Frequently Asked Questions
What is Dollar Cost Averaging (DCA)?
DCA is an investment strategy where you invest a fixed amount at regular intervals (weekly, monthly) regardless of the asset's price. When prices fall, you buy more units. When prices rise, you buy fewer. This averages out the cost over time and reduces timing risk.
Is DCA better than lump sum investing?
In volatile or uncertain markets, DCA reduces risk and emotional stress. However, research shows lump sum investing outperforms DCA in about 2/3 of cases in trending markets because money is invested for longer. DCA is better for investors without a large lump sum available.
How is DCA different from SIP?
SIP (Systematic Investment Plan) in mutual funds is essentially DCA applied to funds — you invest a fixed amount monthly in a specific fund. DCA is the broader strategy that can be applied to stocks, ETFs, gold, or any asset. SIP automates the DCA process for mutual fund investors.
