Market Heatmap
Every stock in the major NSE sector indices, in one picture. Tile size is the money that actually went through it today — not market cap — so the big blocks are where today's volume went. Colour is the day's move.
Loading the market…
Live during market hours from NSE's own sector-index feed, refreshed about every 3 minutes; the last close outside them. A stock appears exactly once — where sector indices overlap, the more specific sector keeps it. Educational only, not investment advice.
Reading the heatmap
Every sector on the exchange, with every stock inside it, sized by the money that actually traded through it today and coloured by the move. Size is the part people skip, and it is the part carrying most of the information.
Size is turnover, not market capitalisation
A large tile means a lot of money changed hands in that name today. That is a different statement from "this is a large company", and the difference is the point of the layout. A mid-cap that has swollen to occupy a visible share of its sector is a stock something is happening in, whatever the colour says.
The pairing to look for is a large tile with a strong colour: a big move on heavy turnover is a move with participation behind it. A strong colour on a small tile is a big move on very little money, which is a thinner and far less reliable signal — and often just a stock with no liquidity being pushed around.
Reading rotation instead of direction
The most useful thing on this page is not whether the market is up. It is which sectors are green and which are red on the same day. Banks up and IT down is money moving between sectors, not into or out of equities — a rotation, and rotations tend to run for weeks rather than days.
A day where everything is the same colour is a market-level move: index flows, a macro number, global cues. A day where the index barely moved but the sectors are sharply split is an active day that the index number is hiding, and it is usually the more informative of the two.
Where it will mislead you
A whole sector glowing green on the strength of one heavyweight is common and looks like breadth. Check whether the colour is spread across the tiles or concentrated in the largest one; the highlights page carries the advance-decline reading that settles it.
And the map has no memory. A stock down 3% today after being up 20% over a month reads as red here, identically to one that has been falling for a month. The colour is a single session, nothing more.
