Portfolio analysis
Analyze a stock portfolio properly: how the money is allocated, where the risk concentrates, how it has performed against a benchmark, and what the companies you own actually reported to the SEC. Paste a list of tickers and get the first pass in a few seconds, with no account.
No account, no brokerage connection, no payment details.
What portfolio analysis answers
A balance tells you the total. These are the questions it does not answer.
Allocation
What you actually own, by weight rather than by position count. Two holdings can look equal in a list and be 40% and 4% of your money.
Concentration
Where the risk is stacked. Five technology names are one bet, not five, and they tend to fall on the same days.
Sector and region mix
How the portfolio splits across sectors, industries and countries, so you can see the exposure you took on by accident rather than on purpose.
Performance
Time-weighted return, so deposits and withdrawals do not read as performance, plus price return and dividend-inclusive total return side by side.
Drawdown and volatility
The worst peak-to-trough fall the portfolio has actually taken, its volatility, Sharpe and Sortino ratios, beta and value at risk.
Benchmark comparison
The portfolio against a benchmark on the same basis, measured over the same window. Comparing a price return to a total return quietly flatters one side.
Dividend income
Projected annual income, portfolio yield, yield on cost and income received by quarter, counted at the shares held on each ex-date.
What each holding reported
The filed financials behind every position: revenue, margins, how each figure ranks against its industry peers, and what the company most recently filed with the SEC.
A worked example
This is a real run over six well-known companies, produced by the same engine the free health check uses. The holdings are an example set, not a recommendation, and no share counts are involved: every figure below is read from the companies’ own filings and current market data.
Spread across 4 sectors
No single sector dominates by count. (Position sizes could still concentrate it.)
Every covered holding is profitable
All holdings with reported figures had positive net income in their last fiscal year.

Financial statements come from SEC EDGAR and are as reported, which means they may be unaudited or later restated. Valuation figures such as P/E and market cap are derived from recent market prices. Informational only. Not investment advice.
Where the numbers come from
Financial statements are read from SEC EDGAR, the SEC’s public filing database, and shown as the company reported them. Where a figure is calculated rather than filed, the calculation is shown instead of a filing link, because a citation has to equal the thing it cites.
Prices and valuation figures come from market data providers and refresh live during US market hours. Institutional ownership comes from quarterly Form 13F filings, insider trades from Form 4, and short interest from FINRA, which owns and is the source of that data.
The full method, including what is derived and what the known limitations are, is on the methodology page.
Common questions
- What is portfolio analysis?
- Portfolio analysis is the work of understanding what a set of holdings actually adds up to: how the money is allocated, where the risk concentrates, how it has performed against a benchmark, and what the underlying companies report. It is different from simply tracking a balance, which tells you the total and nothing about how you got it.
- Can I analyze my portfolio for free?
- Yes. The portfolio health check runs on a list of tickers with no account and no payment, and returns sector concentration, valuation spread, profitability and recent SEC filings. A free account adds live tracking with the full analytics.
- How many holdings do I need?
- The health check accepts up to 30 tickers. Analysis of concentration and correlation gets more meaningful above about five holdings, because below that a single company dominates the result.
- Where do the numbers come from?
- Financial statements come from SEC EDGAR, the SEC's public filing database, as the companies reported them. Prices and valuation figures such as P/E and market cap come from market data providers. Nothing here is an analyst estimate.
- Do you need my brokerage login?
- No. There is no brokerage connection and no read access to any account. You enter tickers, or import a CSV your broker exports. The analysis is read-only and holds no custody of anything.
- Is this investment advice?
- No. Everything on this site is information drawn from public filings and market data. It is not a recommendation to buy or sell anything.
