You chose 60% equity and 40% debt. A strong stock-market year changes it to 72% equity. The portfolio has quietly taken on more risk than you originally intended.
Rebalancing is a way to bring that risk back into line.
Define the target first
Choose an allocation based on goals, horizon, cash needs and capacity for loss. Rebalancing cannot rescue a target that was unsuitable from the start.
The often-repeated claim that allocation determines 90% of every investor's return is not an appropriate universal fact. Allocation is central to portfolio behaviour, but the precise result also depends on markets, costs and decisions.
Choose a workable rule
A calendar review or a tolerance band can reduce impulsive trading. For example, a five-percentage-point band around a 60% equity target would prompt a review at 55% or 65%. That is an illustration, not a rule every investor must adopt.
Do not confuse a percentage-point deviation with a relative percentage change. Write the rule clearly enough that you could follow it during a market fall.
Use new money where possible
Directing contributions to an underweight asset can restore balance without selling the overweight holding. Withdrawals can also be taken with the allocation in mind.
If a sale is needed, check liquidity, exit loads, holding periods and the relevant tax. Equity, debt, gold and property do not share one capital-gains rule.
The ₹1.25 lakh long-term-equity threshold is aggregate across eligible assets. It is not a universal exemption on every rebalancing sale, and it may already be used elsewhere in the return.
Understand the trade-off
Rebalancing can sell an asset that later keeps rising or buy one that continues falling. It does not mechanically capture excess returns or guarantee a ratchet of wealth into safe assets.
Its main benefit is keeping the portfolio near the intended risk level and reducing decisions driven by recent performance.
Review the target when the goal or household circumstances change. Otherwise, use a consistent process and avoid turning routine maintenance into constant portfolio churn.
