Stock market heatmap

Sector breakdown
Only assets with a dated, verified change are shown. Equal-area tiles give every asset the same size; BIST data is delayed at least 15 minutes.
No asset has a verified change right now. The map appears here once data has loaded.
Colours show the verified change for the selected period. Cap and volume sizing need verified data for the whole sample. Select a tile to open the asset page.
How to read the heatmap
The heatmap groups the assets in your chosen market by sector and shows each one as a tile coloured by its latest price change. At a glance you can see in which sectors gains prevail and in which losses do.
Tile size
In the equal-area view all tiles are the same size, and each asset takes up the same space on the map. Sizing by market value or trading volume can be used only when that data can be verified for the selected assets. In that case large companies take up more room and shape the overall picture of their sector more strongly.
Colours
Shades of green show gains and shades of red show losses; the deeper the colour, the larger the change. Grey means no change. The colour thresholds are written in the map’s legend and each tile also shows its percentage change, so anyone who finds the colours hard to tell apart can read the value from the figure on the tile.
Which change is shown?
For shares, the change is the difference between the latest session and the previous close; for crypto, it is the movement over the past twenty-four hours. The map uses only observations with a known source and time, and leaves out assets whose change cannot be verified. The source and observation time are written on the source line of each asset’s own page.
Using the map with other pages
You can turn a sector that catches your eye into a detailed list by filtering it in the stock screener. Because colours on a closed exchange reflect the previous session, it is worth checking the session times on the trading hours page.
