Where do the prices come from?

From you. Download daily closing prices from your broker, your data provider or a spreadsheet and drop the CSV on the page. The page does not fetch quotes from any website. The two built-in samples are simulated prices for fictional companies, so you can see every chart before loading your own file.

What CSV layouts work?

Three: a long table with date, symbol and close columns; a wide table with a date column and one column per symbol; or one file per symbol with the usual Date, Open, High, Low, Close, Adj Close, Volume columns (the file name becomes the symbol). Adjusted close is preferred when present. Several files can be added at once.

What does the peer average mean?

For each name, the peer average is the equal-weight average of the other selected names, each rebased to 100 on the first day of the window. It is what an equal split across the peers on day one would be worth since. The gap between the two lines is shown in index points.

No. The file is read and analysed inside your browser tab and is never sent anywhere. There is no sign-in.

Compare stocks against their peers

Every price rebased to 100, each name against the average of the others, drawdowns from the high and how closely they move together. Load closing prices from a CSV, or open a simulated sample. Runs in this tab; nothing is uploaded.

Pick Chips & cloud to see every chart with simulated data, or drop a CSV of daily closes. Download prices from your broker or data service: most offer a CSV of price history. A file per symbol works; so does one table with a column per symbol.

How it works

Where do the prices come from?: From you. Export daily closes from your broker, your data provider or a spreadsheet. This page never fetches quotes from a website. The two samples are simulated prices for fictional companies.
Which CSV layouts work?: A long table (date,symbol,close), a wide table (date,AAA,BBB,...) or one file per symbol with Date, Open, High, Low, Close, Adj Close, Volume; the file name becomes the symbol and adjusted close is used when present. Dates like 2026-10-30, 10/30/2026, 30.10.2026, Oct 30, 2026 and Unix timestamps are read; prices like $1,234.50 and 1.234,50 too.
What do the numbers mean?: Return: change from the first to the last close in the window. vs peers: the name's rebased value minus its peer average, in points. Ann. return: compound yearly rate, shown for windows of a year or more. Ann. vol: standard deviation of daily returns, scaled to a year. Max drawdown: the deepest fall from a running high. Beta: how much the name moved per 1% move in its peer average.
Different start dates or holidays?: The comparison starts when every selected name has a price and stops at the earliest last date, and the page says which name set the limit. A date one market was closed carries that name's previous close forward.
