Nasdaq 100 Heatmap
The Nasdaq 100 is where Big Tech lives — the 100 largest non-financial companies on the Nasdaq, dominated by names like Apple, Microsoft, Nvidia, Amazon, Meta and Alphabet. This live heatmap paints them all in one view: green for gainers, red for losers, sized by market cap, so you can read tech’s mood — and what is moving QQQ — in seconds.
Free, real-time and color-coded — no sign-up, no paywall.
How to read a heatmap
A heatmap turns an entire market into a single, color-coded picture so you can see what is moving at a glance — no scrolling through hundreds of tickers.
- Color = performance. Green tiles are up on the day and red tiles are down. The deeper the shade, the bigger the move — a sea of green means a broad rally, a wall of red means a sell-off.
- Tile size = weight. Bigger tiles are bigger companies by market capitalization (or heavier index weight). Mega-caps dominate the map, while smaller names sit in the corners.
- Grouped by sector. Tiles are clustered into sectors — technology, financials, energy and so on — so you can instantly tell whether a move is broad-based or driven by one corner of the market.
- Tap any tile to drill in and switch the time frame from today's move to weekly, monthly or year-to-date performance.
Prices update as the market moves and the colors shift with them. Data may be delayed depending on the exchange.
What is the Nasdaq 100 heatmap?
The Nasdaq 100 heatmap is a single-screen map of the index’s 100 constituents. Each company is a rectangle: its color shows the day’s performance and its size shows market capitalization. Because the index leans heavily toward technology and growth, the map is usually ruled by a handful of enormous tech tiles.
That concentration is exactly why the heatmap is so useful here — one glance tells you whether the mega-caps are carrying the market higher or dragging it down.
How the Nasdaq 100 heatmap tracks QQQ
QQQ is the popular ETF that tracks the Nasdaq 100, holding the same companies in the same market-cap weights. So this heatmap is effectively a live picture of QQQ: when the giant tech tiles glow green, QQQ tends to rise; when they turn red, it falls — often regardless of what the smaller tiles are doing.

Frequently asked questions
What is a Nasdaq 100 heatmap?
It is a visual map of the Nasdaq 100 index where each of the 100 companies is a colored tile. Green means the stock is up, red means down, and tile size reflects market capitalization. It is a fast way to read what tech and growth stocks are doing.
Does the Nasdaq heatmap track QQQ?
Effectively, yes. QQQ holds the Nasdaq 100 in the same market-cap weights, so the heatmap mirrors QQQ. When the largest tech tiles are green, QQQ tends to rise; when they are red, it tends to fall.
Why is the Nasdaq heatmap so tech-heavy?
The Nasdaq 100 is dominated by large technology and growth companies, and it is market-cap weighted, so those mega-caps take up the biggest tiles. A few names like Apple, Microsoft and Nvidia can drive the whole index.
Is the Nasdaq 100 heatmap free and live?
Yes. It is free with no sign-up and updates in real time as the market trades, though data may be delayed depending on the exchange.
