The investor-return gap
In this chapter: DALBAR-style studies in Indian context · Closing the gap — process and rules
The investor-return gap: actual investor returns are 2-4% per year lower than the funds they invested in. Cause: behaviour. Investors put money in after gains (chasing performance) and take it out during losses (panic-selling). The fund's reported return assumes a buy-and-hold investor; real investors don't buy-and-hold.
DALBAR-style research consistently shows this gap globally. In India, Value Research and Morningstar studies show similar 2-4% annual gap. On a ₹10K monthly SIP for 30 years at 12% gross fund return, gap of 3% means ending value of ₹3.5 crore (if held perfectly) vs ₹2.0 crore (typical investor experience) — a 40% gap purely from behaviour. Closing the gap: (1) Automate (SIPs, auto-invest, rule-based rebalancing), (2) Pre-commit (IPS, written rules), (3) Disengage from short-term news (check portfolio quarterly, not daily), (4) Coach through volatility (advisor's value).
Practitioner insight: the gap closes with mechanical rebalancing, not market timing. Annual rebalancing back to target allocation systematically sells appreciated assets and buys depreciated ones — the mechanical version of "buy low, sell high". Studies show 50-100 bps annual outperformance just from this. For self-directed investors: lock the rebalancing into a calendar event (e.g., 1st April every year). For advised: include in IPS as mandatory. Most clients resist rebalancing because it forces selling winners (loss aversion in reverse) and buying losers (recency bias).
