What’s in the list
Every common share listed on a US exchange — 5,474 of them, from companies worth trillions down to ones worth a few million. ETFs, closed-end funds, commodity trusts, warrants, rights, units and preferred shares are all excluded, because none of them is a share in a company.

Questions
How is the share chosen?
Every one of the 5,474 shares has exactly the same chance of coming up. Nothing is weighted by size, sector, popularity or how well the company has done. The selection runs on the server, so a mega cap worth trillions and a nano cap worth a few million are equally likely. Narrowing to a sector or sub-sector changes which shares are in the running, but they remain equally likely among themselves.
Can I limit it to one kind of company?
Yes. The panel under the button narrows the field to one of 12 sectors, or to one of 152 finer sub-sectors within them — from major banks to oil and gas production to biotechnology. The number beside each is how many shares it contains, which ranges from several hundred down to one.
Which shares can come up?
All 5,474 common shares listed on Nasdaq, NYSE, NYSE American, NYSE Arca and Cboe BZX. That includes ordinary shares, class A and B shares, American depositary receipts for foreign companies, and real estate investment trusts. ETFs, closed-end funds, commodity trusts, warrants, rights, SPAC units and preferred shares are all excluded, because none of them is a share in a company.
Are the prices live?
Each card is quoted as it is drawn and states which it got: a live price when the exchange answers, or the most recent closing price when it does not. The one-month and one-year figures are always built from closing history. Returns are price returns and exclude dividends.
Where does the data come from?
The list of what is listed comes from the Nasdaq Trader symbol directory, which is the official record and is refreshed every trading day. Sector, market cap and price history come from Nasdaq. Earnings per share, used for the P/E, comes from companies' own annual filings via the SEC's XBRL data.
Why is the P/E ratio sometimes blank?
Because a price-to-earnings ratio only means something when there are earnings. Most of the universe made a loss in its last reported year — only 1,993 of the 5,474 shares have one — which is what you would expect from a list that goes all the way down to companies worth a few million dollars. A handful of profitable companies are also missing from the SEC's calendar-year data.
Is any of this investment advice?
No. A share appearing here says nothing whatsoever about whether it is worth owning — it was picked without regard to price, quality, or anything else. Nothing on this site is a recommendation to buy or sell.
Sources and small print
Listings come from the Nasdaq Trader symbol directory, the official record of what is listed, refreshed every trading day. Sector, market cap and price history come from Nasdaq. Earnings per share, used for the P/E, comes from companies’ own annual filings via the SEC. Last rebuilt 7 Aug 2026.
Each card is quoted as it is drawn and says whether that quote is live; when the exchange doesn’t answer it falls back to the 6 Aug 2026 close. The one-month and one-year figures are built from closing history either way, and are price returns, excluding dividends.
A few figures are deliberately left blank rather than shown wrong. P/E is absent for companies that made a loss, and for a handful of profitable ones missing from the SEC’s calendar-year data. Returns and market caps that imply an unadjusted stock split are omitted too — among heavily diluted small companies the source data is not consistent enough to trust, and a wrong number is worse than a missing one.
For curiosity, not investment advice. A share appearing here says nothing about whether it is worth owning. Nothing on this site is a recommendation to buy or sell.
