Free Portfolio Analyzer
Enter what you hold and see it measured against the S&P 500 over the same days: total return with dividends reinvested, how far it fell at its worst, how the holdings move together, and what your funds hold underneath. Compare up to five portfolios side by side. No signup.
Against the market
What the analyzer measures
Most portfolio tools stop at a return figure. A return on its own cannot tell you whether you were paid for the risk you took, and it hides the two years you spent underwater getting there. Four readings run on every comparison.
Performance against the market
Total return, what the money would be worth now, the deepest fall from peak to trough, the worst single month, and annualized volatility. Each sits beside the same figure for SPY over the identical days, because a 12% year means one thing when the market returned 6% and another when it returned 20%. Returns reinvest every dividend at its ex-date close, so income-heavy holdings are counted in full rather than shown as flat price charts.
What your funds hold underneath
A portfolio of six ETFs is not six bets. Each fund is opened up to its constituents and the weights are added across everything you hold, so a position in a total-market fund, a growth fund, and a technology fund resolves into the handful of companies all three lean on. This is where concentration that looks like diversification shows up.
How the holdings move together
Correlation between every pair you hold, over the window on screen. Holdings that rise and fall in step do not spread risk however different their names are, and pairs that drift apart are doing the work you thought you were paying for.
What past falls did to it
The analyzer finds stretches in market history that resemble the present and replays your holdings through them, so you can see the shape of a drawdown rather than read a single number for it. Each match can be inspected, and any that looks unlike your situation can be dropped from the projection.
How to compare two portfolios
- Type a ticker into the first card. Stocks, ETFs, and funds all work, and pasting a list from a broker statement fills the card in one go.
- Set the weights. Each holding is a percentage and the card adds up to 100. Whatever you are sitting on in cash goes in the cash row, where it drags on the return the way real cash does.
- Press Compare another portfolio and build the second one. To test a single swap, paste the same list and edit the one line.
- Pick how far back to measure, from year-to-date out to 2000, and optionally name a sum of money and the day it went in.
Nothing is saved and nothing is asked for. The comparison lives in the address bar, so the link is the whole thing and sending it to someone shows them exactly what you are looking at.
Questions people ask
Is the portfolio analyzer free?
Yes. No account, no card, and no cap on how many comparisons you run.
Do I enter dollars or percentages?
Percentages. Adding a holding splits the card evenly, and dragging one weight moves the others to compensate. Cash is its own row and only takes what you give it. For dollar figures, set an amount under “Putting in” and the page reports what the portfolio would have been worth.
What does it compare my portfolio against?
SPY, the S&P 500 ETF, measured over exactly the same days as your holdings.
Are dividends included in the returns?
Yes. Every distribution is reinvested at its ex-date close, the convention funds follow when reporting their own performance.
How far back can it measure?
To January 2000, or as far back as the youngest holding goes. Where a holding is younger than the window you asked for, the page says so rather than quietly measuring a shorter stretch.
Can it see what my ETFs hold?
Yes. It looks through every fund to its constituents and adds up your real exposure across the whole portfolio.
What is max drawdown?
The deepest fall from a peak to the trough that followed, before a new peak was made. It answers a different question than total return: not what you would have made, but the worst stretch you would have had to sit through to make it.
What does weighing for least volatility do?
It searches for the weights that would have produced the least volatility, the smallest drawdown, or the best risk-adjusted return over the window on screen. Those weights are fitted to what already happened, so read them as a description of the past rather than a forecast.
How many portfolios can I compare at once?
Up to five, each measured over the same days against the same benchmark, so the columns line up.
