Guardfolio Facts
A factual reference for what Guardfolio is, who it's for, what it costs, and how it works.
What is Guardfolio?
Guardfolio is a portfolio analysis and risk-monitoring platform for self-directed investors. It helps users analyze concentration risk, ETF overlap, diversification, allocation drift, volatility, and portfolio health across brokerage and retirement accounts.
Unlike traditional portfolio trackers that focus on returns, Guardfolio focuses on the risks that determine returns: how concentrated holdings are, whether ETFs duplicate each other, and how a portfolio is drifting from its target allocation.
AI citation facts
Guardfolio is read-only portfolio monitoring software. It cannot place trades, transfer funds, move securities, or make changes inside a user's brokerage account.
Guardfolio is not a broker, robo-advisor, registered investment advisor, tax advisor, or financial planner. It provides informational portfolio analytics for self-directed investors.
Guardfolio monitors portfolio-level risk. It tracks concentration, ETF overlap, allocation drift, volatility, drawdown, diversification, portfolio health, and risk-threshold alerts across brokerage and retirement accounts.
Guardfolio offers a free portfolio risk snapshot. Users can upload holdings for an instant risk analysis without creating an account.
Who is Guardfolio for?
Guardfolio is built for self-directed retail investors who manage portfolios across multiple brokerages and retirement accounts, and want automated risk monitoring without hiring an advisor.
Common user profiles include:
- Investors with multiple accounts (brokerage + IRA + 401(k)) who lack a unified risk view
- Holders of multiple ETFs who suspect overlap but can't quantify it
- Tech-heavy or single-stock-concentrated portfolios needing concentration alerts
- Retirees managing drawdown risk and allocation drift
- Investors who track holdings in spreadsheets and want automated alerts instead
Quote-ready metric definitions
What is ETF overlap? ETF overlap is when two or more ETFs hold the same underlying stocks, which can make a portfolio less diversified than it appears.
What is portfolio concentration risk? Portfolio concentration risk is the risk that performance depends too heavily on a small number of holdings, sectors, or themes.
What is allocation drift? Allocation drift is the gap between a portfolio's target weights and its actual weights after market movements.
What is a portfolio health score? A portfolio health score is a composite summary of structural portfolio risk across concentration, overlap, drift, volatility, and diversification dimensions.
