The case for SIP

I started systematically investing Rs 1,000 every month in a mutual fund. Over 3 years, the total invested amount is Rs 36,000 and the current value is about the same. No profit. No loss.

My question is, if today someone invests Rs 36,000 lumpsum in the same scheme of the same fund, would it be the same as I did in the form of SIP 36 months ago?

Technically, yes.

If someone invests in the same fund today, their purchase Net Asset Value, or NAV, will be similar to your weighted average purchase NAV for over the last 3 years (since you mentioned your portfolio is more or less at no profit or no loss).

But reality is different.

It is important to note you are speaking from the benefit of hindsight. Market movement is never a straight line, rather it is a series of ups and downs (typically defined as volatility). Thus, in the short term, it is likely that the current value of your investments could be the same or in many cases even lower than the purchase price. But over the longer term you should expect to make reasonable returns on your equity investments.

The two visual representations (click to enlarge) will emphasize the importance of thinking long term (7-10 years at the least) when investing in equities.


Over the last 20 years, there have been multiple occasions where the market fell more than 20% from the peak and could have taken some time to recover. Over the longer term, returns have been reasonable.


Observe the return over varying time periods. As the holding period increases, the range of return narrows, but there is a greater probability of positive returns.

Keep these simple rules in mind while investing in equities:

  • A long-term investment horizon
  • Invest regularly through SIPs to reduce market timing risk
  • Be mentally prepared for potentially large drawdowns in the short term

 So, it is a fact that in stock market there can be compounding and de compounding (if i can use the word). What happens to all the dividends paid out when this gentleman started his investments, all washed out. He cannot technically say there is no profit or gain. He is absolutely under loss, as even the dividends which he might have received, if he had invested in stock is washed out . What about the opportunity cost of FD rates. In a nutshell, all losses. This long term investment horizon is market technique. What he should have done is, redeem that is sell the MF in part when market was peaking, if it was ever peaking.
Please do not keep saying about long term, this is not true.
