The behaviour gap: what funds earn vs what investors earn
The fund earned fourteen percent. Ramesh earned eight.
Sit with that sentence for a moment, because it is not a typo. The same mutual fund, over the same ten-year period, delivered fourteen percent annualised returns on paper. Ramesh — a dentist in Guwahati, disciplined in his clinic, meticulous with his patients, a man who flosses daily — invested in that fund and walked away with eight percent.
The missing six percent is not a fee. It is not a tax. It is not an expense ratio. It is Ramesh.
Here is what happened, reconstructed from a portfolio review that could have been any of two hundred reviews we have done at Dhansanchay.
Ramesh started a SIP in 2016. Good fund. Solid track record. The SIP ran quietly for two years, compounding as SIPs do — invisibly, without drama. Then came 2018. Markets corrected. Ramesh's portfolio showed red. His colleague at the hospital — an orthopaedic surgeon who watches CNBC between surgeries — said the correction would deepen. "Wait it out. Stop the SIP. Start again when it hits bottom."
Ramesh stopped the SIP in October 2018.
The market bottomed in the same month. By the time Ramesh's colleague declared the coast clear — March 2019 — the fund had already recovered twelve percent from its low. Ramesh restarted the SIP. He had missed the best buying opportunity of the cycle, and bought back in at a higher NAV.
Then came 2020. Covid. The fastest crash in market history. Ramesh, remembering 2018, did not stop the SIP this time. Progress. But he also did not deploy the lump sum he had been holding in his savings account — money earmarked for exactly this kind of correction. Because the fear was not theoretical this time. It was a pandemic. His clinic was shut. The world was ending.
Then came 2021. Markets rallied. Ramesh felt vindicated. He added two more SIPs — small-cap funds, both recommended by a WhatsApp group that his anaesthetist runs. The small-caps soared in 2021 and 2022. Ramesh told Meera he was "diversifying."
Then came 2023. Small-caps fell twenty-five percent. Ramesh redeemed both — at a loss — and moved the money to a fixed deposit. "At least FD is safe," he said. The small-cap funds he exited recovered fully within eight months.
This is the behaviour gap. And it is not unique to Ramesh. It is the most expensive force in retail investing.
Research consistently shows that the average equity mutual fund in India has delivered twelve to fourteen percent annualised returns over the past fifteen years. The average equity mutual fund investor has earned eight to ten percent over the same period. The gap — three to four percent per year — is caused entirely by timing. Investors buy after rallies, when confidence is high. They sell during corrections, when fear is high. They enter at peaks and exit at troughs. The fund compounds beautifully on paper. The investor's actual experience of the fund is significantly worse.
Three to four percent per year does not sound like much. Compounded over fifteen years on a portfolio of ₹50 lakh, it is the difference between ₹2.7 crore and ₹1.6 crore. Over one crore of wealth — not lost to the market, not taken by fees, but surrendered to behaviour.
(Illustrative. Actual returns depend on fund selection, market conditions, and individual behaviour.)
Why smart people are not immune
The behaviour gap does not discriminate by intelligence, education, or income. Ramesh is a dentist. His colleague is a surgeon. Their WhatsApp group includes a CA, two engineers, and a retired IAS officer. Every one of them has, at some point, made a timing decision that cost them money — because the decision felt rational in the moment.
It felt rational to stop the SIP in 2018 because the market was falling. It felt rational to avoid deploying cash in 2020 because the world was shutting down. It felt rational to chase small-caps in 2021 because they were up fifty percent. Each decision, in its moment, had a compelling story behind it. And each story was expensive.
The Bollywood version: picture Ramesh as the hero who keeps arriving at the railway platform just as the train pulls away. He runs faster each time. He is not lazy or stupid. His timing is just always, always wrong — because he starts running when the train has already started moving, not when it was waiting at the platform.
The cure is not intelligence — it is structure
The families we work with at Dhansanchay who avoid the behaviour gap share a set of habits that have nothing to do with market knowledge.
Their SIPs are automated. They run on the fifth of every month, regardless of whether the Nifty is up or down, regardless of what happened in US markets last night, regardless of what the WhatsApp group says. The SIP does not require a decision. It requires a standing instruction.
They have a dip protocol. A pre-agreed, written-down plan that says: if the market falls X percent, deploy Y amount from the liquid fund. No debate. No "let's wait for the bottom." No asking the orthopaedic surgeon. The protocol was written during a calm market, when thinking was clear. By the time fear arrives, the decision is already made.
And they have a review calendar tied to life, not to headlines. The review happens in June because the child's school year is ending and the next year's fees need planning — not because the budget session spooked the market. The trigger is the family's life. The market is noise.
The Dhansanchay lens
This is, in many ways, the entire argument for advisory. The fund does not need an advisor. The fund will compound with or without you. It is a machine that runs on mathematics.
The investor needs the advisor. Because the investor is human — subject to fear, greed, overconfidence after a good year, and paralysis after a bad one. The advisor's job is not to pick better funds. It is to prevent the investor from turning a fourteen-percent fund into an eight-percent experience.
The next time someone asks what an advisor does, the answer is not "picks funds." The answer is: "protects six percent a year from disappearing into behaviour."
That is not exciting. It is worth crores.
