Asset Allocation — Don't Put All Eggs in One Basket
Asset allocation is the way a portfolio is divided among asset classes such as equity, debt and gold. This lesson explains why the mix matters, what diversification and rebalancing mean, how strategic and tactical allocation differ, and what no mix can do.
What asset allocation means
Asset allocation is the division of a portfolio among asset classes such as equity, debt and gold. Because these classes behave differently, the mix largely decides how much the portfolio's value swings.
Each class brings its own main risk: equity brings market risk, debt credit and interest-rate risk, gold price risk and property liquidity risk. Buying several funds of the same category adds funds, not a different asset class.
Diversification
Diversification means spreading money so that the portfolio does not depend on a single asset, sector or issuer. It works across asset classes, which is asset allocation, and within each class, by holding many securities.
It limits the damage any one holding can do, not the risk that a whole market falls.
Strategic and tactical allocation
Strategic asset allocation is the long-term target mix, chosen by reference to goals, time horizon and capacity for risk, and kept through market cycles. Tactical allocation is a short-term shift away from it, based on a view of the markets.
The strategic mix expresses how much risk the portfolio is meant to carry; a tactical shift rests on a market view, which can prove wrong.
Rebalancing
Markets move, and the mix moves with them. If shares rise faster than bonds, the equity share grows beyond the target without the investor doing anything, and the portfolio carries more equity risk than was chosen.
Rebalancing means bringing the portfolio back to its chosen mix, which keeps the level of risk where the investor set it. It does not remove risk or necessarily raise returns.
It also has a cost. Moving money between mutual fund schemes is a redemption from one and a purchase in the other, so it may trigger capital-gains tax and an exit load, which cannot exceed 3% of NAV.
What no allocation can do
No mix is free of risk. An all-debt portfolio still carries credit and interest-rate risk, and gold can fall in price.
Rules of thumb that tie the equity share to a person's age are rough illustrations, not recommendations. The mix that fits a person depends on goals, time horizon and capacity for risk, and personal allocation advice is the work of SEBI-registered investment advisers.
Rules at a glance
Three words for three different acts
Latha, 45, a pharmacist in Coimbatore, has written down a long-term mix of asset classes for her portfolio. That written mix is her strategic allocation.
For a few months she holds less equity than her target because she expects share prices to fall. That is a tactical shift, and her expectation may or may not prove right. Later she moves money so that the portfolio matches the written mix again. That is rebalancing.
Rebalancing after the mix has drifted (illustrative)
- Assumptions for the arithmetic only: Nikhil's chosen mix is half equity funds and half debt funds. The mix and the price moves are made-up figures, not a suggested allocation or a forecast.
- Start: ₹10,00,000, so ₹5,00,000 in equity funds and ₹5,00,000 in debt funds.
- Some time later the equity funds are worth ₹6,00,000 and the debt funds ₹5,20,000. Total: ₹11,20,000.
- Equity share now: 6,00,000 ÷ 11,20,000 = 53.6%; debt share 46.4%.
- Target at the chosen mix: half of ₹11,20,000 = ₹5,60,000 in each.
- Rebalancing: redeem ₹40,000 of equity fund units (6,00,000 − 5,60,000) and invest it in debt funds (5,20,000 + 40,000 = 5,60,000).
Result. After moving ₹40,000 the mix is back to half and half. The redemption may give rise to capital-gains tax and an exit load. Had equity fallen instead, the move would have run from debt to equity.
Key points
- Asset allocation is how a portfolio is divided among asset classes; the mix largely decides how much its value swings.
- Diversification means not depending on a single asset, sector or issuer.
- Strategic allocation is the long-term target mix; tactical allocation is a short-term shift away from it.
- Rebalancing restores the chosen mix after market moves; it does not remove risk, and selling units may trigger capital-gains tax and an exit load.
- No allocation is risk-free, and age-based rules of thumb are illustrations, not recommendations.
Common misunderstandings
- Rebalancing is not a method of raising returns: it restores the chosen level of risk, and it can cost tax and exit load.
- Tactical allocation is not rebalancing: one moves away from the target on a market view, the other returns to it.
- A formula linking equity share to age is not a rule or a recommendation: it is a rough illustration.
Questions people ask
How is asset allocation different from diversification?
Asset allocation is the split among asset classes. Diversification is the wider idea of not depending on a single asset, sector or issuer.
Does a hybrid mutual fund carry out asset allocation?
A hybrid scheme holds more than one asset class within limits set by SEBI's categorisation, such as 10% to 25% equity in a conservative hybrid fund. That is the scheme's mix, not one designed for a particular person.
Who can give a personal asset allocation?
Personal allocation advice is the work of SEBI-registered investment advisers. A mutual fund distributor distributes schemes.
