A portfolio audit is a structured, written review of what you own, what it costs, how it has performed and whether it still fits your goals. Run it once a year and after major life changes. Work through the ten checks below in order, record a yes or no for each, and act only on the items that fail. The point is a decision you can defend, not a reaction to this week's headlines.
TL;DR
- Audit yearly, and again after a job change, marriage, inheritance, retirement or any shift in your goals or risk tolerance.
- Check ten things: goals, allocation, concentration, overlap, fees, taxes, income, benchmark performance, rules and records.
- Compare performance with a benchmark that matches what you hold, over several years rather than one quarter.
- Fix the biggest mismatch first, and check wash sale and tax consequences before you sell anything at a loss.
- Write your rules down so the next audit tests the plan, not your mood.

What a portfolio audit is, and what it is not
People use "audit" loosely. Here it means a review of your own investment accounts, the kind a careful investor does at a kitchen table. It is not a tax audit, a patent audit or a compliance audit of a fund manager. Those are different jobs with different checklists.
A good personal audit is also not a hunt for new stock ideas. It asks whether the portfolio you have is the portfolio you meant to build. That separation matters. AAII's guidance on monitoring describes an annual higher-level review of allocation, goal progress and life stage, kept apart from the rules you use to select individual securities. Reviewing the plan and picking securities are two jobs, and mixing them is how investors end up reacting to market noise.
Before you start, gather:
- The latest statement from every account: taxable brokerage, IRA, 401(k), HSA if you invest it.
- Your cost basis and purchase dates for taxable holdings.
- Your written goals, or a note on what you would write if you had to.
- Last year's tax return, so you know your bracket and any carried-over losses.
The 10-point portfolio audit checklist
1. Do your goals and time horizon still hold?
Start with the person, not the portfolio. Investor.gov explains that the right asset mix is personal and depends on your time horizon and your ability to tolerate risk. Allocation may need adjusting as you approach a goal, or if your circumstances, risk tolerance or goal change.
Write one line for each goal: what it is, when you need the money and roughly how much. "Retire in 11 years, need $4,000 a month from the portfolio" is useful. "Grow wealth" is not.
Pass: each goal has a date, an amount and a rough share of the portfolio assigned to it.
2. Is your asset allocation where you intended?
Add up every account and calculate your split between stocks, bonds, cash equivalents and anything else. Investor.gov describes asset allocation as dividing investments among those categories. Compare the result to your target. If you never set a target, that is your first finding.
Look at all accounts together. A 401(k) heavy in stock funds plus a brokerage account of growth stocks may leave you far more aggressive than either statement suggests.
Pass: your actual stock, bond and cash percentages are within a range you chose in advance. A band of five percentage points either way is a common starting point, and our guide to the 5/25 rule for rebalancing shows how to set one without overtrading.
3. Are you concentrated in one stock, sector or theme?
Diversification works in two layers. Investor.gov says to spread investments between asset categories and within each category, across companies and industry sectors. It also notes that narrowly focused funds may require several funds to be well diversified, and that diversification may limit losses but does not eliminate risk.
Run these quick tests:
- What is your largest single position as a percentage of the whole portfolio?
- What share sits in your largest sector?
- How much of your wealth depends on your employer, through salary, stock options and company shares combined?
There is no official ceiling that fits everyone. Pick your own limit, write it down and see whether you are inside it. Winners that drifted upward are the usual culprit.
Pass: no single holding or sector exceeds the limit you set.
4. Do your funds overlap?
Three funds with three different names can hold the same top ten stocks. Open each fund's holdings page and look at the largest positions. If you own an S&P 500 index fund, a large-cap growth fund and a handful of mega-cap stocks, you probably own the same companies several times over.
Pass: you can name what each holding does that the others do not.
5. What are you paying in fees?
Fees are the one return component you control. The SEC's investor bulletin on fees and expenses explains that fund operating costs are deducted from fund assets, which lowers your returns, and that advisory fees can also have a big effect over time.
List each cost:
- Expense ratio of every fund and ETF.
- Advisory or management fees, if anyone manages money for you.
- Trading commissions or transaction fees.
- Subscription costs for research, signals or software.
Total them in dollars per year, not just percentages. Seeing a four-figure annual number focuses the mind.
Pass: you can justify each cost by what it delivers.
6. Are taxes and asset location in order?
Three questions here. Which holdings sit in taxable accounts, and which in tax-advantaged ones? Do you have unrealized losses you could harvest? Are you about to trigger a gain you could time better?
Be careful with losses. IRS courseware states that a wash sale occurs when you sell securities at a loss and acquire the same or substantially identical securities within 30 days before or after the sale. The loss is then not currently deductible and is added to the basis of the replacement shares. That is a window of 61 days in total, and it applies across your accounts, so check dividend reinvestment settings too. Our walkthrough of tax-loss harvesting rules covers the mechanics.
Tax rules are specific to your situation. Before a large sale or a harvesting plan, talk to a CPA or enrolled agent.
Pass: you know the tax effect of any trade before you place it.
7. Does your income match what you need?
If you rely on the portfolio for cash flow, list the dividends and interest it produced over the past twelve months and compare that to your spending needs. Then ask where the yield comes from. A very high yield on one holding can signal risk, not generosity.
Retirees should also check how many months of spending sit in cash or short-term holdings, so a downturn does not force sales at bad prices. Our 19-position model portfolio for retirees shows one way to bucket that.
Pass: income covers the planned need, or you know exactly which holdings you would sell to cover the gap.
8. Is performance measured against the right benchmark?
This is where many audits go wrong. FINRA's guide to benchmarks cites the S&P 500 for large-cap U.S. stocks and the Russell 2000 for U.S. small-cap funds. Check what assets your chosen benchmark tracks, and compare over several years rather than a single quarter or year.
Match the benchmark to the holding. A bond fund measured against the S&P 500 will look terrible and prove nothing. For a whole portfolio of stocks and bonds, blend two benchmarks in your actual proportions.
Be skeptical of any performance figure, including your own memory of it. The SEC's Investor Bulletin on performance claims urges comparison against an appropriate, comparable benchmark. It tells investors to separate actual past performance from guarantees, projections and back-tested results, and to watch for cherry-picked periods that leave out down markets. Past results can inform a review, but they cannot predict what comes next.
When you calculate your own return, include dividends, fees and the effect of deposits and withdrawals. Our guide to portfolio analytics metrics explains which measures reveal whether results came from skill or from simply taking more risk.
Pass: you know your net-of-fee return for at least three years against a benchmark that fits.
9. Do you have written rules, and did you follow them?
An audit without rules is just opinion. Write down when you buy, when you sell, how large a position can be, and what makes you rebalance. Then check your trades from the past year against them. Every trade you cannot explain by a rule is a finding.
If you want a ready template, our investment rules checklist has ten yes/no checks you can adapt.
Pass: at least 90 percent of last year's trades match a written rule. The threshold is yours to set, but pick it before you count.
10. Are your records and beneficiaries current?
Confirm that beneficiary designations match your wishes, that account ownership is correct, and that you can find cost basis for every taxable lot. Keep a one-page summary of every account and login location for a spouse or executor. It is dull work and the one item nobody regrets.
Pass: someone you trust could find and understand your accounts in an afternoon.
Scoring your audit
Count the passes. There is no magic grade, but a rough read helps:
| Passes | What it suggests | Next step |
|---|---|---|
| 9 to 10 | Plan and portfolio are aligned | Note the date and repeat next year |
| 6 to 8 | A few gaps | Fix the highest-impact one first, usually allocation or concentration |
| 5 or fewer | The portfolio drifted or never had a plan | Rebuild the target allocation before trading |
How often to audit, and what triggers an early review
A full audit once a year is a sound default. AAII's monitoring article describes the annual review and also treats significant life changes as triggers to revisit goals and target weights. Practical triggers include:
- Marriage, divorce, a new child or a death in the family.
- A job loss, a big raise, or a business sale.
- An inheritance or other windfall.
- Retirement, or a retirement date moving closer than five years.
- A change in your tolerance for losses, which is often revealed during a steep market drop.
A falling market alone is not a trigger. Investor.gov notes that many professionals suggest rebalancing regularly, typically every six to 12 months, as its rebalancing guidance puts it. Checking daily tends to produce trades, not improvements.
What to do when the audit finds a problem
A failed check is information, not an emergency. Handle problems in this order.
- Rank by impact. A 40 percent stock-heavy mismatch with your risk tolerance matters more than a fund with a slightly high expense ratio.
- Look at tax cost. In taxable accounts, check the gain or loss and holding period before selling. Redirect new contributions and dividends to underweight areas first, which often fixes drift without a sale.
- Fix in tax-advantaged accounts first. Selling inside an IRA or 401(k) usually creates no current tax bill, though you should confirm your plan's rules.
- Check wash sale exposure on any loss sale, including purchases in a spouse's or retirement account.
- Change one thing at a time and log why. Next year you will want to know what you changed and what happened.
- Phase large moves. If a correction is big, splitting it over several weeks reduces the regret of bad timing. Our portfolio drift control guide covers how to keep allocation on target afterward.
If the portfolio's main problem is that you do not have time, discipline or confidence to run these steps, that is a legitimate finding too. Options range from a fee-only adviser to a rules-based system. Our comparison of AI and advisor options gives six checks for choosing between them.
Our perspective: audit the process, not just the holdings
We built StockPilot around a simple observation: most self-directed investors do not fail because they pick one bad stock. They fail because they have no fixed rules for sizing, replacing and reducing positions, so each decision is made under pressure.
That is why we publish a transparent 19-position model portfolio, six income-producing positions and 13 AI-selected growth positions, and issue after-hours alerts only when predefined investment and risk criteria call for a change. In unfavorable markets the system can reduce growth exposure and move capital toward Treasury ETFs. Subscribers mirror the trades in their own brokerage accounts. We never take custody, and every trade stays the investor's decision.
Every check in this article is easier when the rules exist before the audit. Allocation, concentration and position size become questions with answers. We would rather you leave with a documented process, whether it is ours or your own, than with another list of stock tips. Read our view on auditability in AI portfolios if you want to see how we think about proof.

If you would rather not run the audit alone
StockPilot Premium costs $147 per month. It gives you the 19-position model portfolio, buy and sell alerts after market hours, position sizing guidance, automated risk management during downturns and performance analytics. You mirror the portfolio in your own brokerage account, so the audit above stays yours to run, with a ready-made rules framework to test against.
See how it works on the StockPilot Premium page, and read the risk disclosure first. Investing involves risk, including the loss of principal, and no system guarantees outperformance. Before subscribing, you can also check how portfolio mirroring works and which registrations to verify.
FAQ
How often should I audit my investment portfolio?
Once a year is a reasonable default for most investors, as AAII's monitoring guidance describes. Add an unscheduled review after a significant life change such as retirement, an inheritance or a new job. Market swings alone are not a reason to audit.
What should I look at first in a portfolio audit?
Start with your goals and time horizon, then your actual asset allocation across all accounts. Everything else, including fees and individual holdings, is judged against those two. If you have no written target allocation, set one before you trade.
Which benchmark should I compare my portfolio to?
Choose one that tracks a comparable market segment. FINRA cites the S&P 500 for large-cap U.S. stocks and the Russell 2000 for U.S. small-cap funds. For a mixed portfolio, blend benchmarks in the proportions you actually hold, and compare over several years.
Can I sell losers during an audit to cut my taxes?
Sometimes, but watch the wash sale rule. If you buy the same or a substantially identical security within 30 days before or after a loss sale, the loss is not currently deductible. Talk to a CPA or enrolled agent before a large harvesting plan.
Is a portfolio audit the same as rebalancing?
No. An audit reviews goals, risk, costs, taxes and performance. Rebalancing is one possible action that comes out of it, when your allocation has drifted from target.
