There are two common ways to invest in mutual funds: a Systematic Investment Plan (SIP), where you invest a fixed amount regularly, or a lumpsum, where you invest everything at once.
How SIP works
With a SIP you invest, say, ₹10,000 every month. When prices are low you receive more units, and when they are high you receive fewer. This averaging out of purchase cost is called rupee cost averaging, and it reduces the stress of timing the market.
How lumpsum works
A lumpsum puts your full amount to work immediately. If markets rise, the entire sum benefits from the start. If you invest just before a fall, however, the loss can be larger and recovery takes time.
Which tends to win?
In steadily rising markets, a lumpsum usually ends up ahead because more money was invested for longer. In volatile or falling markets, SIPs often do better because later purchases happen at lower prices. Over long periods the difference is often smaller than people expect.
Choosing for yourself
- Regular income and no large pool of cash: SIP is the natural fit.
- Received a bonus or maturity amount: consider splitting it into staggered instalments.
- Worried about timing: SIP builds discipline and habit.
