Stock Map: Every US Stock by Sector, Industry and Size
About 4,663 US-listed stocks and ADRs on one grid: rows by sector and industry, columns by market-cap bucket, every tile coloured by its return over the horizon you pick. Industry and sector headers carry the median return and the count, so the map answers which groups moved and how broadly, before you read a single ticker.

The map — one day

Tiles are sorted by market cap within each cell; industries show their 16 largest names per column until expanded. Hover or tap a tile for the name, size, price and every horizon. Names without an SEC industry code sit under Other.
How Stock Map Works
- 1Start from the whole universeEvery symbol in our price universe with a common-stock or ADR share type is a candidate; funds, preferreds, warrants and units are left out. A name also needs a close within the last five sessions and at least a month of history.
- 2Classify by SEC industry codeEach company carries a Standard Industrial Classification code in its SEC filings. Our data provider supplies it for most names and the SEC filing index fills the rest. An editorial table maps the 444 codes to 11 sectors and about 80 industries a trader would recognise, and a short list of symbol overrides fixes the cases where the filing code misleads, such as the payment networks filing as business services.
- 3Size by current share countMarket cap is the provider's current share-class share count multiplied by our latest committed close. Mega is $200 billion and up, Large $10 billion, Mid $2 billion, Small $300 million, Micro below that. A share count that is refreshed monthly cannot be caught on the wrong side of a split.
- 4Colour by returnPick a horizon: one day, one week, one month, three months, year to date or one year. Each tile takes one of seven colours on a fixed scale for that horizon, so a shade means the same thing every day. Industry and sector headers show the median return and the count.
Who Uses Stock Map
Day Traders
A one-glance answer to which industries moved today and whether the move was broad inside them or carried by one name.
Swing Traders
Switch to the one-month or three-month horizon to see rotation: the industries turning green before their sector does.
Sector Analysts
The industry rows are the cross-section: median, count and every constituent by size, without a screener.
Small-Cap Traders
The Mid and Small columns put the names the index-weighted maps hide on equal footing, with Micro one toggle away.
Pro Tips
01
Read the medians before the tiles
The industry median is the honest read of the group; the tiles show dispersion around it. A green median with red tiles is an industry carried by its largest names.
02
Compare columns, not only rows
When the Large column is green and the Small column is red in the same industry, size is the story rather than the industry.
03
Use the search for context
Type a ticker and the map scrolls to it and highlights it inside its industry, so you see the neighbours a chart never shows.
04
Longer horizons for regime, shorter for news
The year-to-date view shows leadership; the one-day view shows what the tape rewarded today. They rarely agree, and the gap is the information.
Common Issues & Solutions
Why is a company in an odd industry?▾
It is classified by the SEC industry code on its filings, which is coarser than the commercial taxonomies. Alphabet files as prepackaged software, for instance. A short override list moves the best-known cases where the code misleads; everything else follows the code, and the mapping table is published so the choice is visible.
How is market cap computed?▾
The provider's current share-class share count times our latest close. The count is refreshed at least monthly, so a split cannot pair a new price with an old count. For multi-class issuers the map sizes the listed share class only.
Why no logos?▾
A ticker and a number are what the map needs to answer its question, and text tiles render 4,700 names in one page without a single image request. Logos may come later as a toggle.
Why are some stocks under Other?▾
A few dozen names have no SEC industry code from either source, usually recent listings or foreign issuers with a different filing form. They sit in an Unclassified row at the bottom rather than being dropped.
Why does a return show as blank?▾
The horizon starts before the stock's history does. A blank is never a zero.
Frequently Asked Questions
What is the Stock Map?▾
A grid of every US-listed common stock and ADR in our universe, about 4,700 names, with rows by sector and industry and columns by market-cap bucket. Each tile is coloured by the stock's return over the horizon you choose, from one day to one year, and every industry and sector header carries the median return and the count.
How many stocks went up today?▾
As of the September 10, 2026 close, 1,511 of 4,663 stocks on the map closed higher, 32%. The strongest industry by median was Broadcasting at +1.6% across 22 names, and the weakest was Metals & Mining at -4.2% across 84.
Which industries are leading this year?▾
Year to date as of September 10, 2026, the strongest industry by median return is Semiconductor Equipment at +63.5% (10 names) and the weakest is Auto Manufacturers at -24.5% (24 names). Across all 4,559 stocks, 54% are up on the year.
How are stocks assigned to sectors and industries?▾
From the Standard Industrial Classification code on each company's SEC filings, mapped by an editorial table to 11 sectors and 79 industries, with a short list of symbol overrides where the filing code misleads. The mapping and the overrides are published files, so every placement can be checked.
What do the size buckets mean?▾
Market cap is the current share count times the latest close. Today the map holds 74 mega caps ($200 billion and up), 824 large ($10 billion to $200 billion), 1,113 mid ($2 billion to $10 billion), 1,294 small ($300 million to $2 billion) and 1,358 micro caps.
What horizons can I view?▾
Six: one day, one week, one month, three months, year to date, one year. Each has its own fixed colour scale so a shade means the same thing on every visit.
How often is it updated?▾
Daily after the US close. Returns come from the day's committed prices; the classification and share counts refresh at least monthly and within a day for new listings.
