What a Financial Advisor Would Actually Check in Your Portfolio
Last updated August 2026
Short answer
Eight things: allocation against your real horizon, look-through concentration, fund overlap and total cost, asset location across account types, tax lots and wash-sale exposure, cash drag, beneficiary designations, and the household view including a spouse's accounts and any equity compensation. Four of them are arithmetic you can run yourself. The last two genuinely need a person, and the most consequential thing found in a typical review is not a portfolio issue at all. Walnut is informational and is not an investment adviser.
Nobody publishes this list, which is odd given how many pages exist about whether to hire an advisor. Knowing what the review actually consists of tells you two useful things at once: which parts you could do this afternoon for nothing, and which parts you are really paying for. Both are worth knowing before the fee conversation rather than after.
The eight items
| What is checked | What it means | Can you do it yourself? |
|---|---|---|
| Allocation against your real horizon | Whether the stock and bond split matches when you actually need the money, not when you said you would retire | Partly |
| Look-through concentration | What share of the whole portfolio sits in one company or one sector once you look inside the funds | Yes |
| Fund overlap and total cost | Whether two funds are doing one job, and the weighted expense ratio across everything you hold | Yes |
| Asset location across account types | Whether tax-inefficient holdings sit in the sheltered accounts and efficient ones in the taxable account | Partly |
| Tax lots and wash-sale exposure | Which specific lots would be sold to rebalance, and whether recent purchases have disallowed a loss | Partly |
| Cash drag | How much is sitting uninvested, deliberately or otherwise, and what it is costing | Yes |
| Beneficiary designations | Who inherits each account, and whether that still reflects your intentions | No |
| The household view | Your accounts alongside a spouse's, a pension, property, a business, and any equity compensation | No |
1. Allocation against your real horizon
What it is. Whether the stock and bond split matches when you actually need the money, not when you said you would retire.
The measurement is easy and the judgement is not. A 70/30 split is right or wrong only relative to a horizon, a spending plan and how you behaved the last time markets fell. An advisor is testing the assumptions behind the number rather than the number.
2. Look-through concentration
What it is. What share of the whole portfolio sits in one company or one sector once you look inside the funds.
The common finding is not a deliberate bet. It is three broad funds that each hold the same handful of large companies, so the portfolio is far more concentrated than the fund count suggests. This is arithmetic and you can run it yourself.
The method is in how to check portfolio concentration.
3. Fund overlap and total cost
What it is. Whether two funds are doing one job, and the weighted expense ratio across everything you hold.
An advisor will usually find at least one pair of funds that substantially duplicate each other, and will know the weighted cost within minutes. Both are measurable without any professional judgement at all.
See how to find overlap in your ETFs and what an expense ratio is.
4. Asset location across account types
What it is. Whether tax-inefficient holdings sit in the sheltered accounts and efficient ones in the taxable account.
The principle is simple and applying it needs a view of your whole tax picture, current and expected. It is one of the clearest places a professional adds value, because the gain is real, recurring, and invisible if nobody looks across accounts.
5. Tax lots and wash-sale exposure
What it is. Which specific lots would be sold to rebalance, and whether recent purchases have disallowed a loss.
Most people never look at lot-level detail, and rebalancing without it can realise a much larger gain than necessary. The wash-sale interaction across accounts, including a spouse's, is the part that catches even careful people.
See cost basis and the wash-sale rule, which is the part that catches careful people because it reaches across accounts.
6. Cash drag
What it is. How much is sitting uninvested, deliberately or otherwise, and what it is costing.
Idle cash accumulates quietly from dividends, a sale never reinvested, or an emergency fund that grew past its purpose. It is easy to measure and easy to miss.
7. Beneficiary designations
What it is. Who inherits each account, and whether that still reflects your intentions.
Not a portfolio question and routinely the most consequential thing found in a review. Beneficiary designations override a will, and they are frequently years out of date after a marriage, divorce or death. Almost nothing prompts you to check.
8. The household view
What it is. Your accounts alongside a spouse's, a pension, property, a business, and any equity compensation.
Two individually sensible portfolios can combine into something nobody would have chosen, most often heavily overweight one employer or one sector. No single-account tool sees this, which is why it survives so long undetected.

The four that genuinely need a person
| Item | Why software cannot do it |
|---|---|
| Beneficiary designations | They override a will and are commonly out of date; nothing in a portfolio tool prompts a review |
| The household view | Requires seeing accounts, income and obligations that no single platform holds |
| Equity compensation | Vesting, exercise timing and concentration risk interact with tax in ways a model portfolio cannot see |
| Sequencing across tax years | Deciding what to realise this year versus next is judgement about your whole situation, not a calculation |
These are the honest case for paying someone, and they have a shape in common: each requires information that lives outside any single account, or a judgement that depends on your circumstances rather than your holdings. Neither is a limitation that better software fixes, because the constraint is what the tool can see and what it is allowed to decide.
The half you can run this afternoon
Concentration, overlap, total fund cost and cash drag are measurement. So is performance against an index, and so is drift from whatever targets you set. None of it requires professional judgement, and running it first means the paid conversation starts with the interesting questions rather than the arithmetic.
Doing that before a first meeting is covered in analyze your portfolio before you hire an advisor. An assistant connected to your own brokerage account can do the measurement without taking custody, which is how Walnut works, and it does none of the four items above.
What a review will not tell you
Whether your holdings will do well. No part of this list forecasts anything. A review establishes what you own, what it costs, what it risks and how it is arranged, and none of that is a view about future returns. An advisor who converts a review into confident predictions has changed activity without telling you.
Whether you should have bought what you bought. Reviews look forward from where you are. The purchase price of a position matters for tax and for nothing else, and relitigating old decisions is a way of spending a meeting without improving anything.
What the market will do. Worth stating because the request comes up in almost every review and the honest answer is always the same. The allocation question is about how much of an unknowable outcome you want exposure to, which is answerable, rather than about what the outcome will be, which is not.
How to get a review without an ongoing fee
The eight items above describe a piece of work with a beginning and an end, and it is worth noticing that this is not the same shape as an ongoing percentage of your assets. A review is a project; a management fee is a subscription. Many people want the first and buy the second.
Three routes deliver the review on its own. A one-time financial plan for a fixed project fee, after which you implement it yourself. A few hourly sessions with a fee-only planner, which suits people who want the two or three judgement calls rather than the whole document. Or an annual check arranged as a flat retainer, which keeps a relationship without tying the cost to your balance.
Any of them costs a fraction of a percentage-of-assets arrangement over a decade, and all three are covered in the fee-model comparison. The reason to know the eight items first is that it tells you which route you actually need.
The finding that surprises people most
It is rarely the allocation. In review after review the item with the largest consequence is the beneficiary designation, because it overrides a will and because nothing in ordinary life prompts anyone to check it. A retirement account still naming a former spouse does exactly what it says, whatever the will intends.
That is worth sitting with when weighing whether a review is worth paying for. The value is not always better returns or a cleverer allocation. Sometimes it is one form, updated, that no amount of portfolio analysis would ever have surfaced.
FAQ
Will a portfolio review tell me whether my investments will do well?
No, and an advisor who implies otherwise has changed the subject. A review establishes what you own, what it costs, what it risks and how it is arranged across accounts. None of that forecasts returns, and the allocation question is about how much exposure to an unknowable outcome you want rather than what the outcome will be.
Can I get a portfolio review without paying an ongoing fee?
Yes, and it is often the right shape. A review is a project with a beginning and an end, while a percentage of assets is a subscription. A one-time plan for a fixed fee, a few hourly sessions with a fee-only planner, or an annual check on a flat retainer all deliver the work without tying the cost to your balance.
How much does a one-time portfolio review cost?
It varies by planner and by complexity, and the useful point is the shape rather than the number: a project fee or an hourly rate does not scale with what you own, so it stays the same as your balance grows. Over a decade that is a very different total from a percentage arrangement, particularly on a large account.
What does a financial advisor check in a portfolio review?
Allocation against your real horizon, look-through concentration, fund overlap and total cost, asset location across account types, tax lots and wash-sale exposure, cash drag, beneficiary designations, and the household view including a spouse's accounts and any equity compensation. The first six are largely measurable; the last two are the ones that need a person.
Which parts of a portfolio review can I do myself?
Concentration, fund overlap, total fund cost and cash drag are arithmetic, and you can run all four. Allocation, asset location and tax-lot work are partly self-serviceable and partly judgement. Beneficiary designations and the household view genuinely need someone looking across your whole situation.
What do advisors most commonly find?
Three things recur. Concentration nobody chose, usually because several broad funds hold the same large companies. Duplicated funds doing one job for two fees. And out-of-date beneficiary designations, which are not a portfolio issue at all and are frequently the most consequential thing in the review.
What is asset location and why does it matter?
Putting tax-inefficient holdings that generate income in a sheltered account, and tax-efficient ones in the taxable account. It requires holding both types and a view of your tax picture. The gain is recurring and completely invisible if nobody looks across your accounts, which is why it is a clear place professional advice pays.
Why do beneficiary designations matter so much?
Because they override a will. The person named on a retirement account inherits it regardless of what any other document says, and designations are routinely years out of date after a marriage, divorce or death. Nothing about holding a portfolio prompts you to check, which is exactly why a review catches it.
Can software do a portfolio review?
It can do the measurable half well: concentration, overlap, cost, drift, cash drag, and performance against an index. It cannot do beneficiary designations, the household view, equity compensation, or sequencing decisions across tax years, because those need information no portfolio tool holds and judgement no tool applies.
How often should a portfolio be reviewed?
Annually is the common answer for the measurable items, and the more useful trigger is events rather than dates: a job change, a marriage, a house, an inheritance, or vesting equity. Those change the answer far more than twelve months passing does.
What should I bring to a portfolio review?
A list of every account with its type and holdings, recent statements, anything with a beneficiary designation attached, and details of any equity compensation. If a spouse has accounts, bring those too, because the household view is where the findings that matter usually turn up.
