Two different problems: the wrong target, or drift from the right one
Most allocation reviews jump straight to percentages: equity has grown, so sell some; gold has lagged, so add more. That skips the more important question. Before asking whether your portfolio is near its intended allocation, ask whether that intended allocation is still right.
These are different problems with different fixes. Confusing them is how investors end up rebalancing diligently into a mix that no longer suits their goals, or tearing up a sound plan because markets had an unusual year.
The target is wrong
- What has gone wrong
- The intended mix no longer suits the goal it serves.
- Typical cause
- The goal date came closer, its amount or priority changed, funding moved well ahead or behind, income or liquidity needs changed, or the risk was never sustainable.
- What the fix looks like
- Redesign the target for that goal first. Moving money comes later, and only as far as the new target requires.
- What a mistake looks like
- Rebalancing faithfully back to a target that no longer fits.
The portfolio has drifted
- What has gone wrong
- The intended mix is still right; the portfolio has moved away from it.
- Typical cause
- Different asset classes moved by different amounts, contributions went into one place, or old holdings were never aligned.
- What the fix looks like
- Move back towards the target only when the gap is material: often through new contributions before any selling.
- What a mistake looks like
- Redesigning a sound target because one asset class had a good or bad year.
If you are still deciding what your allocation should be in the first place, start with how asset allocation is decided. This page is about a portfolio you already hold.
A five-step diagnosis for an existing portfolio
Work through these in order. The first four test the target; only the last measures drift.
- 01
Which goal is each part of the portfolio for?
Money with no assigned goal cannot be judged as too risky or too safe. Map holdings to goals before looking at percentages.
- 02
How far away is each goal, and how funded is it?
A goal that is now near, or already largely funded, may need less dependence on markets. One that is behind may need higher contributions or a revised target before it needs more risk.
- 03
Is the risk still informed and sustainable?
Check what each goal needs and what fall you could absorb without a forced sale or a panicked exit. Comfort alone is not the test; capacity and behaviour both count.
- 04
Have life, income or liquidity needs changed?
A new dependant, a job change, a business, a large planned expense or weaker emergency reserves can change the right allocation even if markets have not moved.
- 05
Only now: how far has the portfolio drifted?
Compare the actual mix with the target you have just confirmed. Small gaps can be left alone or corrected through new money; large ones may justify rebalancing.
Step three is where most of the judgement lies. How much risk a goal genuinely needs, and whether you can live with it, is covered in taking informed risk. Age can frame that conversation but should not settle it, as asset allocation by age explains.
What should, and should not, make you change the target
Good reasons to revisit the target
- A goal is now much closer than when the mix was set
- A goal's amount, priority or date has changed
- A goal is well ahead of, or well behind, its funding path
- Income stability, liabilities or emergency reserves have changed
- You discovered in a real fall that the risk was more than you could hold
- A life event has changed what the money is for
Not, on their own, reasons to change it
- Markets have risen strongly, or fallen sharply
- A birthday or a new decade
- A forecast, a headline or a confident prediction
- One asset class topped last year's return table
- A friend's or colleague's portfolio looks different
Market movements still matter, but mostly through drift. They change the portfolio; they rarely change the goal.
After a rally, should you rebalance straight away?
Not automatically. A rise in equity pushes the portfolio above its equity target, but a small gap is not a problem worth paying to fix. Selling has costs: capital gains tax, exit loads on recent units, and the risk of turning a disciplined plan into a reaction to every market move.
Three questions keep this proportionate. Is the gap large enough to change the risk the goal is carrying? Can new SIPs or lump sums be directed to the under-weight side instead of selling? And is this money approaching its goal, where locking in progress matters more? When the answer points to action, the mechanics belong to portfolio rebalancing.
Strategic, tactical and dynamic: what each means in a review
These labels describe how an allocation is managed. In a review, each one raises a slightly different question.
- Strategic
- A long-term target mix for a goal, restored when it drifts. The review question: is the target itself still right for the goal today?
- Tactical
- A deliberate, temporary tilt away from the target. The review question: was the tilt intended, sized sensibly and still justified? If no one can say why it exists, it is drift with a story attached.
- Dynamic
- The mix shifts according to a rule, often valuation-based, as in dynamic asset allocation or balanced advantage funds. The review question: do you understand the rule, and how does that fund's moving mix combine with the rest of your portfolio?
Choosing between these approaches when building a portfolio is a strategy decision, covered in tactical vs strategic asset allocation.
An illustration: one portfolio, two different answers
Consider a fictional investor with two goals in one portfolio: a home down payment due in about two years, and retirement more than twenty years away.
Down payment · about 2 years
This money was invested in an equity-heavy mix when the purchase was a distant idea. The date is now close and fixed.
A target problem. The mix needs redesigning for a near, essential need.
Retirement · 20+ years
The target still fits. After a strong year for equity, the portfolio sits somewhat above its intended equity share.
Modest drift. New SIPs can be pointed at the under-weight side; nothing needs to be sold yet.
Looking at the portfolio as one pie chart would hide both findings. The combined mix might even look “balanced” while the down-payment money carries risk it cannot afford.
When the right answer is no change
A review that ends with “leave it alone” is not a wasted review. If each goal's target still fits, the portfolio is reasonably close to it and nothing in your life has changed what the money is for, then the most valuable action is to keep contributing and not interfere.
If the allocation is fine but individual funds are the concern, that is a different check: whether your existing funds still suit your goals and risk. The broader set of reasons to look closer is in the portfolio health check.
The FinEdge perspective
An allocation is not a one-time choice that is right forever, and it is not a number to chase back to after every market move. It is the expression of what each goal needs, given its time, its funding and the risk you can carry. Review the goal first and the percentages second.
Drift is a reason to look. A changed goal is a reason to act. A good year in the market is neither.
