less than consistency. Automating your contributions removes the temptation to skip months when markets feel uncertain.
