When we think about mutual fund investing, we often obsess over the “right” fund, the perfect allocation, or the best time to enter the market. But experience shows that investment outcomes are shaped far less by fund selection and far more by investor behaviour.
Over the years, three distinct types of investor behaviour emerge in the market.
The first type: the invest and forget investor
This group invests and largely forgets. They may run SIPs in a few mutual funds or index funds and rarely track market movements. Portfolio reviews are infrequent—perhaps once a year.
These investors are usually busy with careers, families, or businesses. They are not trying to outsmart the market or optimise every percentage point of return. There is no panic during market falls and no excitement during rallies.
What works in their favour is consistency. By staying invested and avoiding unnecessary changes, they keep costs low, pay minimal taxes, and allow compounding to work quietly in the background. Over long periods, many such investors earn excellent returns.
An old study done by Fidelity in the US showed that the best-performing clients were those who had either passed away or forgotten they had investment accounts.
The second type: the optimiser
This is, unfortunately, the most common investor today. They follow markets closely, review portfolios frequently, and constantly try to improve results.
They switch funds, adjust allocations, chase recent winners, and attempt to time the market over the next few months. Each decision feels sensible at the time, backed by data, opinions, or forecasts.
But this constant activity creates friction. Taxes, exit loads, and emotional decisions slowly eat into returns. Buying when markets feel comfortable and selling when they feel uncomfortable becomes a pattern. Over time, many such investors end up underperforming the broader market—often by 4–6% compared to a simple index—despite all the effort.
In trying to be smart, they become their own biggest risk.
In investing, activity often feels productive—but it is frequently the enemy of returns.
The third type: the deliberately simple investor
The final group understands markets well—but understands human behaviour even better.
These investors know that most activity does not add value. They prefer simple strategies, low churn, and long holding periods. Portfolios are reviewed occasionally, and changes are usually limited to rebalancing rather than constant switching.
They don’t chase trends or react to noise. Even though they have the time and ability to monitor markets, they choose not to. Their discipline lies in knowing when not to act.
This approach may appear boring, but it is remarkably effective. By keeping costs low, avoiding unnecessary taxes, and staying invested through cycles, these investors often do as well—or better—than those who are constantly trying to optimise.
The real lesson
Markets reward patience, not busyness. Every extra decision increases the chance of making a mistake. In mutual fund investing, simplicity is not a lack of intelligence—it is a sign of it.
So the real question isn’t which fund you own.
What kind of investor are you?
