Why the average investor underperforms the average fund

Here's a statistic that surprises most first-time investors: over a recent decade, one well-known large-cap value fund delivered an annualised return of 21.1%. Meanwhile, the average investor in that very same fund earned just 6.9% annualised over the same period.

Same fund. Same market. Wildly different outcomes. The difference is called the behaviour gap — and understanding it is arguably more valuable than picking the "best" fund.

What causes the gap?

The behaviour gap isn't caused by fees, taxes, or fund manager skill. It's caused by investor timing:

1. Buying after a rally. Money tends to flow into a fund after it's already had a great run — right when future returns are statistically likely to be more modest.

2. Selling during a drawdown. The same investors often redeem during a correction, locking in losses right before markets recover.

3. Chasing last year's winner. Switching funds based on trailing 1-year returns means constantly buying whatever category just peaked.

Three habits that close the gap

Automate your investing. A SIP takes the "when should I invest" decision off your plate entirely. You invest on a fixed date, every month, regardless of headlines.

Match your portfolio to your actual time horizon. Money you need in 18 months shouldn't be sitting in an equity fund in the first place — that mismatch is what causes panic-selling.

Review annually, not daily. Checking your portfolio's value every day makes short-term noise feel meaningful. An annual review, tied to your actual goals, is usually enough.

The takeaway

Fund selection matters, but it's rarely the biggest driver of your personal outcome. Behaviour is. That's the entire premise behind a risk-profiled, SIP-first approach: it's designed to make the "right" behaviour the default one.
