What Is Dollar Cost Averaging?
Dollar Cost Averaging (DCA) is the practice of dividing a total sum of money into equal, smaller purchases made on a fixed schedule, rather than investing it all in a single transaction. Instead of trying to identify the "perfect" entry price, a DCA investor buys $50, $100, or $500 of an asset every day, week, or month, regardless of whether the market is up, down, or sideways. Academic literature on averaging strategies frames this as a way to convert a single, high-stakes timing decision into a long series of smaller, lower-stakes decisions, which mechanically reduces exposure to any one price point.
