Free Portfolio Analyzer - Full Portfolio Report
Enter your holdings (stocks and ETFs) and this free portfolio analyzer runs a full checkup on one page: an overall diversification score, portfolio risk analysis, asset allocation and sector exposure, Fama-French factor exposure, and the correlation and overlap between your holdings. Free, no sign-up, and no account linking.
Enter your real portfolio - individual stocks, ETFs, and funds all work. Weights are normalized automatically. Nothing is stored; the portfolio lives only in your URL.
Asset allocation
Asset types
Sector exposure of the equity sleeve (60% of the portfolio)
The other 40% (bonds, gold, etc.) has no sector. Stocks use curated sector labels; funds are decomposed by returns-based style analysis (the sector mix they behave like).
Factor exposure (Fama-French + momentum, 180 months)
Read: defensive (beta < 0.85), large-cap tilt. Factors explain 82% of monthly variance (R²); annualized alpha 2.93% (statistically significant). Loadings with |t| ≥ 2 are reliable; smaller ones are noise.
Correlation between holdings (how much they overlap)
Improve the weak spots: find genuinely uncorrelated additions with the diversification finder, check if the mix survives retirement spending in the withdrawal simulator, or optimize the weights on the efficient frontier. Method details in the methodology.
Portfolio analysis questions, answered
What does the diversification score measure?
The 0-100 score averages four equally weighted components: holdings balance (effective number of holdings after weighting), average pairwise correlation between your holdings, how evenly your money spreads across asset classes, and the diversification ratio (how much portfolio volatility is below the weighted average of your holdings' volatilities). Each component is shown with its own number, so you can see exactly what to improve.
How is sector exposure calculated without fund holdings data?
Individual stocks use a curated sector label (the 11 GICS sectors), cross-checked against sector-ETF correlations. Funds and ETFs are decomposed with returns-based style analysis: a constrained regression of the fund's monthly returns onto the 11 SPDR sector ETFs, which estimates the sector mix the fund behaves like. It is an inference from returns, not a holdings report - close for index funds, rougher for concentrated active funds.
What is factor exposure?
Factor exposure measures how much of your portfolio's return is explained by the classic Fama-French drivers: overall market beta, size (small vs large companies), value vs growth, and momentum. We regress your portfolio's monthly excess returns on Ken French's factor data. A market beta near 1 means fully equity-like risk; a positive size or value loading means a small-cap or value tilt; R-squared says how much of your month-to-month movement the factors explain.
What is a good diversification score?
80+ (grade A) means risk is genuinely spread: many effective holdings, low cross-correlation, several asset classes, and measurable volatility cancellation. 60-79 is typical for stock-heavy portfolios with one diversifier. Below 45 usually means concentrated bets or highly correlated holdings - the diversification finder can suggest what would actually help. A high score is not a return forecast; it measures risk structure only.
Is this portfolio analyzer really free?
Yes - every tool on this site is free with no account: the report, backtesting over a century of data, efficient frontier, Monte Carlo, retirement withdrawal simulation, and correlations. Fee-based sites paywalled most serious analysis; this project exists to keep it open.
What is portfolio analysis?
Portfolio analysis means evaluating your investments as a whole rather than one at a time: what you actually own (allocation), how risky the combination is (volatility, drawdown, Sharpe ratio), what drives its returns (factor exposure), and whether the pieces genuinely diversify each other (correlation). This page runs all of those checks on your real holdings in one pass.
What is portfolio diversification and why does it matter?
Diversification means holding assets that do not all move together, so no single bet can sink the portfolio. It matters because it is the closest thing investing has to a free lunch: combining imperfectly correlated assets can keep expected returns similar while measurably lowering volatility and drawdowns. The diversification score above quantifies how much of that benefit your portfolio actually captures.
How does diversification lower portfolio risk?
When two holdings are imperfectly correlated, their swings partially cancel: one zigs while the other zags, so the combined portfolio moves less than the average of its parts. The report's diversification ratio measures this directly - a ratio of 1.4 means your holdings' weighted average volatility is 40% higher than the portfolio's actual volatility. Low correlation, not the number of tickers, is what does the work.
Is this a free alternative to Morningstar Portfolio X-Ray?
Yes. Like Portfolio X-Ray, this report shows your combined asset allocation, sector exposure, and stock/fund overlap - but it is free with no subscription. And unlike Empower (Personal Capital), there is no account linking: you type in tickers and weights, and nothing is stored. It adds factor exposure and a diversification score that X-Ray never had.
