When investors look for a mutual fund, the most common shortcut is to pick the scheme that delivered the highest returns over the past one or three years. The logic feels sound, because what has worked in the past should continue to work in the future. Salespeople find it easy to recommend such schemes, and investors find the numbers convincing.

The data, however, tells a different story.

What the Numbers Show

We examined all open-ended equity mutual fund schemes with assets above Rs 250 crore as of December 2016, and tracked their performance from CY2000 to CY2016. The schemes were ranked by past returns and divided into quartiles, with Q1 representing the top 25 per cent.

The results are telling:

• Only 35% of Q1 schemes retained their Q1 ranking in the following year. The remaining 65% slipped to lower quartiles.
• Over a three-year horizon, only 29% of Q1 schemes held their position. 71% did not.

To put this in perspective: the chance of correctly calling a coin toss is 50%. The chance of a top-quartile scheme staying in the top quartile over three years is 29%. Picking funds by past returns alone is, statistically, worse than a coin toss.

Why Past Returns Are an Unreliable Guide

Repeating top-of-the-table performance is genuinely difficult, even for capable fund managers. Markets shift, sector cycles turn, and styles that produced strong returns in one period often underperform in the next. A scheme's last-year return reflects the market conditions of the last year, not the conditions ahead.

A useful analogy: no one drives a car looking only at the rear-view mirror. Investment decisions deserve the same approach. Past performance is a single data point, not a forecast.

Bet on the Jockey, Not the Horse

If past returns are an unreliable guide, what should drive the choice? The old adage applies here: bet on the jockey, not the horse. The fund manager, not the scheme, is the more reliable signal.

A structured way to evaluate a fund manager is the 4Cs framework:

• Clarity of Approach and Investment Style. Does the manager articulate a clear philosophy, and does the portfolio reflect it?
• Consistency of Performance. How does the manager perform across market cycles, not just bull runs?
• Capability of Fund Manager and AMC. What is the depth of research, risk management, and operational support behind the manager?
• Class of the Manager. What is the manager's experience across cycles, and how have they handled drawdowns and recoveries?

These four factors, assessed using both qualitative judgment and quantitative measures, provide a more durable basis for selection than a one-year return number.

In Closing

Choosing the right scheme can support long-term wealth creation. Choosing the right fund manager, evaluated on the right parameters, can enhance it meaningfully. The standard disclaimer, that past performance is no guarantee of future results, is more than a regulatory line. The data behind it is consistent and clear, and it deserves to be taken seriously.
