Portfolio risk monitor

See the risks hidden inside your portfolio

Most portfolio trackers show what you own. Guardfolio shows the risk you actually have.

Guardfolio monitors ETF overlap, stock and sector concentration, allocation drift, and portfolio changes across all your investment accounts, then alerts you the moment a risk crosses your limits.

A portfolio risk monitor watches the exposures that build quietly between logins: duplicate holdings, single-stock concentration, sector crowding, and allocation drift across every account you own.

Positioning

What you own vs. the risk you actually have

A tracker answers "what is my portfolio worth?" A risk monitor answers "where am I exposed, and is it getting worse?" Guardfolio reads your holdings across every account and surfaces the exposures that hide between them.

One risk view across every connected account: health score, concentration, ETF overlap, sector exposure, and drift.
Monitored risks

The risks hidden inside your portfolio

Each risk below has its own free tool. A risk monitor connects them: Guardfolio tracks all of them together and alerts you when one crosses your limit.

Hidden ETF overlap → Two funds can hold the same stocks. See your true duplicate exposure. Stock concentration → When one position quietly grows into an outsized share of your portfolio. Concentration calculator → Measure how much of your portfolio sits in your top holdings. Allocation drift → How market moves push your allocation away from your target. Correlation risk → Holdings that look diversified but move together in a downturn. Volatility and drawdown → How much your portfolio swings, and its deepest decline.
Metrics

Alerts

What an alert actually looks like

You set the limits. Guardfolio watches every account and sends one clear alert by email or Telegram the moment a limit is crossed, not on every price move.

01

Set your limits

For example: no single stock above 10%, no sector above 30%, a drift band of 5% from target.

02

We analyze each sync

Holdings and prices are checked after portfolio data updates across your connected accounts.

03

A limit is crossed

A position grows, a sector crowds, or your allocation drifts past your band.

04

You get one clear alert

Email or Telegram, with what changed and which limit it crossed, so you can decide what to do.

Example Guardfolio risk alert showing a concentration limit crossed across connected accounts
Alerts fire on the threshold breaches you choose, not on routine market noise.
Aggregation

Connect every account for a true risk picture

Risk hides between accounts. A stock you hold directly in one brokerage can also sit inside an ETF in your IRA. Guardfolio rolls every account into one exposure view, so concentration and overlap are measured against your whole portfolio.

Guardfolio connects to 30+ brokers and exchanges through established aggregators (Plaid and SnapTrade), including Schwab, Fidelity, Vanguard, Robinhood, E*TRADE, TD Ameritrade, and Interactive Brokers. Retirement accounts (401(k), IRA, Roth IRA, SEP IRA, and many employer plans) are supported, and you can add any account manually. Guardian Pro currently monitors stocks, ETFs, and mutual funds; cryptocurrency monitoring is available on Guardian Elite. See supported connections →

Methodology and data

How the numbers are calculated

Every score and alert is built from your actual holdings and published fund data, with the formulas documented so you can check them.

Risk signal What it measures Data source Freshness
ETF overlap Shared underlying holdings across your funds Published fund holdings As fund holdings are refreshed
Concentration Weight of your largest positions, with look-through into ETFs Your connected holdings As holdings and prices change
Sector exposure GICS sector weights across the whole portfolio Holdings and sector classification As prices move
Allocation drift Current weights vs. your target bands Your targets and live holdings As prices move
Volatility and drawdown Annualized variability and peak-to-trough decline Price history Daily

The exact formulas behind each score are documented in our metrics methodology and alert methodology. Guardfolio provides analysis and monitoring for educational purposes, not personalized investment advice.

Portfolio drift in action: How it happens silently

Markets shift your allocation every day. Without monitoring, you won't know until you're dangerously off-target.

Workflow

Your monitoring routine in four steps

Effective monitoring connects returns to risk context: benchmark fit, drift, concentration, and overlap in one place. Full checklist →

1

Aggregate every account

Most investors hold positions across 2–4 accounts. Connect them to a unified tracker so your risk picture reflects total exposure.

2

Set your risk thresholds

Decide what "out of bounds" means for you. Some investors choose to review when a single position passes 10%, a sector passes 30%, or allocation drifts more than 5% from target. You set the limits.

3

Turn on automated alerts

Manual monitoring fails because it depends on memory. Guardfolio sends email and Telegram alerts the moment drift, concentration, or volatility changes materially.

4

Review only when triggered

Good monitoring does not mean checking daily. Trust your system to flag problems and intervene only when a threshold is breached. For most passive investors, that means acting 3–5 times per year.

Frequently Asked Questions

What is a portfolio risk monitor?

A portfolio risk monitor is a tool that repeatedly checks your investments for risk, not just value. It tracks exposures like ETF overlap, single-stock and sector concentration, allocation drift, volatility, and drawdown across all your accounts, and alerts you when one crosses a limit you set.

How is a risk monitor different from a portfolio tracker?

A tracker shows what you own and how it is performing. A risk monitor goes further: it looks through your funds to find duplicate and concentrated exposure, watches how your allocation drifts as markets move, and tells you when something needs attention. Most trackers show what you own; Guardfolio shows the risk you actually have.

What risks does Guardfolio monitor?

Guardfolio monitors eight risk signals: a portfolio health score, allocation drift, single-position concentration, sector weights, ETF overlap, volatility, maximum drawdown, and correlation between holdings. Each one also has its own free tool you can use before connecting an account.

Can it find hidden ETF overlap and stock concentration?

Yes. Many investors hold the same companies several times without realizing it, because two funds can share large positions, or a stock sits inside an ETF you also own directly. Guardfolio looks through your funds to the underlying holdings, so concentration and overlap are measured against your whole portfolio. Start with the free ETF overlap checker.

How do risk alerts work?

You set the limits that matter to you, for example a maximum weight for any single stock or sector, or how far your allocation can drift from target. Guardfolio evaluates the latest synchronized portfolio data and sends one alert by email or Telegram when a limit is crossed, rather than notifying you on routine price moves.

Which brokerages and account types are supported?

Guardfolio connects to 30+ brokers and exchanges through Plaid and SnapTrade, including Schwab, Fidelity, Vanguard, Robinhood, E*TRADE, TD Ameritrade, and Interactive Brokers. Retirement accounts such as 401(k), IRA, Roth IRA, and SEP IRA are supported, and you can also add any account manually. Guardian Pro currently monitors stocks, ETFs, and mutual funds; cryptocurrency monitoring is available on Guardian Elite.

Is it safe to connect my accounts?

Connections are read-only and run through established aggregators (Plaid and SnapTrade) with bank-level encryption, so Guardfolio never sees or stores your broker password. Guardfolio is not a broker: it cannot place trades or move money, and you can disconnect any account at any time.

Does Guardfolio give investment advice?

No. Guardfolio provides analysis and monitoring for educational purposes and is not an investment adviser. It helps you see and track risk in your portfolio so you can make your own decisions or discuss them with a professional.
