What is a stock heat map?

It is a visual where each company is a rectangle: the size shows its market cap, and the color shows how much its price rose or fell. It lets you read the whole market at a glance.

What do the size and color mean?

Size reflects market capitalization (large companies are bigger on the map). Color reflects price change: green = gain, red = loss, grey = data unavailable.

How often is the data updated?

1–2 times per day. It is not a real-time source — it is meant for a daily overview, not intraday trading.

Can I choose a different index or period?

Yes. Use the buttons at the top to switch between S&P 500, Dow 30 and Nasdaq 100, and between the 1-day, 1-week or 1-month change.

Where does the data come from?

Prices and market caps come from Yahoo Finance, while the company lists and sectors come from the official indices (S&P 500, Dow Jones, Nasdaq-100).

How to read the map

Rectangle size = the company’s market capitalization (its total value). Large companies take up more space.
Color = price change over the selected period: green for a gain, red for a loss, grey for missing data. The more intense the color, the bigger the move (up to ±3%).
Companies are grouped by sector and industry so you can quickly see where the market is moving — for example whether technology is up while energy is down.

About this data

Data comes from Yahoo Finance and updates 1–2 times per day (not real time). Changes are computed from closing prices.

We cover the largest US companies (S&P 500, Dow 30, Nasdaq 100). European and small-cap names are not included yet.
