Dollar-cost averaging (and SIPs)

Dollar-cost averaging (DCA) means investing a fixed amount at regular intervals — say monthly — regardless of price. In India and elsewhere this is often done via a Systematic Investment Plan (SIP).

How it works

Because you invest the same amount each time, you automatically buy more units when prices are low and fewer when high. Over time this can lower your average cost and removes the guesswork of timing.

Why it's powerful

• Removes emotion: contributions happen automatically, sidestepping the behavioural traps of fear and greed.
• Builds discipline: you invest consistently through ups and downs.
• Beats waiting: trying to time the market usually underperforms simply investing steadily. Time in the market tends to beat timing the market.
• Accessible: start with small amounts and increase over time.

A nuance

If you have a large lump sum, investing it all at once has historically done slightly better on average (markets rise more often than they fall) — but DCA reduces regret and the risk of buying right before a dip. For ongoing income, DCA is simply the natural approach.

Key takeaway

Set up an automatic, regular investment into low-cost diversified funds and let it run. Consistency and time, not timing, drive long-term results.
