Asset allocation is the decision about how much of your money sits in each broad asset class: equity, debt, gold, real estate and cash. It is made before any fund or stock is chosen, and it explains far more of what eventually happens to a portfolio than the choice of fund does.
The reason is that asset classes behave differently from one another, while funds within the same class mostly move together. Two large-cap equity funds will rise and fall in near lockstep. Equity and short-duration debt will not. So the split between them, not the choice between the two funds, is what determines how much your portfolio falls in a bad year.
What each asset class is actually for
Equity is the growth engine. Over long periods it has delivered the highest returns of the main classes in India, and it is also the only one that can fall 30% or more in a year. It belongs to money you will not need for at least five to seven years.
Debt covers fixed deposits, debt mutual funds, PPF, EPF and bonds. Its job is stability and predictability, not returns. It is what lets you leave equity alone during a crash instead of selling it.
Gold is a diversifier. It pays no income at all, but it has historically held or gained value in periods when equity has fallen, which is the whole argument for a modest holding. See the gold hub for how to own it.
Cash is the emergency fund and near-term goals. It is not an investment and should not be judged as one.
A simple worked example, including the rebalancing
Take a Rs 20,00,000 portfolio at a 60% equity, 30% debt, 10% gold allocation. That is Rs 12,00,000 in equity, Rs 6,00,000 in debt and Rs 2,00,000 in gold.
Say over a year equity returns 25%, debt returns 7% and gold returns 10%. The holdings become Rs 15,00,000, Rs 6,42,000 and Rs 2,20,000, a total of Rs 23,62,000.
Equity is now 63.5% of the portfolio rather than 60%. Nothing was done wrong. Good performance itself pushed the portfolio into taking more risk than you chose.
Rebalancing means selling about Rs 83,000 of equity and moving roughly Rs 67,000 into debt and Rs 16,000 into gold, restoring 60/30/10.
Notice what that mechanically does: it sells the asset that has run up and buys the ones that have lagged. It is a rule that makes you sell high and buy low without requiring you to predict anything, which is why it is one of the few genuinely reliable pieces of portfolio discipline.
Choosing a split
There is no single correct allocation, and anyone who gives you one without asking about your horizon and your income stability is guessing. The variables that actually matter are how many years until you need the money, how much of a fall you can sit through without selling, and how stable your income is.
| Horizon and situation | A commonly discussed starting point |
|---|---|
| Under 3 years, goal is fixed | Mostly debt and cash, little or no equity |
| 3 to 7 years | Balanced, often around 40% to 50% equity |
| 7 years or more, stable income | Equity-heavy, often 65% to 80% |
| Approaching retirement | Reducing equity steadily, raising debt |
| Already retired, drawing income | Enough debt to cover several years of withdrawals |
These are illustrations of how the trade-off is usually framed, not recommendations. This site does not give personalised investment advice, and an allocation is a personal decision best made with a SEBI-registered investment adviser if you want it tailored.
The old rule of thumb of "100 minus your age in equity" is a memorable starting point and nothing more. It ignores income stability, existing assets, dependants and whether you have a pension, all of which matter more than the birthday.
The mistakes that cost most
The commonest is having no allocation at all, just a collection of funds bought at different times for different reasons. If you cannot state your equity percentage, you do not have an allocation, you have an accumulation.
The second is owning eight equity funds and calling it [diversification](/glossary/diversification). Eight funds holding the same fifty large-cap stocks is one bet wearing eight labels.
The third is changing the allocation after a crash, which converts a temporary fall into a permanent loss and usually results in returning to equity only after the recovery.
The fourth is ignoring EPF and PPF. For many salaried Indians these are the largest debt holdings they own, and a portfolio that looks 100% equity in a broking app may actually be closer to 60/40 once they are counted. Count everything, then decide.
Rebalance on a schedule, once a year is plenty, or when a class drifts more than five percentage points from target. Track the whole picture with the net worth view rather than fund by fund.
