Getting Started

The annual review that takes twenty minutes

A long-term portfolio needs maintenance, not management. Here is the whole list.

General information. This is journalism, not personalised financial advice. Figures, rates and rules change and vary by country — check current terms before acting. How we work.

What follows is the working version of reviewing a portfolio: the decisions in the order you actually meet them, with the reasoning attached.

Before you start

  • Contribution rate is the variable most worth revisiting.
  • Rebalance to target rather than to a view.
  • Costs and account structure drift and are worth re-checking.

Check the contribution first

Increasing the monthly amount in line with income does more for the outcome than any adjustment to holdings. It is also the only lever entirely within your control.

Setting an automatic annual increase removes the decision permanently. Where income has not risen, holding the contribution steady is a complete answer, and reducing it for a while to rebuild a cash reserve or clear expensive debt is a defensible one rather than a lapse.

Rebalance mechanically

Compare current allocation to target and correct anything that has drifted beyond your band. Doing this with new contributions rather than by selling avoids costs and, in taxable accounts, tax. The point is restoring the intended risk, not expressing a view about what will do well next.

Set the band wide enough that ordinary movement does not trigger a trade, because rebalancing on small drifts buys cost and turnover for a change in risk too small to notice.

Re-check the total cost

Platform pricing, fund charges and your own balance all change, and the cheapest structure at one size is not the cheapest at another. A short annual calculation catches a crossover that would otherwise persist for years.

Switching platforms is administrative and pays every subsequent year. Providers change their pricing more often than investors check it, and the notice usually arrives as a terms update rather than as anything resembling a bill.

Confirm the wrapper is still right

Contribution allowances, employer matching and tax rules change, and so does your income. Using available tax-advantaged capacity before taxable accounts is usually the first-order check. Employer pension matching left unclaimed is the most commonly missed item on any review.

Allowances in many systems are use-it-or-lose-it within a tax year, so the review is better timed to end before that date than to fall on an anniversary of your own choosing.

Update the beneficiaries and the plan

Nominations on pensions and investment accounts are frequently set once and forgotten through major life changes. Re-reading your own written plan is also the moment to notice if your horizon or goal has genuinely changed. Neither takes long and both are ignored for years at a time.

Where it helps most, in many countries a pension nomination sits outside the will and is not overridden by it, so a will rewritten after a divorce or a birth does not on its own correct an old nomination.

Some of this will suit you and some will not, and that is the point.

What not to do at the review

It is not the moment to act on a forecast for the year ahead, because the whole structure exists so that the portfolio does not depend on one. Comparing your return with an index or with someone else only tells you anything if the risk taken was the same, and it generally was not. A single year is too short to judge a strategy built for decades, which is why the fields worth checking are cost, allocation and contribution rather than performance.

In practice, if the review keeps generating an urge to change the holdings, the allocation is probably mismatched to your tolerance, and the fix belongs in the written plan rather than in a trade.

The takeaway

Raise the contribution, rebalance to target, recheck the costs. That is the whole review.

The version you keep doing is the version that works.

Questions readers ask

Is once a year enough?

For a diversified long-horizon portfolio, yes. More frequent review increases activity without improving outcomes.

What if my allocation has drifted a long way?

Rebalance in stages if the tax or cost consequences are significant, and use new contributions to do as much of the work as possible.
