The Pattern That Repeats Every Year
A list of last year's highest returning funds is published. Money flows into those funds. Over the following two or three years a large share of them underperform their own category average. The investors who arrived last experience the underperformance without having experienced the returns that attracted them.
This is not a coincidence and it is not bad luck. It is built into how top performance is generated in the first place.
Why Last Year's Winner Struggles Next Year
A fund tops the chart usually because it was heavily concentrated in whatever sector or theme performed best. That concentration is a bet, and bets that pay off spectacularly one year frequently reverse. A fund that was 40% in one outperforming sector carries that same 40% into the reversal.
Sector leadership in Indian markets rotates. The categories that lead one three year period rarely lead the next.
The Cost of Every Switch
Chasing performance is not free, and the costs are usually invisible until you total them:
- Exit load. Typically 1% if you redeem within a year of purchase.
- Capital gains tax. Short term equity gains are taxed at a higher rate, and every switch resets your holding period.
- Time out of the market. Redemption and reinvestment take days, and markets do not pause for you.
- A reset cost base. You lose the accumulated long term status you had built.
An investor switching every 18 months across a 20 year period can surrender a substantial portion of their final corpus to these four costs alone, even when every individual fund choice was reasonable.
What Actually Predicts Future Performance
Past one year returns have almost no predictive power. Things with somewhat more signal include:
- Expense ratio. Consistently one of the more reliable predictors, because it is the one cost you know in advance.
- Category consistency. A fund that has stayed within its stated mandate rather than drifting.
- Rolling returns, not point to point. How the fund performed across many overlapping periods, which removes start date luck.
- Downside capture. How the fund behaved in falling markets, which tells you whether you will be able to hold it.
The Comparison That Should Worry You
Fund returns and investor returns are different numbers. Industry data across markets consistently shows that the average investor earns less than the average fund they invest in. The gap comes entirely from buying after good performance and selling after bad performance.
The fund's return is what the fund earned. Your return is what your behaviour left you with.
What to Do Instead
Choose a category that matches your goal and horizon. Pick one or two funds within it with reasonable costs and a consistent mandate. Then judge them against their own benchmark over three years, not against whatever topped last year's list. Change funds when the mandate changes or the underperformance against its own benchmark persists, not because something else did better.
Frequently Asked Questions
Should I ever switch mutual funds?
Yes, when the mandate changes, the fund consistently trails its own benchmark for three years, or your goal changes.
How often should I review my funds?
Once a year is sufficient. More frequent review encourages switching that costs more than it gains.
What is the tax cost of switching?
A switch is a redemption plus a fresh purchase. Gains are taxable and your holding period resets.
Is a high return fund always riskier?
Often it is more concentrated, which produces both the outperformance and the subsequent reversal.
What matters more than past returns?
Expense ratio, mandate consistency, rolling returns and how the fund behaved during market falls.
