SIP Investment

“SIP of Rs 5000/ – started on 1st July 2010, has become Rs 18.84 lacs as on 1st July 2021 (Actual Figure)”

What is SIP?

SIP is a short form for Systematic Investment Plan, As the name suggests, it is a method of regular investments. Like when u invest a Fixed amount every month in a Mutual Fund Scheme, it is called a SIP.

Where to Invest SIP?

It is advised to start the SIP in a Diversified Equity Fund, for better long-term growth. Systematic Investment Plan works on the principle of SNOWBALL theory – the longer you go, the bigger it grows. Volatility is the food for Investing.

How to open a SIP Account?

Opening a Systematic Investment Plan account is very simple. You just need to check if you are a KYC compliant, and then sign an ACH mandate with your MF Distributors, for monthly deduction of the SIP amount; that’s it!



Systematic Investment Plan is a very convenient method of investing in mutual funds through standing instructions to debit your bank account every month, without the hassle of having to write out a cheque each time. Currently, mutual funds have 3.73 crore SIP accounts through which investors regularly invest in Indian mutual fund schemes.


SIP is nothing but a piggy bank! You should assign all your SIP to your Financial Goals, like home painting, Foreign Vacation, Social Gifting,  for Kids education etc. This will help you maintain the discipline of investments and inspire you to save.


Always check your estimated future Value, before starting a Systematic Investment Plan; I have given below the reference table of Rs 1000/- per month at an assumed rate of 12% p.a*, just for your help.

Tabular Table SIP

*Note: Above the table is just a ready reference for your help. 12% p.a is just an indicative return, taken for the purpose of calculation. The actual Average ROI of Top 5 Diversified Equity funds is 18.5% p.a, in 20 Years period.


Always allocate your Systematic Investment Plan according to your target period and Liquidity requirement. Like, if you want to start a SIP for a shorter period (< 5 years), they prefer a large Cap or Hybrid Fund, and if you are looking to start investing for a longer period (7-10 years or more), you can select Midcap or Small-Cap Funds. I have given below the real historic chart of some of the long-term SIPs in Indian Equity Mutual Funds:

One can see the advantage of investing over the long term – An investment of Rs 5000 per month has been converted to huge wealth if you have kept the discipline of investing.

Behavioural finance is a very interesting stream of economics that studies the irrationalities of human behavior when it comes to financial decision making. It also explains why most investors lose money in the financial markets and / or under-perform the market.

Behavioural Finance: A few basic tenets of irrationalities

Mental Accounting

 If we earn USD100 from gambling or windfall gain, we are more likely to spend it for giving party to our friends. We tend to create different buckets in our mind (Hard earned money / windfall gain / inheritance etc) as to the source of money and it drives our end use. Money however has the same color and carries the same purchasing power irrespective of the source. An electronics store doesn’t question the source of money when the customer approaches to buy goods. 

It also has an implication on our investing behaviour in Behavioural Finance. We are likely to be less conservative in our investments if in our mind the source of money is other than hard earned money. We are more likely to invest the money in risky assets and therefore probably lose it. 

Loss Aversion

Various psychology tests have concluded that the pain from losing USD100 far outweighs the joy of earning the same sum of money. When we are earning a positive return on an investment, there is also a temptation to book profit lest we lose the money that we have earned. It explains why most of the scrips in the portfolio of an investor are loss making scrips (Read – poor investments) and therefore underperform the market.

When we are losing money on an investment, we tend to hold on to the scrip as we are averse to book losses. Scrips which are delivering profit are sold off and we are left with a less than an optimum portfolio.

There is an old saying that amateur investors book profits while professional investors book losses.

Herd behaviour

There is a tendency of retail investor to follow the latest trends and / or fancies of investment ideas. A very good example was during IT bubble of year 2000 when dot com companies were losing money / burning cash but were the darlings of the markets. Portfolios which would stick to time tested principles of picking companies with strong cash flow and low valuations were under-performing the market. Recession is invariably preceded by euphoria in financial markets and not surprisingly the world went into a tail spin with the collapse of IT Bubble in 2000. Similar euphoria in stock markets was visible in 2008 when the world was beginning to see signs of financial crisis 

Parallels today can be drawn in the valuation of E Commerce companies like Amazon, Flipkart which keep burning cash but carry exorbitant valuations. 

Herd behaviour in Behavioural Finance is what Warren Buffet cautions in his famous saying “investors should be greedy when markets are in a state of panic and panicky when markets are greedy”.

Price Anchoring

When we buy a book and find it to be not so interesting, we tend to complete it just because we paid for it. In the process we ignore, the cost of book is a sunk cost and the time could be better utilized in something more productive. When we spend heavily on the maintenance of our vehicle and end up encountering another maintenance issue which requires more expenditure, that we have spent already on the maintenance of our vehicles drives our decision to spend more than replace the vehicle.

Similarly, we get anchored to certain price points which could be the purchase price of our scrip, the high that it made yesterday etc. We end up not buying a scrip as it has moved few rupees where it was trading the day before and lose several times the money.

Investors need to train themselves to ignore the cost of purchase / other price anchors as sunk cost / missed opportunities and be oblivious to them in their investment decisions

High Self rating

A survey concluded that 80% of the drivers rate themselves as above average drivers. Most of the investors rate themselves better than others and their over confidence on their abilities as an investor drives the under-performance of their portfolio.

Our mind tends to process information and give a lot more credibility to data points / news that in sync with our investment philosophy. It strengthens our self-esteem and re-inforces our belief in one self.

We are unwilling to accept and process information that is not in sync with our themes and we discount it as just another view or a stray opinion. It makes us over-look important data points and ignore mistakes which leads to holding of sub-optimal investments. We also end up adding more money to “average cost” in case of price corrections in such scrips to re-inforce our belief in self. It is like putting good money behind bad money. 

If we are over-excited about an investment, we are more likely to lose money as we have over-looked risks associated with the scrip. 

The most difficult thing is to manage our emotions which influence our decision making, move against the herd and carry conviction in our investments with the humility that we are not infallible and prone to mistakes. These are the hallmarks of a great investor.
