How to Review an Investment Portfolio You Did Not Build

To review an investment portfolio you did not build, start with control and tax facts, not performance. Identify who owns each account, what type of account it is, how every holding supports your goals, what it costs, and what would happen if you sold it. Only then should you decide what to keep, simplify, or replace.

This order prevents three expensive errors: trading before authority is established, selling before basis is documented, and adopting a late spouse’s strategy as though your income needs and risk capacity were identical.

Freeze unnecessary trading while you map the accounts

Pausing is not the same as ignoring the portfolio. Continue required administration, distributions, and cash management, but avoid discretionary sales until you have a complete inventory.

For every account, record:

• legal owner and current registration;
• account type, such as taxable brokerage, IRA, employer plan, trust, or estate;
• custodian and account number ending;
• beneficiary or transfer-on-death status;
• cash balance and every holding;
• acquisition date and reported cost basis, when available;
• restrictions, surrender charges, or transfer limits; and
• adviser and fee arrangement.

Do not combine an inherited IRA, an estate account, a trust account, and your personal brokerage account on a single tax assumption. Each has different control and distribution rules. Resolve spousal inherited-retirement choices before moving retirement assets.

Give every holding a job

The SEC explains that asset allocation should reflect the goal, time horizon, and risk an investor can tolerate. Your first question is therefore not “Has this fund performed well?” but “What household purpose is this money meant to serve?”

Assign each pool to a purpose:

• near-term spending and known obligations;
• a multi-year stability reserve;
• long-term income and growth;
• a future home, care, family, or charitable goal; or
• an asset held for a legal, tax, or estate reason.

Money needed soon should not depend on selling volatile assets at a favorable time. Long-term money may need enough growth exposure to address inflation and longevity. The allocation must fit your plan, not a generic age formula.

If a holding has no identifiable job, flag it for review. Do not sell it solely because it is unfamiliar.

Measure concentration and diversification

Calculate each holding as a percentage of the whole investable portfolio, including accounts at different firms. A collection of several funds is not necessarily diversified if the funds own many of the same companies or track the same market segment.

Look for:

• one company representing an outsized share;
• heavy exposure to a former employer;
• several funds with overlapping holdings;
• one industry or country dominating risk;
• large bond exposure with similar maturity or credit risk; and
• cash scattered across accounts without a defined purpose.

The SEC notes that diversification operates both between asset categories and within them. It can reduce concentration risk, but it cannot prevent loss. Handle a large single-stock position with a specific concentrated-holding review, including its basis and tax consequences.

Document tax facts before a sale

Cost basis affects the gain or loss reported when taxable property is sold. IRS Publication 551 says inherited property’s basis is generally tied to fair market value at death, subject to important exceptions and estate-tax consistency rules. Jointly owned property, retirement accounts, trusts, gifts made shortly before death, and assets with missing records require careful review.

For each taxable lot, preserve:

• the custodian’s basis record;
• date-of-death values and estate appraisals;
• any Schedule A from Form 8971;
• confirmation of which portion was inherited;
• reinvested distributions and prior adjustments; and
• the specific shares proposed for sale.

“Stepped-up basis” is not a sufficient instruction. Ask the tax professional to confirm the actual basis and holding period for the specific asset before execution. A sale can also create capital gains, losses, or taxable fund distributions.

Calculate the full cost in dollars

Investment cost can exist at several layers: advisory fee, fund expense ratio, sales load, account fee, trading cost, annuity charge, and tax cost. Ask for an annual dollar estimate using your current balance.

The SEC says mutual-fund and ETF costs appear in a standardized prospectus fee table and that even small fee differences can materially affect returns over time. Compare the correct share class and include adviser compensation separately.

Build a one-page fee table:

Cost layer	Annual percentage	Estimated dollars	Where verified
Advice or management			Agreement/Form ADV
Fund expenses			Prospectus
Account and transaction fees			Custodian schedule
Product-specific charges			Contract

Use the deeper investment-cost audit when the structure is complicated.

Review the adviser as well as the portfolio

An adviser who worked with your spouse does not automatically become your adviser. Ask the person to explain the portfolio without jargon, disclose how the firm and individual are paid, identify conflicts, and provide the governing documents.

Verify registration and disciplinary history through Investor.gov, which routes searches to IAPD or FINRA BrokerCheck. Registration is not an endorsement, but an inability or reluctance to provide a verifiable record is a reason to stop.

Ask for two written recommendations: the proposed change and the reasonable alternative of doing nothing for now. Each should show expected fees, tax effects, risks, liquidity, and exit terms. Review any proposal using Reading a Recommendation Before You Sign It.

Turn the review into an action sequence

Use four labels:

1. Protect now: fraud controls, required distributions, expiring deadlines, or uninsured cash.
2. Research: unclear ownership, missing basis, complex products, or restrictions.
3. Decide: allocation, diversification, fees, and simplification after facts are complete.
4. Monitor: acceptable holdings that need no immediate change.

For every trade, record the reason, account, tax review, fee, and effect on the target allocation. Review the whole plan after major changes and at a regular interval; do not let daily market movement set the agenda.

A good portfolio review produces understanding before activity. The measure of success is not how many holdings were replaced. It is whether every asset now has a documented owner, purpose, risk, cost, tax treatment, and decision.
